HOW DOES AC WELDING DIFFER FROM DC WELDING

You'll notice how much quieter welding is with the DC machine over the AC machine.

If I recall correctly, 7018 used to only be available for use on DC but now they have 7018 that will burn pretty well on either. DC will allow you to use quit a few other rods that won't run AC such as stainless and aluminum.

You will also notice less "buckshot" splatter and smoother welds with DC

You will notice that the arc is easier to strike and maintain. I also felt like I had more control of the arc. That it seemed to produce smoother welds.

You can also weld thinner metal.
