Getting the most from your machine

For wire size Multiply by Ex. using 1/8 inch (125 amps)
.023 inch 3.5 inches per amp 3.5 x 125 = 437.5 ipm
.030 inch 2 inches per amp 2 x 125 = 250 ipm
.035 inch 1.6 inches per amp 1.6 x 125 = 200 ipm
.045 inch 1 inch per amp 1 x 125 = 125 ipm

Beside above, how thick can a 150 amp welder weld? Welding Buyer's Guide

Maximum Amps 90 amp 150 amp
Max Steel Thickness (butt weld) 2.0mm 4mm
Max Steel Thickness (with V and root gap) 3.0mm 6mm

Also asked, how do I know what amp to weld at?

Current setting The correct current, or amperage, setting primarily depends on the diameter and type of electrode selected. For example, a 1/8-inch 6010 rod runs well from 75 to 125 amps, while a 5/32-inch 7018 rod welds at currents up to 220 amps. The side of the electrode box usually indicates operating ranges.

How many amps does it take to weld a 3/16 Steel?

With 3/16" metal, I would start at 100-110 amps since 6013 does not penetrate like 6011.
