Led Pcb For Welding Machine
This Led Pcb For Welding Machine product is developed for miniaturization of pure argon arc welding machine, suitable for all kinds of household type, with miniaturization modular have characteristics. This inverter adopts IGBT control technology, constant current characteristic, high accuracy of current control, and can be started within 5 arcs with a success rate of 99%.
-Reduce the loss of workpiece: Welding time is short, the current through the solder joint electrification time "a few milliseconds -- dozens of milliseconds". The heat generated will not transfer to the solder joint around, thus to reduce the loss of the workpiece or workpiece around.
-Good solder joints: Led Pcb For Welding Machine has the advantages of small welding spot, firm welding, small oxidation and no blackening.
