Also when your butting 2 pieces like you have if you grind a chamfer on each edge where you want the welds it will give you a stronger weld as you have larger weld area, it also gives you a flatter weld with hardly any grinding required.
Hey, yes sorry I was referring to my MIG in particular, I'm sure with more current it would work absolutely fine. Ten four on the chamfering, I'll keep that in mind for future.
