—
Green:
Output current is too high or the
welder has failed.
—
Red:
Input current is incorrect.
C. Output Current Dial:
Adjust this control for
the correct welding output current (0–130A).
D. Upslope Current Dial:
Use this dial to con-
trol the amount of time (0–5 seconds) the
welding current takes to reach the selected
output current.
E. Downslope Current Dial:
Use this dial to
control the amount of time (0–5 seconds) the
welding current decreases from the selected
output current to
OFF
.
F. Post Flow Time Dial:
This knob will control
the amount of time (0–10 seconds) gas will
flow through the TIG torch after the welding
arc is shut off.
G. Pulse Frequency:

the torch thumb switch.
2.
Gas flows for 0.5 seconds to purge the
torch line of air.
3.
The welding current starts with a preset
upslope time of 0.2 seconds from the pre-
set starting current of 15A to the selected
output current
4.
Release the thumb switch to end the
welding sequence.
5.
The welding current decreases from the
selected output current to the preset fin-
ish current over the preset downslope
time, then the welding current shuts off.
6.
The shielding gas continues to flow for
the post flow time selected.
NOTICE
Always keep the power
ON
to the welder
after completing the welding operation to
let the welder fan cool the welder down. To
avoid damage to your welder, never shut
the power
OFF
before the welder enclosure
is completely cool to the touch.
