What Amps Should 7018 Welding Rods Be At?

In turn, the rod diameter you use depends on the thickness of the steel you are welding. In general, the 7018 rod is used with currents up to 225 amps. A rule of thumb is to use 30 amps of current per 1/32 inch of rod diameter. That would mean using 90 amps of current on a rod that is 3/32-inch in diameter.
