Agera's Capacitor Discharge(CD) Welding Machine
Agera is a professional manufacturer of capacitor discharge(CD) welding machines, offering a range of models in stock. Unlike other resistance welding machines, capacitor discharge welders use high current, high pressure, and short welding times, making them ideal for projection welding in the automotive industry, including hot-stamped steel, high-strength steel, and nuts and bolts. They’re also suitable for multipoint projection welding and ring projection welding on various metal materials. Our capacitor discharge welders have a maximum energy storage of 200KJ, enabling them to weld large metal parts.
Capacitor Discharge Projection Welder
Small models of welding machines are generally used for silver spot, copper projection welding, and some fine electronic parts welding.
It can be used for projection welding of about 1 mm metal parts, and can output a maximum short-circuit current of 28KA.
Generally used for welding small metal fasteners, stamping parts and wire multi-point projection welding ring projection welding process
It is often used for multi-point projection welding of metal parts in auto parts industry and home appliance industry.

For special materials such as hot formed steel, high carbon steel and other parts of the projection welding process
It is used for the ring convex welding process with high sealing requirements, and there is no damage to the appearance after welding.
It can release 180KA welding current instantly, and can weld large ring nuts.
Advantages Of Agera's CD Spot Welder

Agera capacitor discharge spot welding machine has inverter control and secondary constant current, so the current is more stable and controllable; this feature has a great impact on the welding effect, which is not only beneficial to the stability of the welding, but also enhances the durability of the machine, while also affecting the power grid. The impact is relatively small, extending the life of the machine.

Capacitive discharge welding is the fastest form of resistance welding, and its welding speed can reach 2 milliseconds once. The reason is that its welding current is stored in advance through multiple sets of capacitors, when the welding switch is pressed, the capacitor will instantly release the stored energy, and the welding is completed quickly.

The capacity discharge welding machine of Agera has great advantages in welding nuts, bolts, fasteners and stamping parts. Due to the fast welding speed, the workpiece is not easy to deform, the welding is seamless, and the products after welding do not need secondary processing. In addition, the energy storage welding machine each discharge consistent, to ensure the stability of welding quality.
