For double-button torches or double-trigger torches with with a potentiometer, the 'upper' trigger does the same thing as the single trigger. The 'lower'
trigger allows the user to switch over to the cold current when it is held down. The torch's potentiometer, when activated, allows the welding current to
be adjusted from 50% to 100% of the displayed value.

T1 - The main button is pressed, the welding cycle starts (Pre-Gas,
I_Start and UpSlope, as well as the general welding mode).
T2 - The main button is released, the welding cycle is stopped
(DownSlope, I_Stop and Post-Gas).
For the double-button torch in 2T mode, the secondary button works in
the same way as the main button.
T1 - The main button is pressed, the cycle starts from the Pre-Gas
stage and stops in the I_Start phase.
T2 - The main button is released, the cycle continues into UpSlope and
then into the welding phase.
T3 - The main button is pressed, the cycle switches to DownSlope and
stops in the I_Stop phase.
T4 - The main button is released, the cycle ends with Post-Gas.
For the double-button torch, the secondary button is inactive.
T1 - The main button is pressed, the cycle starts from the Pre-Gas
stage and stops in the I_Start phase.
T2 - The main button is released, the cycle continues into UpSlope and
then into the welding phase.
LOG, this operating mode is used during the welding phase:
- by briefly pressing the main button (< 0.5 s), it switches the current
from I_Welding to I_Cold and vice versa.
- when the secondary button is held down, the current switches from
I_Welding to I_Cold.

- if the secondary button is not pressed, the current will switch from
T4
I_Cold to I_Welding.
T3 - Holding down the main button (> 0.5 s) will progress the cycle to
DownSlope and then stop the cycle in the I_Stop phase.
T4 - When the main button is released, the cycle ends with Post-Gas.
