*This chart is a general 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
***Select weld cable size for pulsing application at peak amperage value.	S-0007-E−803 080
