7. WELD TERMINALS ON SWITCH- Output is enabled
when in the ON position. Output is remotely controlled when in
the REMOTE position. This control is not active in ArcLink®
modes.
8. DOOR LATCH
9. ARC CONTROL - The ARC CONTROL knob is active in the
CV-WIRE and CC-STICK modes, and has different functions in
these modes. This control is not active in the TOUCH START TIG
mode or in ArcLink® mode.
CC-STICK mode: In this mode, the ARC CONTROL knob sets the
short circuit current (arc-force) during stick welding. Increasing
the number from -10(Soft) to +10(Crisp) increases the short
circuit current and prevents sticking of the electrode to the plate
while welding.
This can also increase spatter. It is recommended that the ARC
CONTROL be set to the minimum number without electrode
sticking. Start with a setting at 0.
DOWNHILL PIPE mode: In this mode, the ARC CONTROL knob
sets the short circuit current (arc-force) during stick welding to
adjust for a soft or a more forceful digging arc (Crisp).
Increasing the number from -10(Soft) to +10(Crisp) increases
the short circuit current which results in a more forceful digging
arc. Typically a forceful digging arc is preferred for root and hot
passes. A softer arc is preferred for fill and cap passes where
weld puddle control and deposition ("stacking" of iron) are key
to fast travel speeds. It is recommended that the ARC CONTROL

11. 42V / 115V WIRE FEEDER VOLTAGE SWITCH -
ARC LINK
Toggles output of 14-pin connector to voltage requirement of
Wire Feeder. (Located above 14-pin connector.)
11a. 42V and 115V WIRE FEEDER BREAKERS
12. 5-PIN CONNECTOR - For attaching an ArcLink® Wire
Feeder control cable.
13. 12-PIN CONNECTOR - For attaching optional remote
control equipment. The K2909-1 (12-pin to 6-pin) adapter
cable is included for attaching to accessories requiring the 6-
pin connector.
14. 14-PIN CONNECTOR - For attaching wire feeder control
cables. Includes contactor closure circuit, work senselead
remote control circuit, and 120VAC and 42VAC power.
15. WELD OUTPUT TERMINALS "+" POSITIVE AND
"-" NEGATIVE - 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 "+" positive terminal and the work cable con-
nects to this "-" negative terminal. For negative polarity weld-
ing the work cable connects to the "+" positive terminal and
the electrode cable connects to this "-" negative terminal.
16. LOCAL/REMOTE SWITCH - In the LOCAL position,
machine output control is set by the Output Control knob on
the front of the machine. In the REMOTE position, the
machine output control is set by the remote inputs. This con-
trol is not active in ArcLink® modes.
17. POLARITY SWITCH - Matches the polarity of the wire
feeder voltmeter to the polarity of the electrode.
18. 20A 120V AUXILIARY BREAKER
19. 50A 240V 3 PHASE BREAKER
20. BATTERY 20A BREAKER
21. 240VAC THREE PHASE RECEPTACLE - This is a
240VAC (15-50R) receptacle that provides 240VAC three
phase auxiliary power. This receptacle has a 50 amp rating.
22. 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 chap-
ter for further information about this receptacle. Also refer to
the AUXILIARY POWER OPERATION section later in this chap-
ter.
23. 10A 42V/40V ARCLINK BREAKERS
24. 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 protection.
25. GROUND STUD - Provides a connection point for con-
necting the machine case to earth ground. Refer to "MACHINE
GROUNDING" in the Installation chapter for proper machine
grounding information.
26. Status LED
(See Table B.1)
The status LED indicates system status. Normal operation is a
steady green light.
Note: During normal power-up, the LED may flash red and/or
green as the equipment performs self tests.
