I have spent the last 10 or so years screwing around welding. i started off with a crappy 110v stick welder which was a pain but did make metal stick together. then i moved to a crappy 220v chicago electric flux mig welder. That worked decent but i could never get a good looking weld out of it, accompanied by a ton of spatter and the fumes were pretty bad. That little POS burned out in the middle of a home made dune buggy. At this point i had a slight clue what i was doing and lucked out finding a real machine in the form of a Miller 210. Along with this i invested in a tank and set it up to run gas. this was about 6 years ago since then i havent looked back that machine has paid for itself 10 times over building trailers and small repair work, and fixing my busted #$%* and building bikes.
The lincoln 180 is a good little machine long as your mindful of the duty cycle. they will do flux or upgrade to full gas overall a great little machine. although i would reccomend just starting with full gas
