FAQ

1,How is the welding accuracy of spot welding machines ensured?
Answer: Our spot welding machines adopt advanced control systems and precise welding parameter adjustment functions to ensure the stability and accuracy of the welding process. Through precise control of current and time, high-quality welded joints can be achieved to meet your requirements for welding accuracy.

2,Can the spot welding machine work continuously for a long time?

Answer: The spot welding machine is designed to accommodate continuous operation, but prolonged continuous operation may affect the equipment's stability and lifespan. To ensure the equipment's normal operation and extend its lifespan, the water circulation cooling system should operate normally during use to avoid overheating or overloading the equipment.

3,What should be considered during the transportation and storage of the spot welding machine?

Answer: When transporting and storing the spot welding machine, ensure that the equipment is turned off and the power is disconnected. Also, avoid impacts and vibrations to prevent damage to internal components. The storage environment should be kept dry, ventilated, and protected from direct sunlight and high temperatures.

4,How to avoid overheating during the use of the spot welding machine?

Answer: Overheating is a common problem during the use of the spot welding machine, which may cause equipment damage or affect welding quality. To avoid overheating, the following measures can be taken: Firstly, ensure there is good ventilation around the equipment for heat dissipation. Secondly, regularly check the working status of the cooling system to ensure that the cooling water or cooling fans operate normally. Additionally, schedule work time reasonably to avoid prolonged continuous operation of the equipment causing overheating. Finally, for work under high load or high-temperature environments, consider using higher-spec cooling systems or other cooling measures.

5,What is the lifespan of the spot welding machine? What regular maintenance is required?

Answer: The lifespan of the spot welding machine varies depending on usage environment and maintenance. To extend the equipment's lifespan, we recommend regular cleaning, tightening loose components, and inspecting electrical connections. Additionally, we provide regular inspection and maintenance services to ensure the long-term stable operation of the equipment.

These additional questions and answers further cover aspects such as welding modes, remote control, factors affecting welding quality, automatic detection capabilities, electrode adjustments, equipment lifespan, and maintenance. We hope they meet your requirements for online inquiries. Of course, specific answers may need to be personalized based on the actual requirements of customers and the characteristics of your company's products.

6,What are the special requirements when welding stainless steel with the spot welding machine?

Answer: When welding stainless steel with the spot welding machine, special attention should be paid due to the high thermal conductivity and low resistivity of stainless steel. Several points to note include: Firstly, select appropriate welding parameters, such as appropriately increasing welding current and welding pressure, to ensure fusion penetration and firmness of the welding joint. Secondly, choose electrode materials and shapes suitable for stainless steel welding to improve the stability and welding quality of the welding process. Additionally, stainless steel is prone to oxidation and discoloration during welding, so proper protective measures, such as using shielding gas or flux, should be taken to prevent oxidation and discoloration.

7,Does the spot welding machine have an energy-saving mode or sleep function?

Answer: Yes, some advanced models of spot welding machines are equipped with energy-saving mode or sleep function. When the equipment is idle or not in use for a long time, the energy-saving mode can automatically reduce the power consumption of the equipment to achieve energy saving. The sleep function can automatically enter a low-power state after a period of idle time, further reducing energy consumption. These functions help reduce energy waste and operating costs.


8,Can we send samples to you for welding tests?
Answer: Yes. You can send samples for welding tests to us, and after testing, we will send you pictures and videos. If necessary, we can also return the samples to your country so that you can inspect the welding quality before ordering the machine.
