ZX7-400 (z115)
1, using the MOSFET field effect tube inverter technology, the inverter frequency can reach 100KHz above
2, the technology is mature, the performance is stable, the whole machine conversion efficiency is high.
3, high efficiency, energy saving, and has good dynamic characteristics, high no-load voltage easy to arc, and better thrust compensation, arc stability, soluble pool easy control.
4, the characteristics of the welding machine for the constant flow characteristics of external arc thrust control. In the normal arc voltage under constant current characteristic, the welding current does not vary with the variation of arc length to ensure stable welding, arc elastic; when the arc length is too short arc voltage is too low, the current can be reduced with the increase of arc voltage and arc length, in order to make automatic recovery (called arc thrust). The arc stability, thrust can be adjusted independently; when the arc voltage can be maintained to arc, the external characteristics of characteristics to steep, so as to avoid short circuit caused by excessive current and spatter.
5, with the preset table display function, can be connected to remote control box control, can be widely used in the field of long-term operation, indoor and outdoor decoration, easy to install, easy to operate and so on.
