How to solve the medium frequency inverter spot welding machine welding overheating?

medium frequency inverter spot welding machine in the process of use, sometimes there will be overheating phenomenon, which is also one of the common equipment failure of medium frequency inverter spot welding machine welding equipment, the following small series for you to introduce how to solve this overheating phenomenon.

1, check whether the insulation resistance between the electrode seat of the intermediate frequency inverter spot welding machine and the body of the spot welding machine is normal and short-circuited;

2, check whether the water inlet pressure, water flow and water supply temperature of the cooling system are appropriate, and check whether the waterway cooling system is blocked by dirt;

3, check whether the copper soft joint and electrode arm, electrode rod and electrode head are seriously oxidized;

4. Check whether the cross section of the electrode head can be added too much due to wear, whether the welding thickness and load connection rate can be overrun, etc., thus causing the welding machine to overload and generate heat.
