Medium Frequency DC Welding Machine for Electrical Copper Relay / Shunt
Description Of Medium Frequency DC Welding Machine
MF DC Spot Welder is one of the newest resistant welding technology.
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.
 | Intelligent welding control system Intelligent Touch Screen Controller
Input and read welding parameters. |
| Raw materials made to standard Thicker Copper Plate or Copper Belt
To ensure stable conductivity in welding |
|  | Custom processing of electrodes Customized Electrodes which will be suitable for Welding material like steel,, silver, stainless Steel, and nickel steel. |
Feature Of Medium Frequency DC Welding Machine
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) Intelligent digital controller, more precise and faster control of the welding current. The adjustment precision is 20 times higher than the AC machine.
4) Reduce the production cost, save energy, reduce the requirement for cables and maintenance cost, improve the induction factor.
5) Store energy in a special inverter, more adaptation to the fluctuation of the power grid.
6) Smaller size and lower weight of welding transformer, one third of the AC machine .
7) Be able to weld aluminum and galvanized material product.
8) Especially suitable for welding three-layer metal sheet or very thin product.
