6-2. Interface Operation Description
Power Switch Use switch to turn unit and indicator light On/Off.
VRD Indicator Light When the unit is configured for low open circuit voltage, this indicator light will illuminate.
High Temperature
Shutdown Light When unit is first energized this indicator light illuminates for approximately 1 second to provide visual confirmation
that the light is functioning properly. If unit overheats or is operated at an over duty cycle condition, this light will illu-
minate and output will stop (see Section 4-7).
Output Indicator Light When unit is first energized this indicator light Illuminates for approximately 1 second to provide visual confirmation
that the light is functioning properly and then illuminates continuously.
Amps Display This display illuminates and shows amperage for either TIG or stick welding process. Measured amperage just prior
to the end of a welding operation will appear on the display for three seconds after welding operation.
Amperage Adjustment
Buttons Use these buttons to set the desired amperage setting for either TIG or stick welding process.
TIG Process Select Press and release this button to activate the TIG welding process. Use the amperage adjustment buttons to set the
amperage to the appropriate welding setting.
Lift-Arc
™
Indicator
Light
This light will illuminate when the TIG process is selected.
Arc Control Select Press until the desired ARC Control setting indicator light is selected (STIFF or SOFT).
Arc Control Indicator
Light The indicator light for the active ARC Control setting will illuminate when the ARC Control select button is pressed
while in the STICK mode.
STICK Process Select Press and release this button to activate the STICK welding process controls and switch between electrode types
(EXX10 or EXX18). Press until the desired electrode type is selected. The electrode indicator light of the desired
electrode type will illuminate when selected. Use the amperage adjustment buttons to set the amperage to the ap-
propriate welding setting.
Electrode Indicator
Light The indicator light for the active STICK electrode type will be illuminated when in the STICK mode.

With Stick selected, start arc as follows:
1 Electrode
2 Workpiece
3 Arc
Drag electrode across workpiece like striking
a match; lift electrode slightly after touching
work. If arc goes out electrode was lifted to
high. If electrode sticks to workpiece, use a
quick twist to free it.
VRD Model Only: Normal open-circuit volt-
age is not present before electrode touches
workpiece; only a low sensing voltage is
present between electrode and workpiece.
This allows electrode to touch workpiece
without overheating, sticking, or getting
contaminated.
