Do you feel helpless in the face of the problem of medium frequency spot welding machine overheating? Indeed, overheating of the machine not only affects the welding quality, but also may bring serious safety hazards. Today, let us explore the root cause of the medium frequency spot welding machine overheating and find a solution.
The six main culprits of medium frequency spot welding machine overheating are revealed:
Abnormal circulation cooling system: First, make sure that the circulating cold water system is operating normally, the chiller is turned on, and check whether the water channel is unobstructed to avoid blockage and poor heat dissipation.
Insulation resistance problem: Check whether the insulation resistance between the electrode holder and the machine body meets the standard to prevent local short circuit caused by poor insulation, which is often a small but critical negligence that causes voltage overheating.
Improper water flow parameters: Adjust the water inlet pressure, water flow and water supply temperature to the appropriate range to ensure the best cooling effect.
Contact surface oxidation: Carefully check the contact surface of the copper soft link, electrode arm, electrode rod and electrode head to see if there is serious oxidation, which will increase the contact resistance and thus aggravate the heating.
Electrode head wear: Evaluate whether the cross section of the electrode head is severely worn due to long-term use. Excessive wear will cause the welder to overload and cause overheating.
Load duration rate exceeds the standard: According to the thickness and specifications of the welded product, reasonably set the current of the medium frequency spot welder, and monitor whether the load duration rate is kept within the safe range.
