Product Description

HWASHI Pneumatic Long Arm DC Projection Spot Welding Machines




MF DC Inverter Spot Welder is a set of advanced welding equipment. The welding transformer is in small size but the outout energy is large. Three-phase AC will be converted into DC after being rectified. Then the DC will be converted into medium frequency 1000HZ square wave to be connected to primary welding transformer  through the inverter circuit which is composed of IGBT. The MF square wave will become small  pulse DC to the electrode for welding work piece through the depressurization and recitifying process in the welding transformer. The Inverter will adjust the duty ratio of IGBT through the feedback of secondary current so as to achieve constant current of the welding process.

Widely applied to welding battery ,lighting electric resource automobile.medical apparatus and instruments,photoelectric communication, micro motor as well as requested chip inductor with high temperature enamed round wire/extra fine wire minimum size can be 0.02mm), wire rope,metal wire,nickle cup, can cutting wire and welding ,CCFL filed ,fuse,lamp filament.





1. The current in secondary weldin gloop is DC. Dramatically reduce the impact to the welding current due to the inductive reactance in secondary lopp when welding to the work piece.


2.Reduce power consumination, energy saving . Reduce the requirement of cables and lots of maintance cost.


3. Improve the power factor, reduce the production cost.


4. Reduce interference in secondary circuit which is in the large open area: the welding current is direct current. When there is induction or magnetic material in secondary winding, the welding will not be affected.


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