In this case of the lift-arc principle, the tungsten electrode is placed on the workpiece. This causes a short circuit.
A limited ignition current flows, ionises the gap and ignites the arc upon lifting.
Preparation: Connect TIG torch with gas valve at the –VE socket and feed in the argon gas over a separate
gas hose.
JÄCKLE ProPuls reduces tungsten inclusions during the contact ignition by means of a gentle rise in the welding
current. Thereby, less heat is introduced. The precise and quick control technology prevents inclusion and
additionally reduces undercut.
With an optional feature at the end of the welding process (raising the torch) the welding current is automatically
reduced. This reduces end craters by reducing the current gently.
Set the machine to the welding process TIG Lift Arc or TIG pulse Liftarc.
The desired welding current can be set.
Furthermore, the following parameters can be changed individually.
Slope up: Rise time from ignition to the main welding current
Slope down: Time for power to reduce before stopping
Stop voltage: Here, an individual voltage can be set to initiate shutdown
Pulse delta: Level of pulse current in % in relation to main current
Pulse balance: The balance of the pulse current (positive in relation to negative half-wave)
Pulse frequency: The frequency of the pulse current
Reference values for tungsten electrodes and the current carrying capacity / however always consult with
manufacturer specifications of the tungsten electrodes.

18.6 Welding sequences / changing between jobs
A welding sequences is a sequence of successively saved welding - JOBS. The welding jobs must be
consistently saved in the right order (exactly like individual points) and then separated from other welding points
with a space before and after the sequence.
If the sequence is fixed in this way, complex workpieces can be welded without interruption The sequence can
be called up again and is reproducible at any time.
