- Page 1 ZX7-400/500/630HD ARC WELDING MACHINE MANUAL INSTRUCTION (PLEASE READ CAREFELLY BEFORE OPERATING)
- Page 2 Safety Depends on You Huayuan arc welding and cutting equipment is designed and built with safety in mind. However, your overall safety can be increased by proper installation ... and thoughtful operation on your part. DO NOT INSTALL, OPERATE OR REPAIR THIS EQUIPMENT WITHOUT READING THIS MANUAL AND THE SAFETY PRECAUTIONS CONTAINED THROUGHOUT.
- Page 3 C a u t i on s Arc and arc rays may harm health. Arc welding can be hazardous. All performing welding workers ought to have health qualification that provided by authority organization. Protect yourself and others from possible serious injury or death. Keep children away. Pacemaker wearers should consult with their doctor before operating.
- Page 4 ● Spatter: Welding or cutting spatter can cause fire or explosion. Remove fire hazards from the welding area.If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.
- Page 5 maintenances. When engine is hot, it is forbidden to open the airtight cover of the radiator water tank to avoid hurt by the hot vapor. ● Electromagnetic: Welding current going though any area can generate electromagnetic, as well as the welding equipment itself.

HF current through the rectify of the full bridge. While after the depression of the HF transformer, rectified by the FRD and filtered by the reactor, the HF current will change to the low-voltage but high welding current. The control circuit control the output current through the adjusting of the pulse width. The negative feedback signal, which is the real welding current get from the output current sensor, put into the special PWM circuit after compared with the current adjust signal, then output the driving pulse to control the IGBT, so that the output current will keep stable to get descending external characteristic. -
