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.
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:
| Touch Screen | Central part of operation for input data, monitoring and storage |
| Solenoid Valve Switch | Manual switch on or off |
| Emergency Stop Button |
When start, it will end the entire running program. Note: after pressing this button, you need to power on the machine again. |
| Reset Button | After stopping the program, press this button to reset. |
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.
