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.

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.
