Welding Connector Manufacturers
In the initial hour of research, information on the product range related to welding connectors, available model numbers, link to the product catalog/webpage, industry standards followed, available certifications, and intermateability of the connector components were provided for Lenco Welding Accessories Ltd. For the full research, similar information has been provided in the attached spreadsheet for the following ten (10) North American welding connector manufacturers: Tweco, Praxair, Miller Electric Manufacturing Co., Lincoln Electric Holdings, Jackson Safety, DINSE, W.W. Grainger, Hobart Welding Products, Illinois Tool Works, and US Forge. Also, snapshots of these products (wherever available) have been pasted in the spreadsheet.

For the list of 10 additional companies (other than Lenco) manufacturing welding connectors in North America, we concentrated mainly on the US and Canada. Since Mexico and the countries to the south of Mexico (like Guatemala, Honduras, and others) are often classified under Latin America, we did not consider these countries. An extensive search yielded the names of these reputed manufacturers.
For the range of products under welding connectors manufactured by the above companies, we scanned the product offering webpages of these companies and listed all items under welding connectors in the attached spreadsheet. Barring two items (both of Lincoln Electric Holdings) for which the pictures were not available on the website, we have pasted the snapshots of all the other items in the spreadsheet. The information related to the intermateability of the connectors were available in the product catalogs and product webpages (except for the products of Miller Electric and Grainger). A quick read of these product catalogs and webpages will reveal the intermateability.
For the certifications received by the companies, we searched on the company websites and also conducted external searches. Other than Grainger, we could find all the certifications received by these companies. However, the search for the industry standard based on which the welding connectors are manufactured by the above companies was not so straightforward. Barring DINSE that explicitly mentions that all welding connectors are manufactured as per IEC 60974-12, the other companies do not mention the manufacturing standard of the connectors. Hence, we had to search the product catalogs of other related equipment manufactured by these companies, like arc welding power sources, arc welding torches, and welding helmets to find the corresponding standard. A great source of information was this page from NEMA that lists all the arc welding standards. Some companies have mentioned that all their products are manufactured as per some particular standards. We found such information and completed the attached spreadsheet.
