TIG WELDING (TIG LIFT MODE)
The DC TIG welding requires a protective gas (argon).
Follow the steps below:
1. Connect the earth clamp to the positive socket (+).
2. Connect the torch to the negative socket (-), the DINSE connector and the gas connector.
3. Connect the gas pipe from the rear of the welder to the flowmeter of the gas cylinder
4. Select TIG mode  using the selector button, press until the TIG indicator illuminates.
5. Adjust the desired current (display) using the keys, according to the thickness of the metal
workpiece (30A / mm).
6. Set the gas flow on flowmeter.
7. To start :
b- Raise the electrode to
between 2 - 5 mm from the
workpiece.
8. When finished:
Release the trigger, downslope, post-gas
Adjustment of downslope
Function activation:
This function allows the user to adjust the time required at the end of
welding for the gradual decline in the welding current until the arc stops.
This function helps to avoid cracks and craters at end of welding. To activate
it, proceed as follows:
1- Press the selector button  for 3 seconds
2- The TIG indicator starts flashing and the display indicates the current
downslope time
3- Set the automatic arc downslope you wish from 0 to 10 sec (display)
using key.
4- Validate your choice pressing button . The TIG indicator remains
illuminated.
Recommended combinations / Electrode grinding

0.5-5 10-130 1.6 9.8 6-7
4-7 130-190 2.4 11 7-8
To optimise the welding process, it is recommended to grind the electrode prior to welding as described in
the diagram below:
