In my downloaded Lincoln DC welder manual, they refer to the welding current controls in terms I am not sure of. They say when you want a "buttering" arc, to set the main current step dial, then use the fine current at the lower settings. It says 6010 is what you want a "buttering" arc for.
Then it says if you want a "digging" arc to do the opposite, to set the main current lower, then adjust the fine current to the upper settings on its dial.
I have not heard of these terms before. The 6010 was specifically cited in the paragraph on buttering, but no rod was mentioned in the "digging" paragraph. Would the "digging" setting be for 7018 or heavy iron powder coating rods?
I have welded for a long time, but have lost information on my grey matter hard drive here and there along the way. I'm having to relearn some of this. And then, anything you don't do for a while, you get rusty.
Thanks.
