Can anyone explain the difference between AC and DC welding? I understand that AC gives a plasma arc and DC gives a good clean arc. Not exactly sure what a plasma arc is. Any info would be great. Thanks.

hmm thanks but that just talked about what the current is doing. Already knew that but what is actually going on metalurgically? I need some in depth descriptions. Keep them coming.
