5-2. Weld Output Terminals And Selecting Cable Sizes
NOTICE − The Total Cable Length in Weld Circuit (see table below) is the combined length of both weld cables. For example, if the power source is
100 ft (30 m) from the workpiece, the total cable length in the weld circuit is 200 ft (2 cables x 100 ft). Use the 200 ft (60 m) column to determine cable
size.

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.

5-3. Connecting Weld Output Cables
803778-B
!
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 ma-
chine.
.
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.

3 Weld Output Terminal
4 Supplied Weld Output Terminal Nut
5 Weld Cable Terminal
6 Copper Bar
Remove supplied nut from weld output ter-
minal. Slide weld cable terminal onto weld
output terminal and secure with nut so that
weld cable terminal is tight against copper
bar.
