I've got a little hobart like that in the shop and use it out on the road from time to time. I've run 6,7, 8?? 10lb spools through it and no telling how much gas, replaced the lead and gun once(had something fall on the gun...destroyed) bare wire, 4/40 with 75/25 and 30 wire works awesome. I've run aluminum through it too to do some minor fence/gate repairs. Little argon, aluminum wire and some preheat on the piece I'm welding and works great, no spool gun required. Gotta say it has sure made it's money back, excellent little machine for the price.
