Hobart 180
I'm a die hard Miller Guy, as thats what I use at work. That being said, when we where having our welders calibrated, due to ISO requirments, I asked the technician about what he thought about " home owner " types of welders ( smaller than Industrial sized units ). He stated that for the under 200 amp size there about, Hobart was a pretty good unit, anything bigger, Miller. Can't realy say anything about Lincoln, other than I've used them from time to time at work. To me, its kind'a like carb vs FI on a motor, ones a little " crisper " on the response. To me, the Millers are a little " crisper ". For the record, I bought a Hobart Handler 180. Got it from Indiana Oxy for a little over $500, added a tank, and bought a Speed Pro auto darkening helmet ( use the same helmet at work, with the fresh air feature ), so inner/outter lenses are a non issue. If you can swing it, try for a 220v unit, instead of a 110v, and practice your welding on some projects ( welding cart? , work/welding table? ). Welding is cool, good luck. Al
