I am using gasless mig welding. My mig is a 220V mig and is rated as being able to weld 1/4" thick metals (I am assuming 1/4" is the thickness of one of the pieces and not the thickness of both pieces combined). My question is can I weld mild steel that is upto 3/8" thick? Also, will tack welding (w/o using beads of welds or intermittent welds) be good and strong enough for mild steel w/o putting welding beads? |
