Hi, I am in the market for a new MIG welder. I have a decent little 90amp flux core welder. Good enough for around the farm but I want something better with out all the splatter and mess. Looking for a gas compatible MIG. My question is do I really need 240v? I mainly just do sheet metal and maybe some small brackets and stuff. I am not building a chassis or frames and will probably never weld anything thicker than 3/16". I want to get a decent MIG, but also don't want to have to wire another 240v circuit in my garage since I am about capacity for the electric in there now. So, do I really need 240v, or will a 120v with gas probably be much better than the flux core that I am using now? Thanks!!!
