Amperage/Voltage Control - The amperage/voltage control
selects the desired amperage or open circuit voltage within the
entire range of the welding power source. Rotating this control in
a clockwise direction increases the amperage or voltage output.
The scale surrounding the control represents approximate
actual amperage (innerscale) or voltage (outerscale) values.
Hot Start Control -The Hot Start Control operates in the STICK
mode. The Hot Start time is approximately 0.06 seconds in STICK.
The current value is adjusted from 0 to 100 Amps over the determined
weld current set by the Amperage Control. Rotating the Control
clockwise increases Hot Start current.
Arc/Inductance Control - In the STICK welding (SMAW) mode,
this control provides a variation of short-circuit amperage. In the
MIG (CV) mode, this control functions as an inductance control,
allowing for the adjustment of the dynamic properties of the arc.
The zero (0) setting provides a minimum inductance and a fast-
responding arc. The 100 setting provides maximum inductance
and a slower-responding arc. As the inductance is increased,
the AMPERAGE/VOLTAGE control may need to be adjusted to
achieve the desired weld characteristics.
Process Selector Switch - The process selector switch allows
the operator to select the STICK welding (SMAW), LIFT TIG
(GTAW), or MIG (GMAW) process.
Warning Indicator - The Warning Indicator located on the front
panel will become activated under the following conditions:
• Input voltage is too low
• Input voltage is too high
• Thermal overload
AC Power Indicator - The AC Power indicator located on the
front panel lights when the PRIMARY POWER Switch is in the
ON position, indicating the unit is energized.
Amperage/Voltage Switch - This selector switch determines
the adjustment of amperage/voltage. In the PANEL position,
amperage/voltage is controlled by the front panel control. For
remote amperage/voltage control, set the switch in either the
REMOTE 14 or REMOTE 17 position, depending on which
remote control receptacle is used.
Output Contactor Switch - With the PRIMARY POWER Switch
ON, open circuit voltage will be present at the weld output
receptacle when the OUTPUT CONTACTOR SWITCH is in the
ON position. For remote contactor control, set the switch in either
the REMOTE 14 or REMOTE 17 position depending on which
remote control receptacle is used. Open circuit voltge will be
present at the weld output receptacles whenever the torch switch
or remote device is closed.
24V Circuit Breaker - Push to reset. Controls 24V power source
for wire feeders controlled through 14-Pin receptacle.
115V Circuit Breaker - Push to reset. Controls 115V power
source for wire feeders controlled through 14-Pin receptacle.
Amperage/Voltage Selector Switch - Selects digital meter
display of output amperage or voltage.
Preview Pushbutton Switch - Allows digital meter to be used
to set voltage (in MIG mode) or amperage (in TIG or STICK
modes) prior to welding.
