FIELD: process engineering.
SUBSTANCE: invention relates to making welding electrode tip 13 wit relevant combination between material-diameter for fitting in guide channel 12. Welding electrode 13 is fed wire feeder via, at least, one guide channel 12 by means of contact tube arranged in welding torch 10. For process automation purposes, electric arc 15 is generated, prior to dressing, between contact plate 30 connected with electric power supply and welding electrode 13 to make electrode tip with due allowance for electrode material and diameter. Welding electrode tip is made half-round with diameter not exceeding, in fact, that of welding electrode 13.
EFFECT: easier electrode dressing.
