The 4T function in TIG mode acts similarly, but in conjunction with the down slope timer. As the torch
trigger is pressed for the second time, the trigger should be held in until the downslope timer completes its
cycle. The trigger may then be released to end the arc. Releasing before the down slope is finished will
terminate the arc immediately.

MIG Volt / TIG Down Slope / MMA Arc Force Control / MIG TIG post flow
In each mode the function of the control changes.
In MIG mode, the control is used to adjust the arc voltage (power)
While in TIG mode it functions to adjust the down slope of the arc current.
In Stick mode, the control is used to vary the automatic arc force current response. When used for stick
welding the arc force is also known as “dig”, the current is increased as the volts fall off due to a short arc
length. This helps maintain the arc by providing more power.
