What are the reasons for overheating when using a medium frequency spot welding machine

When we use an intermediate frequency spot welding machine, if we find that the machine is hot, will we be at a loss? The machine not only cannot weld the product well, but also has a great safety hazard. Let's introduce where the problem lies.

1. Check if the circulating cold water system is functioning properly, if the chiller is turned on, and if there are any blockages in the water circuit.

2. Check if the insulation resistance between the electrode holder and the body is poor, causing a local short circuit. Negligence in this small issue may lead to voltage overheating.

3. Check if the inlet pressure, water flow rate, and water supply temperature are appropriate.

4. Check if the contact surface between the copper flexible joint and electrode arm, electrode rod, and electrode tip is severely oxidized, causing an increase in contact resistance and severe heating.

5. Check if the cross-section of the electrode head has increased too much due to wear, causing the welding machine to overload and generate heat.

6. Determine the thickness and specifications of the welded product, as well as the current used in the medium frequency spot welding machine, to see if the load duration exceeds the standard.

Based on the above six points, we can find the real culprit behind the overheating of the intermediate frequency spot welding machine, prescribe the right medicine, and the problem will naturally be solved.
