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

fade‐out and wire-feeding speed during the [t.dn] time is tested, and then the
