GZ-600 argon arc welding machine circuit-03

G2r600 argon arc welding machine is an AC arc welding machine that uses argon as a shielding gas
. The circuit is shown in the figure. The input power of welding transformer Ti is
103kV. A. The no-load voltage is 220V, the working voltage is 20V, and the welding current
adjustment range is 50-600A. The diameter of tungsten electrode is 1-6mm. The control circuit
can ensure that the electrode automatically delivers argon within 1 to 2 seconds before arc ignition, and
automatically stops argon within 8 to 15 seconds after the arc is extinguished. A high-frequency oscillator is used for arc ignition. After arc ignition, the welding transformer is automatically connected and the welding current is automatically cut
off. When no-load, the welding power supply is automatically cut off and the argon supply is stopped. The welding current
is achieved by adjusting the iron core of the reactor L by the forward and reverse rotation of the servo motor Mi.
