Care and feeding of our Miller welder

I stopped by Miller’s booth at the PRI Trade show yesterday and grilled their engineers about welders. The welder we have is an IGBT based design and is pretty much a hoss. It is also the series of welder that is their primary product at this point. The main weakness that they mentioned was metal dust building up inside the case in “very harsh environments, like places with half an inch of aluminum dust on the floor.” Regardless, they recommended opening the thing up and blowing it out with shop air once a year or so. I don’t think anyone was really planning on doing this yet so I figured I’d mention it.

Nice catch, I don’t know if anybody else would have picked up on it.

Does anyone want to add some upkeep and other information to make the wiki page for the welder better?
