The contravariant power source is uses the IGBT inversion technology, the microcomputer control technology and the modern electric power electronic technology development new power source.Through uses AC-DC-AC-DC the transformation technology, the timing control achieved the millisecond level precision, causes the control to respond and controls the precision to enhance greatly; The direct-current output causes the welding technology capability remarkable improvement; The contravariant technology also enable the equipment to have, the energy conservation small highly effective and so on a series of merits; The micro controller and the electronic technology use causes this equipment to have the modern equipment outstanding function, inverts the power source to suit in the copper, the aluminum and so on the non-ferrous metal material spot welding, the alloy material spot welding, the precise components spot welding and the high grade product spot welding.
JIYI machine to invert the direct-current power supply characteristic:
1. By the micro controller (MCU) control, has the electric current, the voltage, the power monitoring function.
2. Uses the soft switch technology, reduces the switch to lose, reduces the electromagnetic interference.
3. Flows, the monitoring value abnormally ultra limits, the net presses ultra limits, superheat and so on the breakdown diagnoses with reports to the police the function.
4. Electric current abnormal automatic cutout, enhancement system protection.
5. The heating hypothesis, brings the electric current slow to rise the parachute approach function, the time width scope establishes (0-250ms), is suitable the complex welding process need.
6. The parameter storage, facilitates many kinds of welding variety use.
7. x128 LCD demonstrated that, simultaneously demonstrates many kinds of contents.
8. Exterior communication function: The welding finished, the breakdown, the counting signal, the RS-232 data communication mouth (match), is advantageous for welds the use automatically.
9. Moves the input signal (to start 15 groups to weld parameter most greatly), the output actuates 3 groups of signals, is advantageous for the multi-nose use.
10. Uses EEPROM, non-battery life question.
* The speed of response is quick.The circular telegram timing control cycle is 0.25ms, compared to usually exchanges welding machine 20ms to enhance 80 times
