For MIG welding, connect work cable

 

 

to Negative (−) terminal and wire

 

 

feeder cable to Wire (CV) terminal.

 

 

For Stick/TIG welding, connect work

 

 

cable to Negative (−) terminal and

 

 

electrode holder cable to Stick/TIG

 

 

(CC) terminal.

*This chart is a general guideline and may not suit all applications. If cable overheats, use next size larger cable.

**Weld cable size (AWG) is based on either a 4 volts or less drop or a current density of at least 300 circular mils per ampere.

 

( ) = mm2 for metric use
