Calibration settings are typically on the electrode label. You can also find a stick welding amperage chart online. Next, set up the polarity of the welding machine to match the electrode rod.

and welding gun. GMAW typically uses a constant voltage power source and direct current electrode positive (DCEP) polarity. There are three main modes of metal transfer used with GMAW: short circuit, ...

and gas-shielded flux-cored arc welding (FCAW-G). Both FCAW-S and FCAW-G use a consumable, tubular electrode that is filled with flux-materials. FCAW equipment includes a constant voltage power source ...
