It is sometimes called "stick welding", because of the filler metal. The filler metal is in the form of heavy wire coated with flux.
Usually the type of electrode matches the type of stainless being welded.
arc efficiency=heat developed at anode/total heat developed
Since this process of welding makes use of a consumable electrode coated in flux, there may be isolated inclusions forming on the weld bead. This may result in a poorer quality of the weld bead and...
It depends on the resistance to the current flow
