The Tweco story began way back in the late 1930s, 1936 in particular, when Ray Townsend had the bold and hitherto unheard of idea of improving contemporary welding quality by improving ground connections. Shortly thereafter, Townsend started marketing his novel “redhead” ground clamp to wide acclaim. A year later, the name of the brand he founded, Townsend Welding Equipment Company was abbreviated to Tweco. Townsend then began selling his innovative products nationally. 

Over the course of the consequent decades, Tweco persisted in the expansions of its product lines. This move enabled it to diversify its welding accessories offerings to include metal arc holders along with quick-connect cable connectors. In the long run, Tweco went on to unveil a new MIG welding gun, which immediately proved to be a gamechanger that revolutionized the entire industry. The company went through a series of acquisitions, first by Pacific Lumber Company in 1981 and then by Thermadyne 6 years later. Throughout this period of time, Tweco remained at the forefront of innovation in the sector and retained its hard-won reputation for churning out high-quality products. This continues to be the brand’s never-changing focus, which still continues to this present age. 

Tweco was very recently acquired by Victor/ESAB, and still pushes its drive to be a market leader in the welding supplies industry. At the same time, its new owner has started consolidating its various brands including Thermal Arc Machines, going through a facelift and christened with a brand new name. As for Tweco, it has solidified its credibility and is now a household name, continuing a long tradition of strong welding equipment sales nationwide and even globally. Let us now review two of the most outstanding products from this one of a kind brand.
