WL-MF-50K Medium Frequency DC Welding Machine for Aluminium and Copper

 

DESCRIPTION

Medium frequency inverter DC resistance control system: Refer to the following picture, the three-phase AC current has been rectified into DC. Then convert into medium frequency 1000Hz square wave and connected into primary of welding transformer through inverter circuit which is composed of IGBT. After the rectification through welding transformer, the current become DC with small pulsation and being supplied to electrode for welding. The inverter will adjust the duty cycle rate of IGBT according to the feedback of primary and secondary welding current so as to achieve constant current during welding process.

 

Medium Frequency Pneumatic Dc Spot Welder For Copper Wire CE/CCC/ISO

 

APPLICATION

Sensor, LED and its lead, copper foil and vanished wire, relay, watch, capacitive slug and lead, copper wire, resistance pin, inductance, battery and stabilizer link, socket, silver contact and copper sheet, welding lightning with tungsten and molybdenum material, etc.

 

 

 

 

Compared with the normal AC controller, MF controller has the following advantages:

 

  1. Advanced welding machine, adopt principle of MF inverter . Change the three phase AC power into DC power.
  2. Welding current is DC , no inductance , higher heat input and output efficiency , more reliable and stable welding quality
  3. Three phase load balance, power factor is close to 1
  4. Intelligent digital controller, more precise and faster control of the welding current. The adjustment precision is 20 times higher than the AC machine
  5. Reduce the production cost, save energy, reduce the requirement for cables and maintenance cost, improve the induction factor.
  6. Store energy in a special inverter, more adaptation to the fluctuation of the power grid.
  7. Smaller size and lower weight of welding transformer, one third of the AC machine .
  8. Be able to weld aluminum and galvanized material product
  9. Especially suitable for welding three-layer metal sheet or very thin product

The Functions and Features of Control System:

The control system is composed of controller, medium frequency transformer, and welding work pieces. The controller contains controlled rectifier, energy stored part, IGBT, power source driver, and control center part, etc.

1) 101 sets of programmable welding models, 96 sets of seam welding models. Be able to select the model directly when welding;

2) The function of welding spot current increasing progressively, efficiently solve the instability of welding effect caused by current shunt when doing multiple points welding;

 

3) Be able to set the preheat current, welding current and tempering current, efficiently prevent the splash during the welding and work piece quenching after welding. The 3 electric pulses can be set separately and combine separately or freely;

4) Be able to slowly increase and decrease the current, effectively avoid the splash and defective nugget formation during welding. Be able to obtain excellent physical performance.

5) Be able to weld special material, special for welding Aluminum, galvanized metal and so on with ideal welding effect.

6) Counting function. Efficiently count the number of time of welding, number of use of electrode and grinding for better output calculation and machine management.

7) Function of Single spot welding , continuous spot welding;

8) Malfunction checking and self-protecting function. During working process, controller will automatically close the output current and friendly remind the reason of malfunction;

9) Energy saving, three phase power source output, high working frequency, low consumption of transformer, significant effect of saving energy;

10) Convenient installation and operation. In the MF inverter welding equipment, the volume of transformer has been decrease dramatically compared with common AC transformer. The whole machine is light in weight. Convenient installation and operation;

11) Communication and BCD code control function. Be able to connect to industrial personal computer, PLC and other upper control device so as to achieve remote control, automation management , with higher efficiency;

12) Adopt DSP and PLD as main control unit. The electric circuit is simple, high integrated, intelligent. Decrease the rate of malfunction. Easier maintenance.
