Precise resistance soldering machine WZ-04LB

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 protection Current soldering waveform
