TIG WELDING WITH “Lift” TYPE STRIKING
4a) Open the gas cylinder and flow regulator (8-14 l/min).
5a) Put the electrode at the point at which welding is to begin, put the TIG torch at an angle so that the edge
of the gas nozzle is not on top of the piece to be welded, keeping contact between the point of the
electrode and the piece to be welded (Image. 3-1).
6a) Press the torch button.
7a) The “Lift” function strikes the arc when the TIG torch electrode comes into contact with the work piece
and is then removed (Image 3-2)
8a) Carry out TIG welding (Image 3-3).
To end welding:
• Lift the torch slowly, at a certain point the welding current decreases, and then stop.
• The welding machine follows an automatic down slope along with extinguishing of the arc.
9a) When finished welding, remember to shut off the gas cylinder
TIG WELDING WITH HIGH FREQUENCY STRIKING (HF)
4b) Open the gas cylinder and flow regulator (8-14 l/min).
5b) Put the electrode at the point at which welding is to begin, put the TIG torch at an angle so that the
edge of the gas nozzle is not on top of the piece to be welded, keeping a 2-3 mm gap between the
point of the electrode and the piece to be welded (Image 4-1).
6b) Press the torch button.
7b) The voltaic arc strikes even without contact between the TIG torch electrode and the work
piece (Image 4-2).
8b) To continue welding put the torch back in its normal position (Image 4-3).
9b) When finished welding remember to shut off the gas cylinder.
IMPORTANT: The high frequency switches off automatically after switching on.
