Downslope:
The downslope is dependent upon the welding amperage that has been selected, and
cannot be adjusted.
-
-
Example: Where an average (i.e. medium) welding amperage of 70 A has been selec-
ted, the downslope will be 1.5 seconds long.
Gas post-flow time:
The gas post-flow time is dependent upon the welding amperage that has been selec-
ted, and cannot be adjusted.
-
-
Example: Where an average (i.e. medium) welding amperage of 70 A has been selec-
ted, the gas post-flow time will be 7.5 seconds long.
The diagram below illustrates the chronology of the welding current and the sequence
of the gas-flow when the TIG Comfort Stop function is active:
(1) Welding (2) Raise torch
