Hey guy's! Darrin, quite simply, prepare, as in grind clean, V out about least half the thickness you're welding to both pieces and leave a little gap for penetration, High amps on your welder, set gas to 18-20. Solid wire welding with mig is already low hydrogen. If you're going to war then preheat if you're not "don't bother" inert mig gas prevents hydrogen from affecting your welds. watch your welding while you're doing it, you can see if it's flowing or sitting on top. if it's not a flowing a flatish weld then you need more heat or you're dragging instead of pushing. If you welder is on high amps it will put plenty of heat into the material anyway. Don't try and weld an oxy cut that still has slagg on it as it won't work.
