...and a lot has changed! All i used on the job was an acetylene torch for cutting and a lincoln arc welder.

I would like to get back into it to shore up my skillz.

I was at harbor freight and they had an arc welder for 79 bucks about the size of a lunchbox! to me thats like going to 1955 and showing someone a cell phone.

where would you start if youre essentially a beginner again?

i'll probably be willing to spend the extra money to avoid cheap chinese crap so i guess lincoln or miller would be the way to go....but what kind? the multiprocess models like the multimatic look attractive so I could practice with each type.

Im not really sure about what fields of use MIG and TIG are best suited for....and why stick/mig/tig for whatever application. (assuming mild steel)
