4.4 Trigger Mode Selection
1. Press Trigger Mode Selection Button until the desired indicator light is lit.
NOTE: Trigger mode selection only applies to TIG welding.

4.4.1 2t (Standard Trigger)
2T stands for Two Touch or ‘Standard Trigger’ mode. In this mode the trigger button is pressed and held
on to start welding, when the trigger button is released, the welding stops.
4.4.2 4t (Latch Trigger)
4T stands for Four Touch or ‘Latching’ mode.
This function is useful for longer welds as the trigger is not required to be held on continuously and thus
reduced operator fatigue. It also enables utilization of various advanced arc functions.
With Bi-Level Off: When the trigger button is pressed initially it will ignite the arc with an amperage
level as per I
START
Start Current setting. When the trigger is released the amperage will begin Slope-Up
(as per Slope-Up ts[sec] setting) up to Main Current (I
2
) amperage level. When trigger is pressed again
the amperage will begin Slope-Down (as per Slope-Down te[sec] setting) to Finish Current (Ie) amperage
level. When trigger is finally released again the arc will stop.
With Bi-Level On: When the trigger button is pressed initially it will ignite the arc with an amperage
level as per I
START
Start Current setting. When the trigger is released the amperage will begin Slope-Up
(as per Slope-Up ts[sec] setting) up to Main Current (I
2
) amperage level. Pressing the trigger and
releasing quickly will toggle the amperage output between Main Current (I
2
) amperage level and Base
Current (I
1
) amperage level. When trigger is pressed and held down again the amperage will begin Slope-
Down (as per Slope-Down te[sec] setting) to Finish Current (Ie) amperage level. When trigger is finally
released again the arc will stop.
4.4.1 SPOT (Spot Weld Function)
Spot Weld Time setting is adjustable from 0 – 10 seconds. This controls the length of time for the weld.
When the trigger button is pressed and held down on the TIG torch, the machine will weld for the set
time and then stop. This is great for producing very precise weld size or ensuring consistent weld
size/length when spot welding, tacking or stitch welding.
