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...
