Selecting Weld Cable Sizes; Remote 14 Receptacle Rc14 Information - Miller PipePro 304 Owner's Manual

5-7. Selecting Weld Cable Sizes*

Weld Output
Terminals
Y Turn off power before
connecting to weld out-
put terminals.
Y Do not use worn, dam-
aged, undersized, or
poorly spliced cables.
This chart is a general guideline and may not suit all applications. If cable(s) overheat (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.
2
( ) = mm for metric use
***For distances longer than those shown in this guide, call a factory applications representative at 920-735-4505.
