The intermediate frequency spot welding machine must be properly grounded before use to ensure personal safety. Before using the intermediate frequency spot welding machine, a 500V megohmmeter should be used to test the insulation resistance between the high voltage side of the welding machine and the casing, which should not be less than 2.5 megohms before it can be powered on. When repairing, the power supply must be blocked first before opening the box for inspection. The welding machine should be watered before welding, and operation is prohibited without water. The cooling water should ensure the supply of industrial water at 5-30 ℃ under an inlet pressure of 0.15-0.2MPa. After completing the operation of the mid frequency spot welding machine in winter, use compressed air to blow out the water in the pipeline to avoid freezing and cracking the water pipe.
The lead wire of the intermediate frequency spot welding machine should not be too thin or too long. The voltage drop during welding should not exceed 5% of the initial voltage, and the initial voltage should not exceed ± 10% of the power supply voltage. When operating a spot welding machine, gloves, aprons, and protective goggles should be worn to avoid sparks flying out and causing burns. Sliding should adhere to excellent lubrication, and metal splashes should be removed after use. After 24 hours of use of the new welding machine, the screws of each component should be tightened once, especially paying attention to the connection screws between the copper flexible joint and the electrode. After use, the oxide between the electrode rod and the electrode arm should be removed frequently to ensure excellent touch.
When using a medium frequency spot welding machine, if it is found that the communication touch device is not firmly engaged, it indicates that the power grid voltage is too low. Users should first deal with the power supply issue, and can only use it after the power supply is normal. The requirement is that if there are quality issues with the main components of the newly purchased welding machine within half a month, a new welding machine or main components can be replaced. The welding machine host comes with a one-year warranty and provides long-term maintenance services. Normally, after notifying the manufacturer, the service will be provided within three to seven days based on the distance of the journey. Welding machine damage caused by user reasons is not covered by the warranty. Vulnerable and consumable parts are not covered by the warranty.
The contact area of the electrode determines the current density of the intermediate frequency spot welding machine, and the electrical resistivity and thermal conductivity of the electrode material are related to the generation and dissipation of heat. Therefore, the shape and material of the electrode have a significant impact on the formation of the weld core. With the deformation and wear of the electrode tip, the touch area increases and the strength of the solder joint decreases. The oxides, dust, oil, and other impurities on the surface of the workpiece increase the touch resistance. An excessively thick oxide layer can even prevent current from passing through. The conduction of the intermediate frequency spot welding machine may cause splashing and surface burning due to excessive current density. The presence of oxide layer can also affect the uneven heating of various solder joints, leading to fluctuations in welding quality. Therefore, completely organizing the appearance of the workpiece is a necessary condition to ensure excellent joints.
