*Chart is a guideline and may not suit all applications. If cable overheating occurs (normally you can smell it), 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 | |
***For distances longer than those shown in this guide, call a factory applications representative at |
