*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.

( ) = mm2 for metric useS-0007-F

***For distances longer than those shown in this guide, call a factory applications representative at 920-735-4505.

5-7. Remote Receptacle Information

.Engine runs at weld speed (3000 or 3600 rpm) whenever a device connected to the remote receptacle is running.
