Not sure where to put this but since most people do their own welding here in this forum I thought it would be best suited here. Ok, I need some more info. I have a Hobart 140 welder, it is the 110v version that can be used with flux or gas. I will need to weld my suspension with it and some bumper parts. Most stuff is between 3/16 and 1/4" thick. Question is can I do it with the flux core only or do I need to change up and use Co2? I really don't want to buy a bottle and have it filled eventhough I do plan on getting one later for a refill set up. What is the consensus here??? All you pro welders please chime in and don't tell me I should have bought a 220v I had no $$$ then.
