For double button or double trigger + potentiometer torches, the «high» trigger has the same function as the single trigger torch. The «low» trigger,
when held down, switches to the cold current. When using a potentiometer torch, the welding current can be adjusted between 50% and 100% of the
38
value displayed. The Up & Down function allows the current at the torch to be set very precisely (the complete current range is adjustable).

T1 - The main button is pressed, the welding cycle starts (Pre-Gas,
I_Start, upslope and welding).
T2 - The main button is released, the welding cycle is stopped
(downslope, I_Stop, Post-Gas).
For two-button torches in T2 only, the secondary button is treated as
the main button.
T1 - The main button is pressed, the cycle starts from Pre-Gas and
stops at the I_Start phase.
T2 - The main button is released, the cycle continues to upslope
and welding.
T3 - The main button is pressed, the cycle goes to downslope and
stops in the I_Stop phase.
T4 - The main button is released, the cycle ends with the Post-Gas.
NB: for double button and double button + potentiometer torches
T4 => «up/weld current» button turns on the potentiometer, the «down»
button turns it off.
T4
T1 - The main button is pressed, the cycle starts from Pre-Gas and
stops at the I_Start phase.
T2 - The main button is released, the cycle continues to upslope
and welding.
LOG: This function is used during welding:
- a quick press of the main button (<0.5 s) switches the current from
I-welding to I-cold and vice versa.
- if the secondary button is pressed, the current switches from
I-welding to I-cold.
- if the secondary button is left unpressed, the current switches from
I-cold to I-welding.
T4
T3 - After holding down the main button (>0.5 s), the cycle begins to
downslope and stops at the I_Stop phase.
T4 - The main button is released and the cycle ends with Post-Gas.
