What classes are required before using the MIG? I have past experience with a MillerMatic Mig unit and was wondering if I need to take the safety class or if I need to also attend one of the beginning classes as well as the safety before I could use the MIG in the metal shop.
I was in a similar position as you, but went ahead and completed both classes with Lee. It was well worth the time and hassle. Requirements aside, I highly suggest taking them for your, everyone around you, and equipment safety. There are plenty classes on the schedule.
Part of the reason for taking the class is to learn what Metal Shop’s & the Makerspace rules are on usage of equipment, which is independent of skill level.
