1Positive (+) Weld Output Terminal

2Negative (−) Weld Output Terminal

For Direct Current Electrode Posi- tive (DCEP), connect work cable to

1Negative (−) terminal and electrode holder to Positive (+) terminal.

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

! Failure to properly connect weld cables may cause ex- cessive heat and start a fire, or damage your machine.

4Supplied Weld Output Terminal Nut

5Weld Cable Terminal

6Copper Bar

Remove supplied nut from weld output terminal. Slide weld cable terminal onto weld output terminal and secure with nut so that weld cable terminal is tight against cop- per bar. Do not place anything be- tween weld cable terminal and copper bar. Make sure that the surfaces of the weld cable termi- nal and copper bar are clean.

*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.
