Welding Amperage For Metal Thickness. The larger filler rod cools the weld pool more than the smaller rod so you might add about 5 amps if using 16mm filler rod. 16 mm 30 to 120 amps.
The chart tells you what amperage to use for what thickness and even tells you what maximum thickness your welder can accommodate based on the amps. You will need to set the amps much higher for the bigger rods. The specific amperage to be used depends primarily on the diameter of the electrode.
So in this article Im going to share a few examples to help you out.
That size will be determined by the thickness of the metal that will be welded and the welding current. It can be used on thinner material if the tip is kept very sharp. That size will be determined by the thickness of the metal that will be welded and the welding current. Whereas a 532 diameter electrode can weld optimally at up to 220 amps.
