1. Pulse function-Pressing this button enables the
TIG current pulse functions.
2. Scroll Buttons-used to select the parameter to
be set. The LED's show which function is being
adjusted on the weld sequence graph.
3. Digital LED display-Welding amperage and
parameter values are displayed in this win-
dow. Internal warnings such as over tempera-
ture, primary input current too high applied are
signaled to the operator by a warning sound
and error message on the screen.
4. Control knob-allows the operator to adjust the
output amperage within the entire range of the
power source, also used to set each parameter
value. Pushing the knob inward displays the
actual welding voltage.
5. Process Button-This button selects between
STICK, Lift or HF TIG mode.
6. 8 pin remote control receptacle for connecting
remote device.
7. TIG Mode Functions-Pressing this button
scrolls through the output TIG function modes
(Standard, Slope, Slope w/repeat, Spot).
8. Save/Load Button-by using the Save & Load
buttons the operator can easily save up to 5
welding parameter program.
