Grinding also removes oil from the mill finish metal surface.

My preference is to bead blast first, inspect for rolling stress lines/striations in the surface, if I see those, then grind.

I also wipe the surfaces with isopropyl alcohol, and wipe down the filler rod, too.

I tried acetone, but it leaves an oily residue.

do u have to clean for stick welding i know i dont

[kevincaron]

@6013welder. You should! Good metal prep is important for all kinds of welding. Welding dirty metal is like closing a zipper with your shirt tail caught in it. It will work but not as well as it should.

@jorgencream Can't say has I have ever seen anything that small. Course if you are a fabricator maybe you can make something up!

Hey Kevin

Sometimes I like to weld naked. Do you know if they make any face shields for my Johnson???
