This design of Dual Head Welder is actually the Capacity Discharge welding Machine. 

Capacity Discharge welding is to store the electric charge in a certain capacity capacitor, so that the welding torch can pass through the welding material and the workpiece instantly with high frequency pulse discharge at 2-3 times per second, so that the welding material and the workpiece can reach the metallurgical contact point at an instant. 

  The welding machine is composed of a mechanical part and an electrical part, and the circuit control is the core part of the resistance welding technology.The single-chip computer control technology is widely applied in the welding field and has become the mainstream of the development of the control system of the solder mask.The machine uses a professional industrial control single-chip microcomputer as the control core, and adopts a variety of software and hardware anti-interference measures for the capacitor energy storage welding machine control system.

  Compared with other welding methods such as AC welders, the instantaneous power drawn from the power grid is low, the load of each phase is balanced, the power factor is high, and it can provide concentrated energy to the welding zone. It can obtain workpieces with good surface quality and small deformation, which can be welded. Some hard-to-weld non-ferrous metals with good thermal and electrical conductivity.It is suitable for welding aluminum, copper silver, nickel metal and alloy materials.This welding method has been widely applied in industrial production, such as hardware, household appliances, electronics, metal utensils and other industries.

1. The controller adopts a single-chip microcomputer control system, which is easy to operate and maintain, and the control specification is accurate and stable;

2. Combination of software and hardware, synchronous control, guarantee welding quality and high precision;

3. The capacitor voltage can be adjusted arbitrarily with 1V accuracy from 35~400V;

4. The circuit charges and discharges quickly, the welding current is stable, and the charge and discharge frequency is high;

5. Digital display panel, simple operation and beautiful appearance;

6. There is a button sound to remind the operator that the operation is successful and prevent wrong operation.
