function
The "TIG Comfort Stop" function (TCS) is only available with the TP 2500/3500 TIG power
source. The TIG-Comfort-Stop function is deactivated as standard. Activating and setting
the TIG Comfort Stop function is described in the "The Setup menu" section.
If the TIG Comfort Stop function is deactivated, end crater filling through current decrease
or gas shielding of the end crater does not occur. To finish welding lift the torch away from
the workpiece until the arc goes out.
To finish welding with activated TCS function, proceed as follows:
1.
Welding
2.
During welding, raise the welding torch
-
The arc length is increased significantly
3.
Lower the welding torch
-
The arc length is decreased significantly
-
This triggers the TIG Comfort Stop function
4.
Keep the welding torch at the same height
-
The welding current continuously decreases until it reaches the minimum welding
current (10 A) (downslope)
-
The minimum welding current is held constant for 0.2 seconds
-
Arc goes out
5.
Wait for the gas post-flow time to finish, and lift the torch off the workpiece
