5-7. Selecting Weld Cable Sizes*

Weld Output

Terminals

! Turn off power before connecting to weld output terminals.

! 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(s) overheat, 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.
( ) = mm2 for metric use	S-0007-F
