Three-phase Medium Frequency DC Welding Machine

DESCRIPTION

(1).Welding current for the DC ,when the secondary windings in the induction/a magnetic 

      material will not be affected by welding.

(2).So that the load-balancing power supply      equipment :frequency inverter welder convex 

      point on the use of three-phase power grid voltage drop fluctuations and greater adaptability.

(3).More precise ,fast current control :frequency systems and more ,a more accurate analysis of 

      parameters.

(4).Faster to set up current :IF in the regulation of welding current technology faster than traditional 

      20-fold.

(5).Process more reliable :the majority of the application of solder DC welding metal effect will be even 

      better.

(6).Reduce operating costs ,including energy savings each and every point of welding as well as 

      shortening the welding cycle.

(7).Save energy :especially suitable for welding thick workpieces and high-conductivity metal.such 

      as aluminum and galvanized steel sheet, etc.

FEATURE

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

2. In a semi-automatic machine, one medium frequency transformer can replace many low frequency transformers which can help to reduce the parallel connection in secondary circuit.

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 spot/projection welder adopts the three-phase sources which can store energy.

6. More adaptable to the fluctuation of power grid and voltage drop: a part of the energy has been stored by inverter and been supplied to load. It replaces the way of power supply to load directly from the power grid.

7. More precise and fast control of current: Compare with low frequency system, it is able to analyze more parameters in a more precise way.

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

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

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