I'm a welding novice. I've been using my Lincoln 135 Plus for a number of automotive projects at home, but have wanted a TIG welder. I did some TIG welding a number of years ago and liked the precision and appearance of TIG in comparison to MIG.
Anyhow, I've been offered on very extended loan (meaning I can have it for free) an old PowCon 300ST that I've been told works. I have dinky shop and the small size of the PowCon makes it very attractive. I've searched the archives and come up with some info but am interested in a couple of things. I'm hoping that the folks on this NG can help a bit.1) The unit does not come with a foot controller and I'd like one. I would prefer not to spend $280 for a pedal (one of the archived posters said that's what's wanted for a new one) and if I can score a relative cheapy on the used market, I'd be happier. Do I need to buy one specifically for the PowCon or are these "universal"? If they're not universal but not specific to the PowCon, what do I need to look for?
2) Someone in one of the posts I perused commented that inverter machines are not good for welding aluminum. True? False? Limitations?3) The posts I've read seem to indicate that these are good machines, but expensive to repair. Any other comments?
4) I know that there are 300SS, 400SS, 300SM, 400SM, and 300ST available. Anyone know how the machines differ?5) Any recommended TIG reference books? And yes, I am going to take a welding class or three...
