START
START = 0 : the welding cycle is started with the JOB selected. Changing the JOB will have no effect during welding. When ARC ON = 0 is received,
the welding arc is lit. START = 1: the welding cycle ends (DownSlope ... PostGas). When ARC ON = 1 is received, the welding arc is switched off.
If the default context is selected (JOB0), the HMI parameters can be accessed without welding.
Regardless of the JOB or context selected, the current is always adjustable via the potentiometer (REG I).

R2 : 3.3 kΩ
R3 : 6.8 kΩ

R4 : 15 kΩ
R5 : 33 kΩ
R6 : 100 kΩ
In position 1/2/3/4/5 :
REG I = 5V = 0% variation,
REG I = 0V -> -15% variation
REG I = 10V -> +15% variation
If POSITION 0, then the variation occurs over the entire
current range permitted by the product.
