Almost all electrodes have a series of numbers to tell #1 what the tensile strength of the weld will be, #2 what electrical current to use, #3 what position/s it can be used in (ie: flat, vertical etc.) Ex. E - 7018. E = electrode, 70 = 70,000 lbs tensile strength, 1 = all positions, 18 = AC or DC reverse polarity current. (welding lead +)

a stick welder needs to replace his electrode regularly and the flux coating is on the outside while a tig machine constantly feeds the wire and the flux is produced by a filler gas

i don't know please give me the answer
The wire feed welder is a MIG welder.
how do you calculate welding electrode consumption
