I've got my HF TIG welder setup and running, but after doing a number of test welds to get back in the swing of welding and laying down a nice bead, I'm running into problems.
First off, all is hooked up correctly and I've reviewed the TIG 101 info on pirate's web site (very helpful!).
The problem is I'm getting a lot of air bubbles, voids, whatever you want to call them in my welds. I've welded before, mostly gas and arc, so I'm not a total newbie, but it's been a while. The metal surfaces were blasted and cleaned very well beforehand. No slag! I've talked to one of the welders where I work and his guess is that I may have a bad tank of Argon (impurities).
Anyone else note this problem using one of these HF welders? I want to check around first before going through the likely hassle of getting my Argon supplier to give me a different tank of gas.
