Factory directly supply MFDC spot Welding Power supply (MDDL series)
Character:
1,IGBT inverter with 4kHz frequency.
2,Three welding pulses with upslope and downslope.
3,Constant-current/constant-voltage/constant power/fixed pulse width control mode.
4,Upper and lower monitor of the current or the voltage etc.
5,Easily operating,.
6,Full I/O interface. The power supply can be easily used on a automatic machine.
7,Over heat false/wrong input voltage false/over control false.
Principle:
As the main circuit diagram below, the inverter welding power supply working principle is : (220V 50Hz AC)-----(310V 50Hz DC)-----(310V 4kHz AC)-----(5-18V 4kHz DC).
That is why the frequency being changed, because of the high frequency, the welder become more precision.
1, for 50Hz, we can only set 20ms welding time as a unit.but for 4kHz, we can set 0.25ms welding time as a unit, 80 times inproved.
2,when we do closed-loop constant control, the feedback speed is different, 20ms once by 0.25ms once, it is very much different.
AS the waveform of pulse DC current is flat, not like AC curve and around "zero"
We have compared that the DC power supply can sace more than 50% power than AC ones.
Advantages of inverter seam welding power supply and the current waveform of capacitor type/AC type/inverter type/crystal type
a,Inverter type of seam sealing power supply can saving 50% power than others.
b,Inverter type of seam sealing power supply can improve 3% stability than others.means less defective products.
c,Inverter type of seam sealing power supply can be much faster than others.
