WELDING CABLE AND POLARITIES
1. Lift the output terminal protective cover (Figure 12) on the
welder-generator to gain access to the welding output
terminals.
Figure 12. Protective Cover
2. Next, remove the wings nuts and flat washers that are
attached to the output terminals.
3. Place welder cables onto output terminals (post). Select
apporiate polarity depending on application. Reference

NOTICE
ALWAYS
attach a terminal ring on the end of the
welding cables.
NEVER
attach stranded or exposed
wires to the output terminals. This condition could cause
arcing which could start a fire.
4. Reinstall wing nuts and washers back onto output
terminals. Tighten wing nuts securely to prevent arcing.
WELDING CABLE SELECTION
The welding cable should be larger in size as it becomes
longer or its current becomes higher. Prepare a cable with
suitable size by referring to the table below.
Calculations for Table 9 are based on a voltage drop of 4
volts maximum.
Reference Table 10 for applicable electrode size.
NOTICE
NEVER
allow the terminal ends of the welding cables
to come in contact with each other or the frame of
the welder-generator. The possibility exits of creating
sparks which could ignite a fire causing damage to the
equipment and bodily harm.
