Setting Polarity for Welding Type

WARNING! Always turn welder off and disconnect it from it’s electrical supply before opening the case or performing any adjustment, including the following pro- cedure.

1.Set for Electrode Positive (DCEP) for gas welding with solid-core wire

-Red electrode cable (C) to positive termi- nal (A);

-Black ground cable (D) to negative termi- nal (B).

See illustration, top right initial Setup.

2.To reverse polarity 1. Remove the nuts.

2. Change the places of the cables (C, D).

3. Replace and tighten the nuts.

When connecting the weld output terminals, you should keep the square washers in place.

3.Set for Electrode Negative (DCEN) for gasless flux core wire:

-Red electrode cable (C) to negative termi- nal (B);.

-Black ground cable (D) to positive terminal

(A).

(See illustration, bottom right.)

4.Always read and follow wire manufacturer’s recommended polarity.
