Precise resistance soldering machine WZ-04LB

Quick Overview
Spot Soldering System

Precision resistance welding machine using AC-DC-AC-DC conversion technology to implement DC spot welding, compared to frequency AC spot welding technology, DC spot welding high quality, fast welding, energy saving effect, small size, light weight equipment. Using the MCU precise control of welding process, real-time monitoring and display the current welding current and other parameter values.

Inverter resistance welding power supply: DC output. Welding current is pulsating DC, waviness is small, no AC zero cross-heating workpiece shortcomings, heat concentration, improve the thermal efficiency of welding for non-ferrous materials and some difficult welding of welding materials particularly suitable for welding process stability, welding quality Significantly increased. At the same time the electrode life has been extended.By adjusting the size of the air pressure to control the soldering pressure
Using AC-DC-AC-DC conversion technology, making the time control can reach milliseconds and accuracy, control response and control accuracy has been greatly improved.Inverter bridge current automatic shutdown, and enhance system protectionCurrent soldering waveform>
Separate increase pressure adjustment knob:Together with the air pressure to adjust the soldering pressure.Throttle valve: By controlling the cylinder throttle valve to adjust the rise and fall speed
Electrode: The electrode is made of tungsten alloy, has a strong high temperature hardness and strength, at room temperature and high temperature environment has good electrical conductivity and thermal conductivity. And strong antioxidant capacity. Customized soldering electrodes Customized fixture
Three-stage heating setting, with the current slow rise and slow down function, the time is set to (0-250ms or 0-1s), suitable for complex welding process needs.The soldering current is displayed on the LCD screen in real time

Current upper and lower limit setting interface, real-time monitoring current current is beyond the se tting range


Warning interface: Displays the current error
