dc spot welder,
medium frequency welding
Medium Frequency Small Size DC Welding Machine for Electrical Copper Relay / Shunt
MF DC Inverter Spot Welder is one of the newest resistant welding technology
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 so the current is rectified in order to supply DC welding current.
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.
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.
1) Advanced welding machine, adopt principle of MF inverter . Change the three phase AC power into DC power.
2) Welding current is DC , no inductance , higher heat input and output efficiency , more reliable and stable welding quality
3) Three phase load balance, power factor is close to 1
4) Intelligent digital controller, more precise and faster control of the welding current. The adjustment precision is 20 times higher than the AC machine
5) Reduce the production cost, save energy, reduce the requirement for cables and maintenance cost, improve the induction factor.
6) Store energy in a special inverter, more adaptation to the fluctuation of the power grid.
7) Smaller size and lower weight of welding transformer, one third of the AC machine .
8) Be able to weld aluminum and galvanized material product
9) Especially suitable for welding three-layer metal sheet or very thin product
