We produce a unique electron beam generator with precise beam control.
- Easily exchangeable cathode.
- Easy and fast procedure for replacing the cathode.
- Precision device for mounting the cathode (cathode mounting tool).
It consists of 2 main parts:
1) Electron gun for particularly precise beam control. Equipped with triode with a direct heated tungsten hair pin, ribbon-type or LaB6 cathode to form an axisymmetric electron beam with a small crossover, providing a circular focal spot shape during welding.
2) High voltage power supply delivers the continuously adjustable beam voltage from 5 to 60 kV (Minimum step size is 20 V). Due to the pulse mode, MICROBEAM is able to perform precise energy and heat transferring
