Product description:

Electric Welding Machine adopts advanced IGBT inverter technology with inverter frequency of 33KHz, small size and light weight.

The temporary load rate is high, the overall efficiency is high, and the energy saving effect is remarkable.

It adopts leading control method and advanced control scheme to significantly improve the performance of the welder and meet the welding process requirements to a greater extent.

It can be widely used to weld various acid-base electrodes.

It has the advantages of easy-pull arc, small splash, stable arc and good shape.

Its high efficiency, energy saving, light weight, good dynamic characteristics, and thrust adjustment function can increase the depth of the weld pool.

It has a higher no-load voltage and has a thermal arc ignition function.

It is widely used and can be used for aerial work, field work, indoor and outdoor decoration, etc.

It has a preset table display function, and adopts a humanized slope new design, which is easy to operate.

Electric Welding Machine Maintenance Methods

1) check all kinds of connecting and inserting wires in the machine for bad contact

2) there is a disconnection or bad contact at the output terminal

3) inverter circuit fault (abnormal indicator) please unplug one inverter board power supply power line (near the front panel of the VH-07 plug-in) power line and transformer (near the fan VH-07 plug-in) reboot; if abnormal indicator does not light the fault in the inverter fault, or in another inverter next. Turn off the power, the power supply power line fault inverter plug (power line of the main transformer plug), then reboot:

A. if the abnormal indicator light is not on, the fault is on the middle plate;

It is possible that the middle plate transformer is damaged. The primary inductance and the Q value of the main transformer can be measured by an electric bridge, and each transformer is measured separately, if the inductance or Q value is very small, replace it

It is possible that the rectifier tube of the plate is damaged and replaced

B. if the abnormal indicator light is out of order on the MOS board, the individual inverter field effect reaction tube is broken and replaced by the same type of field effect transistor

4) feedback circuit failure (abnormal indicator light), and dealers or manufacturers contact

Great spatter in manual arc welding 

The output polarity connection is unreasonable, and the output polarity is changed
