Because hydrogen cold arc has a strong effect, so that the arc through difficult welding power supply should be higher than 300V lead the arc voltage. GH-75-type hydrogen atom welder secondary no-load voltage of 300V, working as voltage is 100V, rated welding current 75A, welding current adjustment range 20 ~ 100A, rated output capacity of 22. 5kV. A, rated duty cycle of 65%, 75% efficiency, power factor 0.36, tungsten electrode diameter 1. 5 ~ 3mm. GH-75 type hydrogen atom welder circuit shown in FIG. FIG, the electromagnetic valve Y is turned on and off to control the hydrogen used; intermediate relay KAz continue to control the welding circuit; L reactor is used to adjust the welding current; foot switch is used to disconnect SB2 welding power supply.
