4-5. 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.

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.
