NOTE: Male Welding terminals have been included with your generator purchase.  Please use 
the correct gauge welding cable by referencing the chart on page 33 (not included).

Connect positive terminal

Connect negative terminal

Adjust current

Plug in the positive (red) welding terminal to the red output 

terminal on the front panel.

Plug in the negative (black) welding terminal to the black

Polarity Selection  

The welding terminals are labeled “+” (positive) and “-” (negative). Changing the polarity of the 

cables will affect the weld. The correct polarity selection is dependent on the type of electrode you 

are using and the type of material you are welding; refer to the electrode manufacturer’s recom-

mendations for best results. 

For straight polarity, attach the electrode cable to the negative terminal, and attach the ground 

cable to the positive terminal. To reverse polarity, reverse the cables.
