For Stick welding Direct Current Electrode Positive (DCEP), con-

2 nect work cable to (–) terminal and electrode holder cable to (+) terminal.

For Direct Current Electrode Nega- tive (DCEN), reverse cable connections.

If equipped with optional polarity switch, connect electrode holder

Left Sidecable to Electrode (–) terminal and work cable to Work (+) terminal.

For MIG and FCAW welding with CV option, connect work cable to (–) terminal and wire feeder cable to

(+) terminal

Close door.

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. Contact your dis-

tributor for the mm2 equivalent weld cable sizes. S-0007-E
