Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation As used in this report, the term “Company,” except as otherwise indicated by the context, means Lincoln Electric Holdings, Inc. and its wholly-owned and majority-owned subsidiaries for which it has a controlling interest. The consolidated financial statements include the accounts of all legal entities in which the Company holds a controlling interest. The Company is also considered to have a controlling interest in a variable interest entity (“VIE”) if the Company determines it is the primary beneficiary of the VIE. Investments in legal entities in which the Company does not own a majority interest but has the ability to exercise significant influence over operating and financial policies are accounted for using the equity method. The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these unaudited consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. However, in the opinion of management, these unaudited consolidated financial statements contain all the adjustments (consisting of normal recurring accruals) considered necessary to present fairly the financial position, results of operations and cash flows for the interim periods. Operating results for the six months ended June 30, 2020 are not necessarily indicative of the results to be expected for the year ending December 31, 2020 . The accompanying Consolidated Balance Sheet at December 31, 2019 has been derived from the audited financial statements at that date, but does not include all of the information and notes required by GAAP for complete financial statements. For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 . COVID-19 Assessment In March 2020, the World Health Organization categorized the current coronavirus disease (“COVID-19”) as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. COVID-19 continues to spread throughout the United States and other countries across the world, and the ultimate duration and severity on the Company's business remains unknown. New and changing government actions to address the COVID-19 pandemic continue to occur on a regular basis. As a result, the countries in which the Company’s products are manufactured and distributed are in varying stages of restrictions. Certain jurisdictions have had to re-establish restrictions due to a resurgence in COVID-19 cases. Additionally, although many of the Company’s customers have begun to re-open or increase operating levels, such customers may be forced to close or limit operations as any new COVID-19 outbreaks occur. Even as government restrictions are lifted and economies gradually reopen, the shape of the economic recovery is uncertain and may continue to negatively impact the Company's results of operations, cash flows and financial position in subsequent quarters. Given this current level of economic and operational uncertainty over the impacts of COVID-19, the ultimate financial impact cannot be reasonably estimated at this time. The Company’s consolidated financial statements presented herein reflect estimates and assumptions made by management that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting periods presented. Such estimates and assumptions affect, among other things, the Company’s goodwill, long-lived asset and indefinite-lived intangible asset valuation; inventory valuation; assessment of the annual effective tax rate; valuation of deferred income taxes and income tax contingencies; the allowance for doubtful accounts; measurement of compensation cost for certain share-based awards and cash bonus plans; and pension plan assumptions. Events and changes in circumstances arising after June 30, 2020, including those resulting from the continued impacts of COVID-19, will be reflected in management’s estimates for future periods. New Accounting Pronouncements: This section provides a description of new accounting pronouncements ("Accounting Standard Update" or "ASU") issued by the Financial Accounting Standards Board ("FASB") that are applicable to the Company. The following ASUs were adopted as of January 1, 2020 , unless otherwise noted below: Standard Description ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20), issued August 2018. ASU 2018-14 modifies disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The ASU also requires an entity to disclose the weighted-average interest crediting rates for cash balance plans and to explain the reasons for significant gains and losses related to changes in the benefit obligation. These disclosure requirements will be reflected in the Notes to the consolidated financial statements in the Company's year ended December 31, 2020 Form 10-K. ASU No. 2018-13, Fair Value Measurement (Topic 944) , issued August 2018. ASU 2018-13 eliminates, amends and adds disclosure requirements related to fair value measurements. The ASU removes disclosure requirements pertaining to the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements. Refer to Note 17 to the consolidated financial statements for further details. ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), issued June 2016. ASU 2016-13 modifies disclosure and measurement requirements related to credit losses. Topic 326 requires that an entity estimate impairment of trade receivables based on expected losses rather than incurred losses. The adoption did not have a material impact on the Company's consolidated financial statements. ASU No. 2020-04, Reference Rate Reform (Topic 848) , issued March 2020. ASU 2020-04 provides temporary optional guidance to ease the financial reporting burden associated with the expected market transition from the London Inter-Bank Offer Rate ("LIBOR") to alternative reference rates. The Company adopted the ASU on March 12, 2020 and it is effective through December 31, 2022.

Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of the Company’s operating leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on information available at commencement date to present value the lease payments. The Company has operating leases for sales offices, manufacturing facilities, warehouses and distribution centers, transportation equipment, office equipment and information technology equipment. Some of these leases are noncancelable. Variable or short-term lease costs contained within the Company’s operating leases are not material. Most leases include one or more options to renew, which can extend the lease term from 1 year to 11 years or more. The exercise of lease renewal options is at the Company's sole discretion. Certain leases also include options to purchase the leased property. Leases with an initial term of 12 months or less are not recorded on the Company's Condensed Consolidated Balance sheets. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants. Total lease expense, which is included in Cost of goods sold and Selling, general and administrative expenses in the Company's Consolidated Statements of Income, was $5,990 and $11,209 in the three and six months ended June 30, 2020 and $6,546 and $12,435 in the three and six months ended June 30, 2019 , respectively.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company recognized $27,037 of tax expense on pretax income of $109,605 , resulting in an effective income tax rate of 24.7% for the six months ended June 30, 2020 . The effective income tax rate was 20.1% for the six months ended June 30, 2019 . The increase in the effective tax rate for the six months ended June 30, 2020 , as compared with the same period in 2019, was primarily due to recording the tax expense associated with a valuation allowance in 2020, smaller tax benefits related to the vesting of stock based compensation in 2020 and income tax benefits for the settlement of tax items recorded in 2019. As of June 30, 2020 , the Company had $20,235 of unrecognized tax benefits. If recognized, approximately $17,259 would be reflected as a component of income tax expense. The Company files income tax returns in the U.S. and various state, local and foreign jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state and local or non-U.S. income tax examinations by tax authorities for years before 2015. The Company is currently subject to U.S., various state and non-U.S. income tax audits. Unrecognized tax benefits are reviewed on an ongoing basis and are adjusted for changing facts and circumstances, including progress of tax audits and closing of statutes of limitations. Based on information currently available, management believes that additional audit activity could be completed and/or statutes of limitations may close relating to existing unrecognized tax benefits. It is reasonably possible there could be a reduction of $2,165 in previously unrecognized tax benefits by the end of the second quarter 2021 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES The Company uses derivative instruments to manage exposures to currency exchange rates, interest rates and commodity prices arising in the normal course of business. Both at inception and on an ongoing basis, the derivative instruments that qualify for hedge accounting are assessed as to their effectiveness, when applicable. Hedge ineffectiveness was immaterial in the six months ended June 30, 2020 and 2019. The Company is subject to the credit risk of the counterparties to derivative instruments. Counterparties include a number of major banks and financial institutions. None of the concentrations of risk with any individual counterparty was considered significant at June 30, 2020 . The Company does not expect any counterparties to fail to meet their obligations. Cash Flow Hedges Certain foreign currency forward contracts were qualified and designated as cash flow hedges. The dollar equivalent gross notional amount of these short-term contracts was $66,201 at June 30, 2020 and $59,982 at December 31, 2019 . During March and April 2020, in anticipation of future debt issuance associated with the Notes, referenced in Note 12, the Company entered into interest rate forward starting swap agreements to hedge the variability of future changes in interest rates. The forward starting swap agreements were qualified and designated as a cash flow hedge. The changes in fair value are recorded as part of AOCI, and upon completion of debt issuance and termination of the swaps, are amortized to interest expense over the life of the underlying debt. The dollar equivalent gross notional amount of the long-term contracts was $100,000 at June 30, 2020 and have a termination date of August 2025. Fair Value Hedges From time to time the company will enter into certain interest rate swap agreements that are qualified and designated as fair value hedges. At June 30, 2020 , the Company had no interest rate swap agreements outstanding. The Company terminated $50,000 of interest rate swaps in the six months ended June 30, 2020 which resulted in a gain of $6,629 that will be amortized to interest expense over the remaining life of the underlying debt. Net Investment Hedges The Company has cross currency swap agreements that are qualified and designated as net investment hedges. The dollar equivalent gross notional amount of these contracts is $50,000 as of June 30, 2020 and December 31, 2019 , respectively. Derivatives Not Designated as Hedging Instruments The Company has certain foreign exchange forward contracts that are not designated as hedges. These derivatives are held as economic hedges of certain balance sheet exposures. The dollar equivalent gross notional amount of these contracts was $375,396 and $363,820 at June 30, 2020 and December 31, 2019 , respectively.

The Company measures the fair value of foreign exchange contracts and swap agreements using Level 2 inputs based on observable spot and forward rates in active markets. The deferred compensation liability is the Company’s obligation under its executive deferred compensation plan. The Company measures the fair value of the liability using the market values of the participants’ underlying investment fund elections. The fair value of Cash and cash equivalents, Accounts receivable, Short-term debt excluding the current portion of long-term debt and Trade accounts payable approximated book value due to the short-term nature of these instruments at both June 30, 2020 and December 31, 2019 . The Company has various financial instruments, including cash and cash equivalents, short and long-term debt and forward contracts. While these financial instruments are subject to concentrations of credit risk, the Company has minimized this risk by entering into arrangements with a number of major banks and financial institutions and investing in several high-quality instruments. The Company does not expect any counterparties to fail to meet their obligations.

