AC resistance welding machine
Products Description
The machine is an AC resistance welding machine, which is controlled by a microcomputer. It can set the optimal welding current that can ideally prevent spatter and suppress overheating of the welding current through the processing effect of the slow-rising current in the front section and the heating processing effect of the current in the back section.
Main Features
1. Microcomputer Controlled: Equipped with an advanced microcomputer control system for precision and stability in the welding process.
2. Efficient Welding: Utilizes resistance heat and the plastic deformation energy of the welding area to form a metal bond close to the lattice distance between two metal atoms, producing a sufficient number of common grains for a strong weld.
3. Adjustable Settings: The current size and welding time are adjustable for versatile operation and ease of use.

Precautions
1. Install the terminal cover: Direct contact with the terminal block can cause electric shock. Always install the terminal cover during use.
2. Securely connect wires and cables: Improper connection methods can cause fire and electric shock.
3. When handling the connector terminals of the connecting cables, use appropriate tools (wire strippers and crimping tools) and be careful not to damage the copper wires inside, as this can cause fire and electric shock.
4. Install the unit in a level, non-sloping location: The unit can fall or tip over, potentially damaging it.
5. Do not place containers filled with water on top of the unit. Spilled water can damage the insulation, causing electrical leakage and fire.
6. Do not place flammable materials on top of the unit. Welding spatter can cause fires if it is spilled onto flammable materials. If flammable materials cannot be removed, cover them with a non-combustible cover.
7. Do not cover the unit with blankets or cloths during use, as this may cause overheating and fire.
8. Do not use the welding machine for any purpose other than welding. Using it in locations other than those specified can cause electric shock or fire.
9. Use soundproofing tools. The noise generated by the device during operation can damage your hearing.
10. Please use a fire extinguisher. Please place a fire extinguisher in the area where the device is installed as a precaution.
11. Perform regular maintenance and inspections: Perform regular maintenance and inspections, and repair any damaged parts before using the device.
Q&A
1. Can one mold be used for different sizes of heating plates?
Yes, the lower electrode of the welding machine remains fixed, and the upper electrode is adjustable to accommodate different sizes of heating plates. Once adjusted, the upper electrode can be locked in place with screws.
2. What is the production capacity per hour and per day?
The Automatic Spot Welding Machine can produce up to 2,880 pieces in 8 hours.
3. Can the Automatic Spot Welding Machine be operated continuously for 24 hours?
Yes, the Automatic Spot Welding Machine is capable of continuous operation for 24 hours.
4. What are the machine's consumable parts?
The upper and lower electrodes need to be regularly maintained by grinding away carbon deposits using a grinder. You should also grind a groove into the electrodes and adjust the electrode screws accordingly.
