T1: The main button is pressed, the cycle starts at PreGas and stops
in the I_Start phase.
T2: The main button is released, the cycle continues in UpSlope and
in welding.
LOG : this mode is used during welding :
- A brief press of the main button (<0.5s), the current switches
from I welding current to I cold and vice versa.
- The secondary button is kept pressed, the current switches from I
welding to I cold.
- The secondary button is released, the current switches from I cold
to I welding.
T3: A long press on the main button (>0.5 sec.), the cycle switches
to DownSlope and stops in the I_Stop phase.
T4: The main button is released, the cycle ends with PostGas.
For this mode it may be convenient to use the dual button torch option or dual button with potentiometer. The "up" command keeps the same function
as the single button or trigger torch. The secondary button can, when pressed, switch to the cold current. The welding torch potentiometer, when
present, allows the welding current to be adjusted from 50 % to 100 % of the setpoint.
