THanks for the continued feedback guys. My plan for the class is to go ahead and keep working on the stick. I am looking for a good used stick welder to place at the office for repairing and modifying my canoe trailers. I do not want to have to mess with tanks and stuff here at the shop since space and time is limited. Then after the I complete this class sign back up and just work on mig.
Not trying to tell you what to do or anything, but I thought I'd point out that you can MIG weld without using any shielding gas; you have to use a different type of wire called Flux Core wire, which basically has the shielding gases built into the wire itself. Despite the sometimes negative reputation it has, FC
can produce nice welds, it's just not quite as dummyproof as standard MIG welding. But with enough practice you can get good at it.
But I'd definitely agree with getting good at stick welding if you can, because it's probably the most commonly available type of welder, and it's also one of the most versatile welding processes. Another added benefit is that it's probably one of the most weather-proof, which is important for field repairs, since there's no shielding gas to be blown away by the wind.
One last thing that I thought I'd point out - I'm not sure what brand of welders they're using at your school (Miller, Lincoln, Hobart, etc), but my guess is that it's probably quality welding equipment. When the class is over, you're probably going to want a welder for your garage. I'd recommend not buying a crappy one (i.e. Harbor Freight) just because it's cheap. I've used HF MIG welders and plasma cutters, and after getting used to using high-end equipment, it can be very frustrating using cheap equipment. At the very least, I'd recommend trying a HF product before buying one, as you wouldn't to buy one blind, and get it home only to be disappointed. Again, that's just my opinion, YMMV.
