I have a 225/125 AC/DC stick welder, and I have a quick question about using DC over AC. I've been using the machine mainly on DC+, but have noticed the max amperage on DC is 125a. Now, in AC, it will max out at 225a. My question is, will the capabilities of the machine (welding heavier gauge material) be greater on AC than DC considering the amperage max for each? In other words, what will be the difference in material thickness I can weld on 125a DC vs 225a AC? Thanks!
