Metal cleaning and prep for welding
 

What do you guys use to clean off any rust or paint or seam sealer before welding in panels? DA and 80 grit?

wire wheel, grinder,blasting,whatever works better in certain situations

^^^^^^^^^ What Stefan said -- basically -- whatever works.... I've used dental picks.... screwdrivers...

IF you use wire wheels == PLEASE wear eye protection..... those things fly off with some serious velocity!

I know it's probably not typically used but DO NOT use a chlorinated brake cleaner and weld with anything using argon. The combination produces phosgene gas (which is far worse than what comes out of me after a Klondike bar).

Most everyone probably knows by now but just in case.
