I've been browsing around trying to gather as much info as possible regarding welders and their capabilities lately. It seems most people for home garage or small shop use just have some of the smaller stick or mig machines. From what I gather with the Bobcat and Trailblazer type units, they seem to have the capability of doing all types of welding instead of just 1 type.. Plus they are also generators, plasma cutters and who knows what else. They are pretty pricey machines, I've seen them running between $2000-$4500 for some used to brand new units. If price really wasnt an issue, would you run one of these big units, or is there a reason you wouldn't want to? There are tons of variants of these with different options, gas, LP, diesel engines, etc... Anyone have feedback? I plan on doing lots of fab work, bumpers and stuff eventually. My thoughts so far are that an engine ran welder wouldn't require me to deal with the 110/220 specific outlets, and if the machine could handle plasma cutting too and be a generator and whatever else, thats less equipment to buy seperately. On an awesome note, today I was running to Lowes and Home Depot with my girlfriend for some unrelated stuff, and when we passed the very limited welding stuff aisle, she says: "Why are you even looking here, you know they only have the small stuff. Why don't you just get one of the big heavy duty machines? I mean, if you have to spend just a few grand more to get something good, just do that." I almost proposed right then and there! Ok, so back to my topic. Tell me why I should or shouldn't look into these Bobcat and Trailblazer engine driven welders. Discuss.
