Weld Output Terminals And Selecting Cable Sizes - Miller Electric SuitCase X-TREME 8 OS Owner's Manual

4-9. 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.

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 (AWG) is based on either a 4 volts or less drop or a current density of at least 300 circular mils per ampere.
