TIG WELDING
1) Press the Select Mode button (Fig. 2, #2) to switch on the TIG Weld Mode LED (Fig. 2, #3).
2) The display (Fig. 2, #8) will blink TIG for approximately two seconds.
3) The Slope Down Function Indicator LED (Fig. 2, #11) will illuminate.
4) Use the encoder (Fig. 2, #9) to regulate the welding current shown on the display (Fig. 2, #8).
5) You can select the slope down time by pressing the Function button (Fig. 2, #13) until the display (Fig.
2, #8) blinks SLo . Use the encoder (Fig. 2, #9) to select the slope down time desired. The slope down
regulation varies from 0.1 to 10 seconds. You can also turn off slope down by reducing the slope down
regulation to a minimum. Simply turn the encoder until the display reads OFF .
6) Pressing the Function button (Fig. 2, #13) again activates the pulse frequency mode. The Pulse Function
Indicator LED (Fig. 2, #12) will blink and the display will read P Fr . By turning the encoder (Fig. 2, #9),
you can vary the frequency value from 0.4Hz to 999Hz. The factory set the base current at 25% of the
welding current value. To exit out of the pulse frequency mode, hold down the Function button (Fig. 2,
#13) for approximately 2 seconds until the flashing P Fr disappears.
Procedure for TIG Welding with LIFT Start
Start Welding:
1) Bring the tip of the electrode (tungsten) into contact with the work piece.
2) Lift the torch from the side so as to move slightly away from the work piece and start the welding
process.
End Welding:
1) In TIG welding mode with the slope down function on, you can end your weld by regulating the
distance between the arc and the work piece.
2) With the slope down function turned off, the you must pull the arc away from the work piece to end the
welding process.
Fig. 3 below shows how you can lift the torch from the work piece to start the slope down process and end
welding.
