2.3 Trigger Mode Control Button (HF TIG and LIFT TIG Mode only)
The trigger mode control is used to switch the functionality of the torch trigger between 2T (normal),
and 4T (latch mode).
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 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
