Inverter spot welding power supply

Specification:

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.

Actual waveform:

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.

ABOUT PACKAGING:

First we use foam and paper package,and second we use plywood box to cover, ensure there willl be no 

injury during delivery. as below:

ABOUT SHIPPING:

First, usually we quote an EXW price, the shipping method should be discussed. we have tried fast forward 

as DHL, and have tried by air, and by land to Russia, also by sea. also we are glad to support customer's own

forwarder.

      Guangzhou Minder-Hightech Co.,Ltd(MINDER-HIGHTECH CO.LIMITED HONGKONG ) is focused on connection(welding).

      We are comprised by a group of high educated specialists,with the leader of overseas professor, some of us have more than 20 years welding experience,our goal is to provide high performance product but low price and exceeded service.

      We care for the safety of operator, this year, we developed a safety system in spot welding industry named SOFT TOUCH system,which can prevent heavy pinch point injury.

      We are specialized in most of the connection(welding) technics,the most application we have participated in are electronic component(resistance,capacitor,inductor),chip on board,automotive electronic accessories,cell phone,IC cards,motor armature commutator etc.By material, we have engaged in connecting the Aluminum, Copper, Brass, Au(gold), Platinum, Nickel, Enameled wire, etc.

       We also provided the full IC package line; and LED producing line; Crystal oscillator producing line; as well as the wafer machining equipment.

       Our product are classified into resistance spot welding,inverter seam welding, ultrasonic wire bonding,hot bar soldering,automatic TIN soldering,stud welding, all the product are with mature latest technology,high performance,high precision,and high reliability.

       At the same time, we maintain a good relationship with the high school scientific research institution,we know the newest connection(welding) technology direction all over the world, committed to give out the best connection(welding) solution to our global customer.

       We chose the most open and industrialized city-guangzhou-to be our base head place,to ensure the efficiency and rapidly response.

       These years,we proud of our growth with the famous company such as TPT,K&S,ASM,Bosch,Miyachi,Uniteck,Avio,Apollo,LPKF etc.
