- Reduce operating cost
The energy storage welder adopts the transistor element to carry on the program control. The heavy AC contactor and ignition tube are replaced by SCR in charge-discharge switch. As a non-contact high current switch, SCR has the characteristics of small size, no noise, easy to use and so on. In particular, its pressure drop is only 1/10 of the ignition tube, so that electricity can be used effectively. The charging voltage is precisely controlled and continuously adjustable by electronic switches and monitored by voltmeters. The circuit is equipped with an overvoltage protection device to prevent the breakdown of the energy storage capacitor.
With the development of energy storage electrolytic capacitor, the energy storage capacity of energy storage welder can be very large, but the volume is very small.
Energy storage welding machine can reduce electrode heat and mechanical pressure loss. No current peak, no interactive magnetic field, electrode life can be increased by 30 -50%. Compared with ordinary resistance welding machine, energy storage welding machine has higher equipment efficiency, more efficient welding transformer, no secondary circuit reactance loss, the ability of saving 20-40% of electricity.
The welding process of the energy storage welding machine is controlled by PLC automatic programming. There is no requirement for the welding skill of the operator. The operation is simple and easy to master. Equipment Maintenance and repair is very simple.
- Reduce the investment cost
The energy storage welding machine has low requirement to the power grid and does not affect the power grid.
The principle of energy storage welding machine is to charge the capacitor through a small power transformer and then discharge the workpiece through a large power resistance welding transformer. The charging current of the capacitor energy storage welding machine is far less than the discharge current, so it is not easily affected by the fluctuation of the electric network. Due to the small charging power, the impact on the power grid is much smaller than that of AC spot welders and secondary rectifier spot welders with the same welding capacity.
As the primary current is small, the use of smaller primary cables reduces power supply demand, that is, reduce the electrical investment in infrastructure. The three-phase balance input of power supply does not pollute the power network and does not need compensation and filtering equipment. The weight and size of the welding transformer can be greatly reduced.
- Stable welding quality reduces quality cost
The welding parameters of energy storage welding machine can be adjusted accurately and dynamically. The self-adaptive adjustment can obtain better welding joint quality. No material overheating, less spatter, no need to clean after welding.
Solder joint surface oxidation and deformation is just little. Solder joint no blackening it saves the grinding process.
Because its discharge time is very short, only ten milliseconds, it ensures the stability of welder performance and welding quality consistency even in the case of power supply voltage fluctuations.
Long-term welding work will not lead to equipment overheating, and will not affect the welding capacity and welding performance.
- Wide range of weldable metallic materials
The discharge range of the energy storage welding machine does not have the cooling interval when the current is reversed in the AC circuit, so it is more suitable for welding light metals with good electrical and thermal conductivity, such as aluminum, copper, silver and nickel, alloy material, low carbon steel, stainless steel, nickel-chromium wire, high strength steel, galvanized steel, etc.
