Kenneth from Pennsylvania asks Joe:
Do you have Weldcraft TIG Torch parts to fit a Miller DB20 water cooled TIG torch? Specifically a gas lens, collet and nozzle for .040? through .125″ diameter tungsten electrodes?
This question brings up a couple of points. First off, did you know that Miller and Weldcraft are related? Both are owned by the Illinois Tool Works (ITW). Currently all Miller TIG torches are sold as Weldcraft, taking advantage of the brand recognition of Weldcraft, a leader in the industry. Some earlier Miller torches were made by another company, but to quality standards.
Which leads me to point number two.
Most TIG torches parts are interchangeable. There are some exceptions, and certainly with some of the cheaper non-name brands you’ll find that the materials are not as good and the tolerances are, well, not tolerable…. But with quality brand names like CK, Diamondback, Lincoln, etc the parts should interchange.
