Who makes airco welders?

Airco welders were manufactured by the Airco company, which was known for producing welding equipment and industrial machinery. Founded in the early 20th century, Airco became a significant player in the welding industry until it was acquired by the Illinois Tool Works (ITW) in the late 1980s. Today, Airco equipment may still be found in various applications, though it is less common due to the brand's integration into ITW's broader portfolio.
