Middle Frequency Inverter DC Pneumatic Spot Projection Welding Machine
Features:
DN Series Middle Frequency DC Inverter Spot & Projection Welding Machine is an advanced welding equipment..welding transformer small size and large energy output,it is widely used.it is specially used in transformer welding clamp style of car industry.and its superior performance is because of their welding transformer frequency from the city electricity 50/60 HZ uggrade to 1000 HZ, greatly reducing the weight of the core material, moreover,the rectifier diodes in the sub-circuits of the transformer make the energy into DC power supply for the use of welding supply.This will greatly improve the value of induction of sub-circuits ,which will minimize the cost of production
In the big open area of the secondary circuit can reduce interference: welding current to direct current, when the secondary winding in the induction / a magnetic material, will not affect the welding
So that the load-balancing power supply equipment DN invert spot and projection welding machine used three-phase power and energy can be stored
Fluctuations in the power grid and the pressure adaptability should be more: part of the energy storage inverter to supply load, replacing the way of power grid directly from the power supply to the load .
More accurate and fast current control : compared with the frequency system can be more accurate analysis of parameters
Faster to set up current: MF in regulation welding current can 20 times faster than traditional technology
The process more reliable: Most of the metal used resistance welding would be better to use direct current welding.
Reduce operating costs, including energy savings every point of welding and shorten the cycle of welding.
Energy savings: Compared with the use of the frequency can reduce electricity consumption, adapted to welding the thick workpiece and high-conductive metal. Such as aluminum and galvanized steel sheet, and so on.
