The „TIG-Comfort-Stop" parameter is only available with the TP 2500 TIG power source.
TIG-Comfort-
Stop parameter On the TP 2500 power source, the behaviour at the end of welding corresponds to the
behaviour with the TIG-Comfort-Stop function deactivated.
Important! The setting of the TIG-Comfort-Stop parameter also applies to the „TIG
pulsed arc welding" process (TP 2500 TIG only).
The TIG-Comfort-Stop parameter determines how high the torch must be temporarily
raised to trigger the TIG-Comfort-Stop function. If the welding process frequently stops
unintentionally, increase the value of the TIG-Comfort-Stop parameter.

The purpose of the arc-force dynamic
parameter is to influence the short-circuit
current at the moment of droplet transfer.
If the rod electrode has a tendency to
stick, adjust the arc-force dynamic para-
meter to a higher level.
Level 0 produces an especially soft and
low-spatter arc.

Level 4 or 5 produces an especially hard
and stable arc.

The CEL characteristic parameter sets the
slope for the falling welding current cha-
racteristic. When welding cellulose elec-
trodes, the characteristic slope is the most
important criterion for the welding proper-
ties.
If the cellulose electrode has a tendency
to stick, adjust the characteristic parame-
ter to a higher level (flat characteristic).
