WELDING CONTROLS (Items 10 through 19)
10. OUTPUT CONTROL:
The OUTPUT dial is used to preset the
output voltage or current as displayed on the digital meters
for the four welding modes. When in the CC-STICK, DOWN-
HILL PIPE or CV-WIRE modes and when a remote control is
connected to the 6-Pin or 14-Pin Connector, the auto-sens-
ing circuit automatically switches the OUTPUT CONTROL
from control at the welder to the remote control. In the CV-
WIRE mode, when the wire feeder control cable is connect-
ed to the 14-Pin Connector, the auto-sensing circuit auto-
matically makes OUTPUT CONTROL inactive and the wire
feeder voltage control active.
When in the TOUCH START TIG mode and when a Amptrol is
connected to the 6-Pin Connector, the OUTPUT dial is used to
set the maximum current range of the CURRENT CONTROL
of the Amptrol.
11. DIGITAL OUTPUT METERS:
The digital meters allow the output voltage (CV-WIRE mode)
or current (CC-STICK, DOWNHILL PIPE and TIG modes) to
be set prior to welding using the OUTPUT control knob.
During welding, the meters display the actual output voltage
(VOLTS) and current (AMPS). A memory feature holds the dis-
play of both meters on the seven seconds after welding is
stopped. This allows the operator to read the actual current
and voltage just prior to when welding was ceased. While the
display is being held the left-most decimal point in each dis-
play will be flashing. The accuracy of the meters is ± 3%.
12. WELD MODE SELECTOR SWITCH:
(Provides four selectable welding modes)
CV-WIRE
DOWNHILL PIPE
CC-STICK
TOUCH START TIG
13. ARC CONTROL:
The ARC CONTROL WIRE/STICK knob is active in the WIRE
and STICK modes, and has different functions in these modes.
This control is not active in the TIG 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 weld-
ing 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 CON-
TROL be set initially at 0.
CV-WIRE mode: In this mode, turning the ARC CONTROL
knob from -10(soft) to +10(crisp) changes the arc from soft
and washed-in to crisp and narrow. It acts as an
inductance/pinch control. The proper setting depends on the
procedure and operator preference. Start with a setting of 0.
14. WELDING TERMINALS SWITCH
In the WELD TERMINALS ON position, the output is electri-
cally hot all the time. In the REMOTELY CONTROLLED posi-
tion, the output is controlled by a wire feeder or amptrol device,
and is electrically off until a remote switch is depressed.
15. WIRE FEEDER VOLTMETER SWITCH:
Matches the polarity of the wire feeder voltmeter to the polari-
ty of the electrode.
16. 6 - PIN CONNECTOR
For attaching optional remote control equipment. Includes
auto-sensing remote control circuit.
17. 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.
18. WELD OUTPUT TER 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 19-23)
19. 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.
