SECTION 3 – OPERATION
3-1. Controls
1 Arc Force (Dig) Control
For SMAW, control increases short-circuit
amperage which allows the operator to use
a very short arc length without sticking the
electrode.
Set control at 0 for GTAW. When set at 0
(zero), short circuit amperage at low arc volt-
age is the same as normal welding amper-
age.
2 Amperage/Voltage Adjustment Control
For AC or DC CC welding, such as GTAW
and SMAW welding, adjust control accord-
ing to amperage (A) scale. For GMAW and
FCAW welding, adjust control according to
voltage (V) scale.
3 Power Switch
4 Output Selector Switch
5 Amperage/Voltage Control Switch
Switch selects front panel or remote amper-
age/voltage control.
For remote amperage/voltage control, front
panel control setting is the maximum output
available. For example: If front panel control
is set to 200 A, the range available at the
remote amperage control is 0 to 200 A.
6 Output (Contactor) Switch
Switch selects front panel or remote output
control.
Y Weld output terminals are energized
when Output (Contactor) switch is
On and Power is On.
7 Ammeter (Optional)
8 Voltmeter (Optional)
