12. 6 - PIN CONNECTOR (AMPHENOL)
The 6-pin amphenol located on the control panel
allows for connection of interfacing equipment.
13. WELD OUTPUT TERMINALS + AND -
These 1/2 - 13 studs with flange nuts provide welding
connection points for the electrode and work cables.
For positive polarity welding, the electrode cable con-
nects to the “+” terminal and the work cable connects
to this “-” terminal. For negative polarity welding, the
work cable connects to the “+” terminal and the elec-
trode cable connects to this “-” terminal.
AUXILIARY POWER CONTROLS
(Items 14 through 18 )
14. 120/240VAC RECEPTACLE
This is a 120/240VAC (14-50R) receptacle that
provides 240VAC. Or, it can be split for 120VAC sin-
gle-phase auxiliary power. This receptacle has a 50
amp rating. Refer to AUXILIARY POWER RECEP-
TACLES section in the Installation section for further
information about this receptacle. Also refer to the
AUXILIARY POWER OPERATION later in this section.
15. 50 AMP CIRCUIT BREAKERS
These circuit breakers provide separate overload
current protection for each 120V circuit at the 240V
receptacle.
16. 120VAC RECEPTACLES
These two 120VAC (5-20R) receptacles provide
120VAC for auxiliary power. Each receptacle has a 20
amp total rating. Refer to AUXILIARY POWER
RECEPTACLES in the Installation section for further
information about these receptacles. Also refer to the
AUXILIARY POWER OPERATION later in this section.
17. 20 AMP CIRCUIT BREAKERS
These circuit breakers provide separate overload cur-
rent protection for each 120V receptacle.
18. GROUND STUD
Provides a connection point for connecting the
machine case to earth ground for the safest grounding
procedure. Refer to MACHINE GROUNDING in the
Installation section for proper machine grounding infor-
mation.
19. 20 AMP CIRCUIT BREAKER
This circuit breaker provides overload protection for the
120 VAC circuit in the 14-pin amphenol.
20. VOLTMETER +/- SWITCH
Changes the polarity display on the wire feeder.
21. 10 AMP CIRCUIT BREAKER
This circuit breaker provides overload protection for the
42 VAC circuit in the 14-pin amphenol.
22. 14 - PIN CONNECTOR (AMPHENOL)
For quick connection of interfacing equipment.
23. ARC CONTROL
The ARC CONTROL potentiometer is active in two
modes: CC - STICK and CV - WIRE with different pur-
poses in each mode.
CC - STICK mode: In this mode, the ARC CONTROL
knob sets the short circuit current during stick welding.
Increasing the number from 1 to 10 increases the short
circuit current. This prevents sticking of the electrode to
the plate at low welding current settings. This also
increases spatter. It is recommended that the control
be set to the minimum number without electrode stick-
ing.
CV - WIRE mode: In this mode increasing the number
from 1 to 10 changes the arc from soft and washed in
to crisp and narrow. It acts as an inductance control.
The proper setting depends on the application and
operator preference.
In general, MIG welding performs best in the “SOFT”
range and Innershield in the “CRISP” range.
