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 Weld Current.
