5.1.1 WELDING CYCLE – MIG/MAG-2T
See Clause 6.1 for sequence of changing the value of any function in the
current welding mode.
5.1.2 FUNCTION OF BUTTON ON A 2T TORCH
It is used in welding of short and medium length welds. The function is as
follows: when pressing the button on the torch, the control signal enters the
control unit, the function of pre-purging the welding zone with gas during the time
[t.Pr] (the gas valve is opened) is processed, then a signal is given to turn on the
source and the wire feed motor. From now on, the welding process begins; at the
same time, the function of smoothly entering the welding mode during the [t.uP]
time is worked out, as well as additional functions can be worked out (for example,
a pulsed mode, which we will discuss in detail in the following clauses) given on the
cyclogram in Clause 5.1. After the button is released, the function of arc current
fade‐out and wire-feeding speed during the [t.dn] time is tested, and then the
source turns off. Next, the function of the post‐purging of the welding zone with
shielding gas during the [t.Po] time is worked out (the gas valve is closed with a
delay).
