recommendations on the welding process with semi-automatic machines. Remember,
these parameters are different for each case.

5.1 WELDING PROCESS CYCLE - MIG/MAG - 2T

To change the value of any function, see cl. 6.1.

5.1.1 BUTTON FUNCTION ON THE TORCH - 2T

It is used when welding short and medium length 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 for time [t.Pr] is activated (gas valve
opens), then the signal to turn on the source and the wire feeder motor is sent. From that
moment, the welding process starts, at the same time the function of gradual entering the
welding mode for the time [t.uP], as well as additional functions can be executed (for
example, pulse mode, which we will consider in detail in the following paragraphs). All this
is done according to the welding process cycle given in the cyclogram of paragraph 5.1.
After releasing the button, the function of gradual decay of current and wire feed speed for
time [t.dn] is executed, then the source is turned off. Then the post-purging function of the
welding zone with gas is executed for the time [t.Po] (the gas valve is closed with a delay).
