GTAW (TIG) WELDING
The Power Feed / PowerWave system is excellent for Touch Start TIG welding.
The system supports both TIG torches with or without gas control valves. TIG torches with gas control valves con-
nect directly to the gas flow regulator. For TIG torches without gas control valves, connect the output gas hose on
the Power Feed 10M Single Wire Feeder.

No Foot/Hand Amptrol
1. Adjust the arc amperage with the left knob
on the display panel.
2. Turn the right knob on the display panel
until the Output Control is ON. Gas will
start to flow.
3. Touch the tungsten to the work piece.
4. Lift the tungsten to create an arc and weld.
5. Stop welding by turning the Output Control
to OFF, or by pulling away the tungsten
from the work.
6. Gas flow will continue for a short time and
then shut-off.
1. Adjust the arc amperage with the left knob
on the display panel.
2. Turn the right knob on the display panel
until the Output Control is ON.
3. Open the gas valve on the TIG torch.
4. Touch the tungsten to the work piece.
5. Lift the tungsten to create an arc and weld.
6. Stop welding by turning the Output Control
to OFF, or by pulling away the tungsten
from the work.
7. Close the gas valve on the TIG torch.
With Foot/Hand Amptrol
1. Adjust the maximum arc amperage with
the left knob on the display panel.
2. Touch the tungsten to the work piece.
3. Press the foot pedal or slide the hand amp-
trol a slight amount. Gas will start to flow.
4. Lift the tungsten to create an arc.
5. Regulate the arc current with the foot pedal
or hand amptrol.
6. Stop welding by releasing the foot pedal or
hand amptrol, or by pulling the tungsten
away from the work.
