13. Spot indicator light
This light will illuminate when the power source is in GTAW SPOT welding mode.
14. Tiptronic indicator light (Refer to Section 3.12)
This light will illuminate when the power source is in TIPTRONIC welding mode and a saved job has been loaded.
15 4T (latch) indicator light
This light will illuminate when the power source is in GTAW 4T welding mode.
This mode of welding is mainly used for long welding runs to reduce operator fatigue. In this mode the operator can press and release
the torch trigger and the output will remain active. To deactivate the power source, the trigger switch must again be depressed and
released, thus eliminating the need for the operator to hold the torch trigger.
Note that when operating in GTAW (TIG mode), the power source will remain activated until the selected downslope time has elapsed.
16. 2T (normal) indicator light
This light will illuminate when the power source is in GTAW 2T welding mode.
In this mode, the torch trigger must remain depressed for the welding output to be active. Press and hold the torch trigger to activate
the power source (weld). Release the torch trigger switch to cease welding.
17. Welding Type Button
Press the TYPE button to select the Welding Type mode, i.e. current mode. Selects the welding current type DC, AC with/without HF
ignition.
In SMAW (Stick) mode, the available modes are Electrode DC-, Electrode DC+.
In GTAW (Tig) mode, the available modes are Electrode DC-, HF Electrode DC-, AC and HF AC.
18. HF (high frequency) indicator light
This light will illuminate when the power source is in GTAW 2T or 4T HF welding mode.
19. Electrode Negative indicator light
This light will illuminate when the power source is in Electrode Negative welding mode on the top welding terminal. (DC Output)
20. Electrode Positive indicator light
This light will illuminate when the power source is in Electrode Positive welding mode on the top welding terminal. (DC Output)
21. Electrode AC indicator light (only for AC/DC)
This light will illuminate when the power source is in Electrode AC welding mode on the top welding terminal. (AC Output)
22. BACK Welding Parameter Button
Press the BACK welding parameter button to scroll left through the available welding parameters.
23. FORWARD Welding Parameter Button
Press the FORWARD welding parameter button to scroll right through the available welding parameters.
24. Multi Function Control
Turn the MULTI FUNCTION CONTROL to adjust the available welding parameters.
When not welding, the Multi Function Control is used to adjust all welding parameters, including welding amps. A short press on the
Scroll Left or Scroll Right button will save the welding parameter value, then increment / decrement to the next available welding
parameter. The welding parameter LED will illuminate and the Multi Function Control will then adjust the selected welding parameter.
The parameter code and parameter value are shown on the meters and the LED's next to the meter indicate if the parameter is Amps,
Seconds, Inches, %, kHz or Hz.
During welding, adjustment of the Multi Function Control will adjust the selected parameter.
