How to deal with different faults of high frequency quenching machine?
1. There are pores in the workpiece during the welding process of the high-frequency quenching machine, which generally has nothing to do with the welding equipment itself: it may be the damage or blockage of the gas regulator flowmeter, the failure of the welding gun, the surface of the base metal is not clean, and the connection points are loose. .
2. The unstable welding arc voltage has nothing to do with the equipment: the welding output part of the high-frequency quenching machine is loose or the contact with the welding torch is loose. The contact tip of the welding torch has poor contact with the conductive rod or is seriously worn. The connection between the power cord and the distribution box is loose.
3.No ignition: Make sure that the voltage of the main engine is not lower than 60V, check whether there is a problem with the welding gun, and see whether the welding gun hooks the switch and the wire feeds fast but does not start arcing. At this time, stop immediately to see if the welding gun of the high-frequency quenching machine is not. Leakage, see if the contact point of the welding cable is loose or carbonized or damaged.
