I'm aware of the limitations of a 110v welder. I have a friend who is a 'semi pro' welder. Welding isn't his day job, but he does a lot of side work doing offroad frames, roll cages, custom Al fuel cells, etc. He suggested
years ago that I upgrade.
When I built my shop, I brought in 220v just to run a bigger welder.
I'll probably keep the smaller welder because it's very handy for 98% of the stuff I do, and if I need to, I can throw it into the back of the bus and work somewhere else. The Millermatic... not so much.
I
really like the spool gun setup on the 210 and 251, paticularly since I have the Lincoln Al setup for my 110v welder. I
can weld aluminum with it, but I have to be desperate. The 251 is about $600 more; I could get the spool gun for that
