What is the cause of burning resistance in the drive board of zx7-400 inverter DC welder? Please look at the drive board.

The electric burning resistance of the driving board of zx7-400 inverter DC welding machine is usually the result of many factors. The first thing to consider is the quality of the resistor itself. In the manufacturing process of resistors, if there are problems such as material defects, improper technology or unreasonable parameter design, it may not be able to withstand the normal working current during use, and then burn out.

In addition, the circuit design on the driver board is also a major factor. If the circuit design is unreasonable, such as improper resistor selection, power capacity mismatch or insufficient heat dissipation design, it may lead to overheating of the resistor in the working process and eventually lead to burning.

At the same time, the working environment and use conditions can not be ignored. Using electric welding machine in high temperature, humid or dusty environment will lead to the decline of resistance and increase the risk of burns. In addition, if the welding machine is subjected to frequent voltage fluctuations or overload shocks during use, it will also cause resistance damage.

To sum up, there may be many reasons for burning resistance in the driving board of zx7-400 inverter DC welding machine, including the quality problem of the resistance itself, unreasonable circuit design and the influence of working environment and using conditions. In order to solve this problem, we can ensure the stable operation and prolong the service life of the welding machine by improving the resistance quality, optimizing the circuit design and improving the working environment and using conditions.
