The starting current time t-S specifies the duration of the starting-current phase I
s
.
IMPORTANT!The starting current time only applies in 2-step mode. In 4-step mode, the
duration of the starting-current phase I
s
is controlled using the torch trigger
Final current time

Factory setting OFF
The final current time t-E specifies the duration of the final current phase I
E
.
IMPORTANT!The final current time only applies in 2-step mode. In 4-step mode, the du-
ration of the final current phase I
E
is controlled with the torch trigger (see: "TIG operating
modes").
