Selecting Weld Cable Sizes; Remote Receptacle Information - Miller Electric 301 G, DC Owner's Manual

5-8. Selecting Weld Cable Sizes*

Weld Output
Terminals
Y Stop engine 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 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.
2
( ) = mm for metric use
***For distances longer than those shown in this guide, call a factory applications representative at 920-735-4505.

A 24 volts ac.
B Contact closure to A completes 24 volt ac contac-
tor control circuit and keeps engine at Run speed
in all modes. Protected by circuit breaker CB5.
I 115 volts ac. Protected by fuse F2.
J Contact closure to I completes 115 volts ac
contactor control circuit.
C 0 to +10 volts dc output to remote control in Stick
and TIG modes. +10 volts dc output to remote
control in Wire mode.
D Remote control circuit common.
E 0 to +10 volts dc input command signal from
remote control. Voltage is dependent on front pan-
el Voltage/Amperage control setting.
G Circuit common for 24 and 115 volts ac circuits.
GND GND
K Chassis common.
