5-7. Connecting To Weld Output Terminals

1 Positive (+) Weld Output

Terminal

2 Negative (−) Weld Output

Terminal

For Direct Current Electrode Posi- tive (DCEP), connect work cable to Negative (−) terminal and electrode holder to Positive (+) terminal.

For Direct Current Electrode nega- tive (DCEN), reverse cable con- nections.

*This chart is a general guideline and may not suit all applications. If cable overheating occurs (normally you can smell it), 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

***For distances longer than those shown in this guide, call a factory applications representative at 920-735-4505.
