I have an arc welder. I suck at it. I'm afrade if I start to weld to the frame I'll blow holes in it. So I've posted up on pirate. THey tell me I need a big monster 240 volt. But as I look at my stuff and what I really want to do, it seems I'll never weld anything thicker than 1/4 but mostly will weld 1/8 or thinner. Frame is fairly thin. I want to get good enough to tack together a cage and take it and have it welded by a pro. DOM tubing is not thick. Same with some tube fenders, etc. Fairly thin stuff. When I need to weld a front bumper I have the arc welder to fall back on. SO do I really need a 220 volt welder?
