This would be a different question if he already didn't own one of the best welding migs ever made.
I oiled the fan and did replace the V switch but,,,,, the thing has 1000's of hours on it, ran way past its rated cycle and was way too small when I bought it. I should have bought another full size the same day. For the hobby gang its great, its one of the cheapest with the only draw back of not hooking up with a spool gun.
There is a lot of focus on the new multi process, they have their place and tig gets a lot of attn. but really ranks up there with things most people don't need.
This is different than want, like the fuggin holes in the table. A spool gun is really the *** saver and most of the fabrication in a common life support/small biz is steel. I havnt torch welded since mig.
The 200 isn't huge but it can do the work. Its slow but the world is a lighter place than it was. A home place has so much sheet, equipment like mower decks and tractors, the 200 gives enough punch to do limited trailer and bumper work.
I remember pricing welders 25 yrs ago, some of these are nearly the same in todays dollars. I bought an spt and it was 650 from a dealer in 92, not much over 700 today and some of that is very recent.
I bought a 255 in 94 maybe and it was 300 more than a Hobart 230 is today which is a better welding machine.
