I'm welding 1/2 angle to a 1 inch steel tie rod with 7018 rod
what amperage and voltage should i be on?
---------------------------------------------------
1/8" 7018 usually run good on about 125 amps
for 7018 rods, you can convert the diameter of the rod to decimals and use that for your amperage.
.125" = 125 amps
3/32" rod = .094" = 94 amps
