do i need to remove the copper coating on the mild steel filler rods?
Reply:No, if you're speaking of the GTAW process or TIG, then NO. If the filler wire has been sitting around for a while, it's advisable to just wipe them off with some acetone, brake clean or other solvent.John - fabricator extraordinaire, car nut!- bleeding Miller blue! http://www.weldfabzone.com

Reply:Thoose rods are for O/A welding, i got a few. The copper helps prevent contamination of the filler rod. As for helping to draw the rod? No idea.
