I taught myself how to weld with 6013, 7014, and 7018 but yesterday i picked up some 6011s and am having trouble maintaining an arc. it is almost like im snuffing out the arc but i dont think i am. i am keeping the same tight arc length that i do with the other electrodes. I am using the whip and pause technique. Is it normal for 6011 to to be kinda temperamental? Or am i not feeding the rod in fast enough? Any help will be greatly appreciated.
