Product Details

Product description:

1, the use of advanced IGBT inverter technology, inverter frequency 33KHz, small size, light weight

2, the temporary load rate is high, the efficiency of the whole machine is high, and the energy saving effect is remarkable

3, the leading control mode, advanced control program, significantly enhance the performance of welding machine, to a greater extent to meet the welding process requirements

4, it can be widely used in welding various kinds of acid and alkaline welding rod

5, it has the advantages of easy arc drawing, small splash, stable arc and good shaping

6, high efficiency, energy saving, light weight, and good dynamic characteristics, with thrust adjustment, can increase the depth of the molten pool

7, higher no-load voltage, with hot arc ignition function, easy to arc

8, widely used, can be used for aerial work, field operations, indoor and outdoor decoration, etc.

9, with preset table display function, adopt humanized slope new appearance design, 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
