I have a Lincoln Electric AC-225 stick welder. The manual isn't exactly clear about this, so I figured I would ask to be sure. Is it safe to turn the "dial" for the amperage WHILE the welder is on? Not while I am actually trying to weld something -- I mean PHYSICALLY in the process of it. I have been turning the unit off to change the amperage, and this just seems to be more work than required. Is it necessary to shut the unit off before changing the dial to a different amperage?
