It's important to note that the majority of TIG torches can fit onto just about any welder, with the right connection. However, you always need to confirm that the TIG torch you're considering is compatible with your welder and if DINSE cable connections or adaptors are needed. For the most part, TIG welding is used for welding thin materials and will rarely need to operate on more than 150Amps. This means your TIG torch can be used on just about any size welder.
