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, DOWNHILL PIPE or
CV-WIRE modes and when a remote control is connected to the
6-Pin or 14-Pin Connector, the auto-sensing 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 connected to the 14-Pin Connector, the auto-
sensing circuit automatically 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: (Optional Kit)
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 display 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 display 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 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
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 electrically
hot all the time. In the REMOTELY CONTROLLED position, 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 polarity 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 control
is connected to the 14-pin connector, do not connect anything to
the 6-pin connector.
18. 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 connects to the “+” terminal and the
work cable connects to this “-” terminal. For negative polarity
welding the work cable connects to the “+” terminal and the
electrode cable connects to this “-” terminal.
AUXILIARY POWER CONTROLS
(Items 19-22)
19. 120/240 VAC 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 AUXILIARY 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.
