1 Remote Receptacle RC4
Connect optional remote voltage/
amperage (V/A) control to RC4
(see Section 5-11).
Use receptacle to connect remote
control or wire feeder.
When a remote voltage/amperage
control is connected to the Remote
receptacle, the Auto Sense Re-
mote feature automatically
switches voltage/amperage con-
trol to the remote control (see Sec-
tions 5-11 and 6-3).
With remote voltage/amperage
control connected, weld output in
CC mode is determined by a com-
bination of front panel and remote
control voltage/amperage settings.
In CV mode, weld output is con-
trolled through remote control only.
If no remote voltage/amperage
control is connected to the Remote
receptacle, the front panel Voltage/
Amperage control adjusts voltage
and amperage.

Engine runs at weld/power
speed in Wire mode whenever
a device connected to the re-
mote receptacle makes clo-
sure between pins A and B. In
all other modes, the engine
runs at idle speed until a load is
applied.
