HWASHI WL-MF-250K Vertical Type Metal Sheet Medium Frequency Inverter Spot Welding Machine
DETAILED DESCRIPTION
1. MF Inverter Spot Welder is an advanced welding equipment. The three-phase power supply, through rectified by a special inverter, is converted into 1000Hz AC voltage and then is transmitted to a medium frequency transformer then the current is rectified in order to supply DC welding current.
2. The advantage is that it helps to greatly reduce the energy of iron core material, as the frequency of welding transformer is promoted from 50/60Hz of mains supply to 1000Hz. Besides, the commutation diode of subloop of transformer could transform the electric energy into DC power which is used to provide power for welding.
3. Under such circumstance, the inductance coefficient of subloop could be improved dramatically and the production cost could be minimized because the inductance coefficient is an important factor that results in energy loss but could almost be ignored in DC welding circuit.

Feature
1. Three-phase power supply, grid balance, small impact on the grid
The power factor is as high as 0.7-0.9 (power frequency 0.4), which greatly reduces the reactive power loss.
2. Significantly improved welding control accuracy
The inverter frequency reaches above 1000Hz, and the welding current control ability and control accuracy are 20 times higher than those of AC welding machines.
3. Great leap in welding quality
The current waveform is straight, the size of the nugget is stable, the spatter is less, and the surface quality of the solder
joint is good.
4. Save basic investment and save energy
The grid power demand is low, only 2/3 of the AC resistance welding machine; the welding time is short and the electrode life is long.
5. Human-computer interface, easy to operate
Multiple sets of welding specifications can be stored and called with one key, real-time display of welding current and time, monitoring and alarm functions of welding pressure, cold water flow, and welding current.
