Inverter Resistance Welding Controller Advantages
As the graphs imply, our middle frequency welding control can output current in DC. Therefore, in using our welding controller, your welding process can be easier to control, your welding can be quicker, and your welding process can be more stable. The welding frequency of this machine is 1 kHz, so with a 50 Hz power source, the electric current adjustment process is faster and more accurate. So just as these graphs show, our middle-frequency welding control can control the electric output stably.


With regards to the general welding control, our middle frequency inverter resistance welding control system is more advantageous in the following areas:
1.The secondary welding circuit flow is in DC current. Therefore, due to this close connection for your weld project, the different degrees of depth produces the induction reactance of the secondary circuit that will allow your electric current weld to be more stable and its fluctuation greatly reduced. 
2.The weight of your required transformer can be greatly reduced.
3.Your electrode life can be longer.
4.Includes the ability to weld aluminum and zinc plated metal materials, etc., and its weld result is good.  
5.Is especially well suited for welding three-layered sheet metal, extremely thin materials, and very precise welds as required.
6.Creates fewer projectiles.
7.With our machine controls its electric current, the resulting quality of your spot weld will be improves greatly.  
Components of the Control System 
As the picture identifies, the components of the whole system includes a welding controller, a middle-frequency transformer, and your required components. Specifically, within the welding controller there contains more parts, such as a power driver, a rectifier diode, a capacitor, IGBT, and a central control component (Main-board).  
Welding Control Main features:
1.Power source output frequency: 1 kHz, with accuracy to the millisecond. 
2.Can program up to 15 welding schedules.  
3.Three section heating process: preheat, weld, and reheat; during the welding section process it is possible to set the welding control to increase heat gradually or decrease heat gradually. 
4.Has the capacity to program pressure controls, and can define at most 10 pressure sections.  
5.Has the capacity to program I/O output: within this, it can program 3 output sections, is more compatible with PLC, and can also program robot. 
6.Has a weld count function.
