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
30 m (100 ft) from the workpiece, the total cable length in the weld circuit is 60 m (2 cables x 30 m). Use the 60 m (200 ft) column to determine cable
size.
!
Turn off power be-
fore connecting to
weld output termi-
nals.
!
Do not use worn,
damaged, under-
sized, or poorly
spliced cables.

This chart is a general guideline and may not suit all applications. If cable overheats, use next size larger cable.
**Weld cable size is based on either a 4 volts or less drop or a current density of at least 300 circular mils per ampere.
***For distances longer than those shown in this guide, call a factory applications representative.
