Inverter spot welding and capacitor energy storage welding machine compares the advantages and disadvantages

Inverter spot welding capacitor stored energy spot welding machine

Current control of welding current into a pulse direct current, no AC zero without heating the workpiece defect.

Each welding Zhou Bo to 0.25 milliseconds (4kHz inverter frequency), automatic detection of output current every 0.25 milliseconds, to ensure consistency of output current,avoiding the subject to power fluctuations, avoiding weldcondition.

The control precision is high, the welding time can be controlled within N cycle. Capacitor energy storage welding machine energy stored in the capacitor once released to the welding circuit, output energy adjustment is completedby the charging energy control capacitance, usually adjust the charge voltage and capacity of two kinds of methods,the output current of pulse current, time can not beadjusted by electronic control. Current control is relativelyworse.

Long term stability without changing the core components,can ensure the long-term stable and consistent output current. To ensure consistency of welding. The core components of the capacitor is a consumable, need energyperiodic testing of capacitor charging, like like battery,laptop battery, with a period of time, also full of electricity,but the energy is not the same as. The need to replace thecapacitor.

Welding speed is fast, the actual output of up to 500 per minute of solder joint, solder joint maximum output per minute up to 1200 solder joints.

Supporting the automation welding equipment completely.Capacitor energy storage welding machine need reasonable capacitor charging process (or capacitance is easy to damage), reduces the production speed.

The energy-saving effect of inverter welding machinetransformer in the high frequency (1-4kHz), a very small DC output loss, improve power factor, energy saving effect is obvious.

Can save more than 50% energy. The actual work of the transformer capacitor energy storage welding machine at lower frequency, the greater the loss of transformer core,increase; capacitor charging circuit also increased loss.

The volume of the equipment and the weight of DC inverterresistance spot welder transformer is small, no capacitorgroup is huge, lightweight equipment. Capacitor energy storage welding machine transformer core is big, the energy storage capacitor also occupy considerable space,heavy equipment.

The service life of the electrode electrode loss is small, butconstant electrode loss is bigger

Price the price is slightly expensive (one time investment)slightly cheaper price. But requires regular replacementcapacitor, power capacitor expensive.

Reduce weld automatic line voltage compensation function,greatly reduce the weld and explosive phenomena.

To reduce the short welding time loss to the workpiece, the current through the electrifying time "joint several milliseconds -- tens of milliseconds, heat will not produce the" transfer to the solder joints around, reduce the loss on the periphery of the workpiece or a workpiece.

The characteristics of the machine

JYD liquid crystal display characteristics of series inverterresistance welding power source:

- DC output. The welding current is pulsating DC (andwaviness small), no AC zero discontinuous heating workpiece defects, concentrated heat, improve the weldingheat efficiency, especially suitable for welding non-ferrous metal materials and hard welding material, welding process stability and weld quality improved significantly. At the same time, electrode life extended.

- by micro controller (MCU) control, with current, voltage,power monitoring function.

Soft switch technology adoption - inverter bridge, reduce the switching losses and reduce electromagnetic interference.

Having current arrhythmias, monitoring value transfinite, netpressure overload, overheating fault diagnosis and alarm function.

- inverter current arrhythmias automatic shutdown, enhance the system protection.

- three section heating setting, with current slow rise and slow drop function, time wide range setting (0 250ms or 0 1s), the application of complex welding process needs.

240X128 LCD display, and display a variety of content.

- strong external communication: welding end, fault, the count signal and RS-232 data communication port(optional), convenient for automatic welding.

- data storage using EEPROM, no battery life.

- quick response. Due to the higher frequency (4kHz, 1kHz),the inverter frequency specific models of machine can refer to table 1. Power time control cycle is 0.25ms or 1ms,increased by 80 or 20 times than usual AC welding machine20ms, the control precision is obviously improved. With thecapacitor energy storage welding compared without charge and discharge, the controllability is obviously enhanced,especially suitable for precision parts welding and highquality, high precision, high speed welding.
