1. Welding Mode Switch: Controls the welding mode of the
machine:
Select Stick welding or Lift TIG welding.
• Stick (SMAW):
• Lift TIG (GTAW): When the mode switch is in the Lift TIG
position, the stick welding functions are disabled and the
machine is ready for Lift TIG welding. Lift TIG is a method of
starting a TIG weld by first pressing the TIG torch electrode on
the work piece in order to create a low current short circuit.
Then, the electrode is lifted from the work piece to start the
TIG arc.
2. Output Current Knob: Potentiometer used to set the output
current used during welding. Set the output according to the
type and size of electrode.
3. Thermal LED: This indicator will turn on when the machine is
overheated and the output has been disabled. This normally
occurs when the duty cycle of the machine has been
exceeded. Leave the machine on to allow the internal
components to cool. When the indicator turns off, normal
operation is again possible.
4. Input Power (Input Voltage) After the Power Switch is
turned on the LED will illuminate.
5. Negative Quick Disconnect: Negative output connector for
the welding circuit.
