The Power Feed
™
/ Power Wave
®
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
connect 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. While TIG welding, the right encoder can only turn output on
and off in 2-step only. Turning the right encoder while 4-step TIG is selected will cause a message to be dis-
played indicating that on/off output control is only available in 2-step TIG.

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.
