I'm thinking about buying a 230v Miller welder... the new DVIj-2 dual voltage unit. I've done quite a bit of residential wiring but saw a comment recently in another forum that confuses me. The person said that a dryer circuit requires a "hot/hot/neutral" circuit.... but welders need a "hot/hot/ground" circuit. I've never wired anything and omitted the neutral connection... someone please help me here... thanx
