2.3.1 2T Normal Mode
In this mode, the torch trigger must remain depressed
for the welding output to be active. Press and hold
the torch trigger to activate the power source (weld).
Release the torch trigger switch to cease welding.
NOTE:
In this operation mode,the function of UP SLOPE and
DOWN SLOPE is not used!
2.3.2 4T Latch Mode
This mode of welding is mainly used for long weld
ing runs to reduce operator fatigue. In this mode
the operator can press and release the torch trig
ger and the output will remain active. To deactivate
the power source, the trigger switch must again be
depressed and realized, thus eliminating the need for
the operator to hold the torch trigger.
Note that when operating in GTAW (HF and LIFT
TIG modes), the power source will remain activated
until the selected down slope time has elapsed.
NOTE:
This Up Slope operates in (4T) TIG modes only and
is used to set the time for the weld current to ramp
up, after the torch trigger switch has been pressed
then released, from Initial Current to High or BASE
current.
