Have you ever used the Gianttech combo units? I have one that I use as a plasma cutter but it also has a TIG torch. Different technology than what I am used to. There is no tungsten tip sticking out. Have you had any experience with these?

I have not. but if there is no tungsten sticking out, you are looking at the plasma torch.
it uses a separate torch for plasma cutting and for tig welding.
