TIG Comfort The "TIG Comfort Stop" parameter is only available with the TP 2500/3500 TIG
Stop parameter power source. On the TP 2500/3500 power source, the response at the end of
welding is the same as the response with the TIG Comfort Stop function deactiv-
ated.
IMPORTANT! The instructions for setting the TIG Comfort Stop parameter also
apply to the "TIG pulsed arc welding" process (TP 2500/3500 TIG only).
The TIG Comfort Stop parameter determines how high the torch must be tem-
porarily raised to trigger the TIG Comfort Stop function. If the welding process
is frequently stopped unintentionally, increase the value of the TIG-Comfort-
Stop parameter.

The purpose of the arc-force dynamic
parameter is to influence the short-cir-
cuit amperage at the moment of
droplet transfer.

If the rod electrode has a tendency to
stick, adjust the arc-force dynamic
parameter to a higher level.
Level 0 produces a particularly soft,
low-spatter arc. Level 4 or 5 produces
a particularly hard and stable arc.
Factory setting: Level 2
t (s)
The Cel characteristic parameter sets
the slope for the falling welding cur-
rent characteristic. When welding cel-
lulose electrodes, the characteristic
slope is the most important criterion
for the weld properties.
If the cellulose electrode has a tend-
ency to stick, adjust the characteristic
parameter to a higher level (flat char-
acteristic).
