    EPS GENERA 161 welding machine no output voltage, no 24 V reading on the relay's

    On the AC rectifier card of the EPS GENERA 161 small welding machine, the tank capacitors on the AC rectifier unit are filled to the required value, but the outputs of the welding machine are 0 Volt, 24 V does not fall on the relay, that is, on the coil legs of the relay has voltage of 24 V, and...

    KL MMA160 inverter igbt arc welding machine does not weld although it gives an appropriate value of 52 output voltage

    The output of the KL MMA 160 inverter igbt arc welding machine is 52 Volts and as it should be. The fan is also working. 4 High-Speed Switching Diodes (1N 4148 5T) diodes exploded on the Transformer Rectifier circuit card of the machine, I replaced them with new ones, but it still does not...

    "If all the IGBTs are good, then all the SMD resistors, capacitors and zeners on the legs of the IGBTs are good"

    Is there such a thing as "If all the IGBTs are good, then all the SMD resistors, capacitors and zeners on the legs of the IGBTs are good" in the inverter welding machines? That is, as long as at least one of the IGBTs does not explode, will the SMD elements underneath remain intact?

    The outputs of the FIMER 201 welding machine give 0 Volts and a clicking sound is heard from the control circuit

    The outputs of the FIMER 201 welding machine give 0 Volts and a clicking sound is heard from the control circuit and the yellow and green light lamps are constantly flashing. The Output Voltage is fluctiating. Why is the machine giving this error? What should be done to fix this fault? Which...
