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.
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.
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.

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.)
