2.3.2 4T Latch Mode
This mode of welding is mainly used for long welding runs to reduce operator fatigue. In this mode the
operator can press and release the torch trigger 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.
