Ref. 803 410-B / 803 778-A

! Turn off power before connecting to weld output terminals.

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

Determine total cable length in weld circuit (both positive and negative cables combined) and maximum welding amperes. See Section 5-1to select proper

cable size.

1Positive (+) Weld Output Terminal

2Negative (−) Weld Output Terminal

Connect positive weld cable to Positive (+) weld terminal and negative (−) cable to Negative weld terminal.

3Weld Output Terminal

4Supplied Weld Output Terminal Nut

5Weld Cable Terminal

6 Copper 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 copper bar. Do not place anything between weld cable terminal and copper bar. Make sure that the surfaces of the weld cable terminal and copper bar are clean.