ASU 2018-14 modifies disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The ASU also requires an entity to disclose the weighted-average interest crediting rates for cash balance plans and to explain the reasons for significant gains and losses related to changes in the benefit obligation. These disclosure requirements will be reflected in the Notes to the consolidated financial statements in the Company's year ended December 31, 2020 Form 10-K. ASU No. 2018-13, Fair Value Measurement (Topic 944) , issued August 2018. ASU 2018-13 eliminates, amends and adds disclosure requirements related to fair value measurements. The ASU removes disclosure requirements pertaining to the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements. Refer to Note 17 to the consolidated financial statements for further details. ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), issued June 2016. ASU 2016-13 modifies disclosure and measurement requirements related to credit losses.

ASU 2020-04 provides temporary optional guidance to ease the financial reporting burden associated with the expected market transition from the London Inter-Bank Offer Rate ("LIBOR") to alternative reference rates. The Company adopted the ASU on March 12, 2020 and it is effective through December 31, 2022. As of June 30, 2020, the Company has not utilized any of the optional guidance, however, it will continue to assess the potential impact on the Company’s debt contracts and hedging relationships through the effective period. The Company is currently evaluating the impact on its financial statements of the following ASU: Standard Description ASU No. 2019-12, Income Taxes (Topic 740) , issued December 2019. ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740.

The ASU is effective January 1, 2021 and early adoption is permitted.
Segments	The Company's business units are aligned into three operating segments. The operating segments consist of Americas Welding, International Welding and The Harris Products Group. The Americas Welding segment includes welding operations in North and South America. The International Welding segment includes welding operations in Europe, Africa, Asia and Australia. The Harris Products Group includes the Company’s global oxy-fuel cutting, soldering and brazing businesses as well as its retail business in the United States. Segment performance is measured and resources are allocated based on a number of factors, the primary measure being the adjusted earnings before interest and income taxes (“Adjusted EBIT”) profit measure. EBIT is defined as Operating income plus Other income (expense). EBIT is adjusted for special items as determined by management such as the impact of rationalization activities, certain asset impairment charges and gains or losses on disposals of assets.
Lessee, Leases [Policy Text Block]	The Company determines if an agreement is a lease at inception. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of the Company’s operating leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on information available at commencement date to present value the lease payments. The Company has operating leases for sales offices, manufacturing facilities, warehouses and distribution centers, transportation equipment, office equipment and information technology equipment. Some of these leases are noncancelable. Variable or short-term lease costs contained within the Company’s operating leases are not material. Most leases include one or more options to renew, which can extend the lease term from 1 year to 11 years or more. The exercise of lease renewal options is at the Company's sole discretion. Certain leases also include options to purchase the leased property. Leases with an initial term of 12 months or less are not recorded on the Company's Condensed Consolidated Balance sheets. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants.
Financial Instruments	The Company uses derivative instruments to manage exposures to currency exchange rates, interest rates and commodity prices arising in the normal course of business. Both at inception and on an ongoing basis, the derivative instruments that qualify for hedge accounting are assessed as to their effectiveness, when applicable. Hedge ineffectiveness was immaterial in the six months ended June 30, 2020 and 2019. The Company is subject to the credit risk of the counterparties to derivative instruments. Counterparties include a number of major banks and financial institutions. None of the concentrations of risk with any individual counterparty was considered significant at June 30, 2020 . The Company does not expect any counterparties to fail to meet their obligations. Cash Flow Hedges Certain foreign currency forward contracts were qualified and designated as cash flow hedges. The dollar equivalent gross notional amount of these short-term contracts was $66,201 at June 30, 2020 and $59,982 at December 31, 2019 . During March and April 2020, in anticipation of future debt issuance associated with the Notes, referenced in Note 12, the Company entered into interest rate forward starting swap agreements to hedge the variability of future changes in interest rates. The forward starting swap agreements were qualified and designated as a cash flow hedge. The changes in fair value are recorded as part of AOCI, and upon completion of debt issuance and termination of the swaps, are amortized to interest expense over the life of the underlying debt. The dollar equivalent gross notional amount of the long-term contracts was $100,000 at June 30, 2020 and have a termination date of August 2025. Fair Value Hedges From time to time the company will enter into certain interest rate swap agreements that are qualified and designated as fair value hedges. At June 30, 2020 , the Company had no interest rate swap agreements outstanding. The Company terminated $50,000 of interest rate swaps in the six months ended June 30, 2020 which resulted in a gain of $6,629 that will be amortized to interest expense over the remaining life of the underlying debt. Net Investment Hedges The Company has cross currency swap agreements that are qualified and designated as net investment hedges. The dollar equivalent gross notional amount of these contracts is $50,000 as of June 30, 2020 and December 31, 2019 , respectively. Derivatives Not Designated as Hedging Instruments The Company has certain foreign exchange forward contracts that are not designated as hedges. These derivatives are held as economic hedges of certain balance sheet exposures. The dollar equivalent gross notional amount of these contracts was $375,396 and $363,820 at June 30, 2020 and December 31, 2019 , respectively.
