TIG welding with contact ignition
(without HF)
Start up
¨ Fit the torch with a tungsten electrode and a gas
nozzle suitable for the application (see instruction
leaflet of the torch).
¨ Connect and lock the ground cable to the socket B.
¨
Connect the gas hose to the pressure reducer of the
gas supply.
¨ Plug in the mains plug.
¨ Switch on the main switch ,
¨
Select by the TIG or pulsed TIG process; the
LED lights up.
¨
Select by the control mode or , the
corresponding LED lights up.
¨ Adjust the relevant welding parameters.
¨ Open the gas supply valve.
¨
Depress the trigger (and release it if 4-step mode).
¨
Adjust the gas flow with the setting screw of the
pressure regulator.
¨ Release the trigger (depress and release it if 4-step
mode).
Arc ignition
¨
Prior to depressing the trigger, place the electrode
tip on the weld at the point where the arc is to be
ignited. Tilt the torch backwards until the edge of the
gas nozzle rests on the workpiece, and pursue until
a gap of 2 to 3 mm is obtained. Hold the position
(Fig. 7a)
¨
Protect your eyes with a welding helmet.
¨
Depress the trigger; the gas starts flowing.
¨
Tilt the torch gently until the tip touches the
workpiece (Fig. 7b).
¨
The arc ignition occurs as soon as the electrode is
lifted off the surface while the torch is held in a
convenient position for welding (Fig. 7c).
¨
Proceed with welding.
