 HWASHI MCB Spot Welding Machine

 

• Medium Frequency Inverter  Spot Welder

• The current is rectified in order to supply DC welding current.

• Helps to reduce the energy of iron core material.

• The frequency of welding transformer is promoted from 50/60Hz of mains supply to 1000Hz.

• Transform the electric energy into DC power

• Energy Saving: Compare with using ac power, it can help to reduce the consumption of electricity. The transformer of the same weight could output more energy. It can also be conveniently used with the large automatic welding clamp.

• In a semi-automatic plant, one medium frequency transformer can replace many low frequency transformers so as to reduce the parallel connection situation in secondary circuit.

• Improve the power factor, reduce the production cost.

• Reduce interference in secondary circuit which is in the large open area

• To make the power supply unit load balance: MF inverter spot/projection welder adopts the three-phase sources which can store energy.

• More adaptable to the fluctuation of power grid and voltage drop.

• More precise and fast control of current

• More reliable process: For most of the applied resistance welding metals, to use DC to weld will help to achieve a better effect.

• The technology of MF system is more traditional and reliable which can prevent the damage results from the breakdown of silicon controlled.

• Reduce operation cost, including saving the energy of each spot welding and reducing the cycle of welding.
