It is used when welding long welds. The function is as follows: when you press the
button on the torch, the control signal goes to the control unit, the function of pre-
purging the welding zone with gas (gas valve opens) is executed; after the first
release of the button, the signal to turn on the source and the wire feeder motor is
released. From that moment, the welding process starts. At the same time, the
function of gradual entering the welding mode in time [t.uP], as well as additional
functions (for example, the last generation of PATON digital sources have a pulse
mode) are executed. All this is according to the welding process cycle shown in the
cyclogram of cl. 3.2.
