1 Arc Force (Dig) Control
Control increases SMAW short-circuit
amperage which allows the operator to use
a very short arc length without sticking the
electrode.
Set control at 0 for normal welding amper-
age. Turn clockwise to increase short-circuit
amperage.
2 Process Selector Switch
•CV-Sub-Arc Mode − For SAW (Sub-Arc)
applications requiring 1/16 in dia and
larger welding wire.
•CC Mode − For SMAW (Stick), GTAW
(TIG) − scratch start only, or SAW (Sub-
Arc) applications. NOTE: For best results,
use the Positive (+) High Inductance weld
output terminal (see Section 4-8) for
SMA W or GTA W welding.
•CV-FCAW Mode − For FCAW (Flux
Cored) or S AW (Sub-Arc) applications r e -
quiring 1/16 in dia or smaller welding wire.
3 Amperage/Voltage Adjustment Control
When Process Selector switch is in the
Constant Current position, turn control
clockwise to i n c r e a s e amperage. Read am-
perage from outer scale of control. When
Process Selector switch is in the Constant
Voltage position, turn control clockwise to in-
crease voltage. V oltmeter value changes as
control knob is turned. Control can be ad-
justed while welding.
4 Digital Meters
With Process Selector switch in the
Constant Current position, digital meters will
read 0 (zero) with contactor off. Digital me-
ters will display actual output voltage and
amperage with contactor on.
With Process Selector switch in the
Constant Voltage position, voltmeter dis-
plays preset voltage with contactor off. Volt-
meter and ammeter display actual output
voltage and amperage with contactor on.
5 Power Switch With Indicator Light
6 High Temperature Shutdown Light
7 Remote Amperage/Voltage Control
Switch
•For front panel control, place switch in
Panel position. With Control switch in the
Panel position and Process switch in the
CC position, Hot Start is energized for
ACA (Air Carbon Arc Gouging) and
SMA W (Stick) welding. When Hot Start is
energized, higher short-circuit amperage
helps arc starting. After arc starts, the Am-
perage/Voltage control setting determines
weld amperage.
•For remote control, place switch in Re-
mote position, and connect remote device
(see Section 4-10). NOTE: Hot Start is not
energized when switch is in the Remote
position.
8 Output Switch (Contactor)
For front panel control of output, place switch
in Panel position. For remote control of out-
put, place switch in Remote position, and
connect remote device (see
Section 4-10).
YWeld output studs are energized only
when Output switch is in On position,
or while welding.
YT urn Off power before connecting re-
mote device.
