Welding machine use and troubleshooting

Inverter DC manual arc welding machine and inverter semi-automatic gas shielded welding machine are mainly used for welding various metals such as low carbon steel, medium carbon steel and alloy steel. Inverter argon arc welding machine is mainly used for welding stainless steel, aluminum, titanium, zirconium, etc.​igbt inverter welder, especially stainless steel sheet welding.


Troubleshooting: Boot Protection

The reasons for the failure are as follows:

1. The field tube is damaged, it is overcurrent protection.

2. The secondary rectifier tube is damaged, which is overcurrent protection.

3. If the intermediate frequency transformer is damaged, it is overcurrent protection.

4. The temperature control switch is damaged, which is error protection.

5. The protection circuit of the control board is damaged, which is an error protection.


When the protection circuit of the welding machine does not work, the overcurrent of the welding machine will cause the machine to explode. During maintenance, special attention must be paid to whether the protection circuit is normal.
