OPERATION - TIG
Before starting any welding activity ensure that you have suitable eye protection and
protective clothing. Also take the necessary steps to protect any persons within the welding
area.
TIG operation steps
Select the downslope time setting function by
pressing the welding parameter selecting key and
set the downslope time.
Select the crater current setting function by pressing
the welding parameter selecting key and set the
pilot arc current.
Select the post flow time setting function by
pressing the welding parameter selecting key and
set the post flow time.
After the parameters are set appropriately, open the gas valve of the cylinder and adjust the gas
regulator to the desired flow value.
Keep the torch 2-4mm away from the work piece and then press the torch trigger, the solenoid valve will
operate, gas will flow and HF starts.
After arc is ignited, the HF discharge rustling disappears, the current rises up to the preset value and
welding can be carried out. After releasing the torch trigger, the current begins to decrease automatically
to the crater current value. Then, arc stops with gas kept flowing for the post flow time and welding ends.
Pulsed TIG
Select the pulsed TIG mode by pressing the welding mode selecting key.
Select the 2T mode by pressing the operation mode selecting key.
Proceed with the set up as for standard TIG. The welding current setting now becomes the peak welding
current of the pulse. The next step will allow setting of the base current. This is only allowed when the
pulse mode is selected.
