Capacitive Energy Storage Point (Convex) Welding Machine
DKR-6000 DKR-15000 DKR-30000
Energy saving, power saving, high efficiency, low operating cost, and high welding quality.
Product Overview: Capacitive energy storage point (convex) welding machine uses capacitors to store energy, achieving charging and discharging first. Compared with traditional power frequency and medium frequency point (convex) welding machines, it has lower instantaneous power, faster charging, shorter welding time, and larger output current when used from the power grid, achieving stronger welding and better surface quality. For example, the surface oxidation and deformation of welding points are small, and there is no blackening or discoloration after welding, eliminating the need for subsequent polishing processes, saving labor, energy, and consumption.

1,How do we install the machine?
Answer: For some simple machines, we will provide you with English operation manuals, operation videos, and online guidance and training for your engineers to easily set up the machine. For more complex machines, we will send engineers to your country to assist with installation and training. However, there will be additional costs for engineers, including wages, visa fees, round-trip airfare, and accommodation, which will be borne by the buyer.
2,How to reduce energy consumption during the welding process of the spot welding machine?
Answer: To reduce the energy consumption of the spot welding machine, several aspects can be considered. Firstly, select efficient and energy-saving welding equipment and power supply systems to ensure the equipment operates in the optimal working state. Secondly, optimize welding parameters to avoid excessive current and voltage, reducing unnecessary energy consumption. Additionally, schedule production plans reasonably to avoid prolonged idling of the equipment, reducing standby energy consumption. Meanwhile, strengthen equipment maintenance and upkeep to ensure normal operation and efficient utilization of the equipment.
3,Can the spot welding machine be customized to meet special requirements?
Answer: Yes, we pay close attention to customers' personalized needs. If you have special welding requirements or process requirements, we can customize development according to your needs to tailor a spot welding machine that meets your requirements, such as custom fixtures, electrode heads and arms, and increased height or length of the machine body.
4,Does the spot welding machine support multi-stage welding functions?
Answer: Yes, our spot welding machine supports multi-stage welding functions. Users can set multiple welding stages according to actual needs, and each welding stage's parameters can be independently adjusted to meet the requirements of complex welding processes.
5,How is the welding pressure of the spot welding machine adjusted? What are the influencing factors?
Answer: The welding pressure of the spot welding machine can be adjusted through the pneumatic system or mechanical devices. The main factors affecting welding pressure include material thickness, hardness, and welding process requirements. Proper welding pressure ensures the firmness and quality stability of the welding joint.
6,How to select suitable electrode materials for the spot welding machine?
Answer: Selecting suitable electrode materials is crucial for welding quality and stability of the spot welding machine. Common electrode materials include copper, copper alloys, tungsten, etc. When choosing electrode materials, factors such as the type, thickness, and properties of the welding material, as well as temperature, pressure, and current during the welding process should be considered. Typically, copper or copper alloys can be chosen as electrode materials for welding materials with low melting points, while tungsten or other materials resistant to high temperatures may be required for welding materials with high melting points or special properties.
7,Do spot welding machines have safety protection measures?
Answer: Yes, our spot welding machines have comprehensive safety protection measures. The equipment incorporates various safety mechanisms such as overload protection and overheat protection, ensuring that power can be cut off promptly in case of abnormal situations to protect the safety of operators and equipment.
