I'm starting to shop around for a TIG machine and ran across a local ad for a used Lincoln 175 TIG. I've read some comments on this machine in the archives of this group, but I've still got a few questions:1) Lincoln's website doesn't have any info on the 175 TIG. Is it still in production? And if not, does Lincoln have a reputation for supporting out-of-production equipment?
2) The asking price is $750. I haven't had a chance to talk to the seller, so I don't know much about it except that it supposedly has been "used very little". Assuming it's in decent shape and has all the original equipment (regulator, torch, pedal), is this price smoking, typical, or inflated for a used 175?3) Is there anything in particular I should watch out for in a used 175 (common problems, parts that frequently go bad, etc.)?
4) I assume output amps are directly proportional to input amps, so if I crank the dial much above the half-way point I'll risk popping the breaker on my 30-amp 220V dryer circuit. Is this a correct assumption? Would using a water-cooled torch alter the equation at all?5) (For Ernie) I noticed your comment about this machine not being particularly good for stick welding. Could you elaborate?
6) What are the odds of finding a used inverter TIG in the same power range for anywhere near this price?
