OPERATION
13. WELDING TERMINALS SWITCH
In the WELD TERMINALS ON position, the output is
electrically hot all the time. In the REMOTELY CON-
TROLLED position, the output is controlled by a wire
feeder or amptrol device, and is electrically off until a
remote switch is depressed.
14. WIRE FEEDER VOLTMETER SWITCH:
Matches the polarity of the wire feeder voltmeter to the polari-
ty of the electrode.
15. 6 - PIN CONNECTOR
For attaching optional remote control equipment. Includes
auto-sensing remote control circuit.
16. 14 - PIN CONNECTOR
For attaching wire feeder control cables. Includes contactor
closure circuit, auto-sensing remote control circuit, and
120VAC and 42VAC power.
NOTE: When a wire feeder with a built in welding voltage con-
trol is connected to the 14-pin connector, do not connect any-
thing to the 6-pin connector.
7. WELD OUTPUT TERMINALS + AND –
These 1/2” - 13 studs with flange nuts provide welding con-
nection points for the electrode and work cables. For positive
polarity welding the electrode cable connects to the “+” termi-
nal and the work cable connects to this “–” terminal. For nega-
tive polarity welding the work cable connects to the “+” termi-
nal and the electrode cable connects to this “–” terminal.
AUXILIARY POWER CONTROLS
(Items 18-21)
18. 120/240 VAC SINGLE PHASE RECEPTACLE
This is a 120/240VAC (14-50R) receptacle that provides
240VAC or can be split for 120VAC single phase auxiliary
power. This receptacle has a 50 amp rating. Refer to the AUX-
ILIARY POWER RECEPTACLES section in the installation
chapter for further information about this receptacle. Also refer
to the AUXILIARY POWER OPERATION section later in this
chapter.
20. CIRCUIT BREAKERS
These circuit breakers provide separate overload
current protection for each 120V circuit at the 240V
single phase receptacle, each 120V single phase
receptacle, the 240V three phase receptacle, the
120VAC in the 14-Pin connector, the 42VAC in the
14-Pin connector and battery circuit overload protec-
tion.
21. 120VAC SINGLE PHASE RECEPTACLES
These two 120VAC (5-20R) receptacles with GFCI
protection provide 120VAC single phase for auxiliary
power. Each receptacle has a 20 amp total rating.
They are designed to protect the user from the haz-
ards of ground faults. When the GFCI has tripped
there will be no voltage available from the receptacle.
Refer to the AUXILIARY POWER RECEPTACLES
section in the installation chapter for further informa-
tion about these receptacles. Also refer to the AUX-
ILIARY POWER OPERATION section later in this
chapter.
22. GROUND STUD
Provides a connection point for connecting the
machine case to earth ground. Refer to “MACHINE
GROUNDING” in the Installation chapter for proper
machine grounding information.
