Operation
Due to the revolutionary welding system, any user can achieve good working results after just a short training.
The electrode feed cable allows the welder to work freely at multiple stations without having to relocate the device. The small heat affected zone prevents excessive distortion. The weld is placed very simply and quickly, creating a robust joint.

Application
The laser welder is designed for professional use in facilities requiring high-quality and aesthetic welds.

Structure
The gun cable ensures high freedom of movement making it easy to weld in different positions. The built-in controller with a large, transparent display is operated intuitively. The device is equipped with a powerful cooling system which allows it to work under harsh conditions in three shifts.

Pronciple of operation
The laser welding machine melts the welding wire and part edges using laser heat. Once the device is started and set up, the welding gun is applied at the beginning of the future welding line. Then, when the handle trigger is pressed, the beam is produced in the source and fed via a fibre optic cable to the gun head. The beam is focused and emitted towards the welding wire which feeds (via a feeder) to the contact point. Then, when the trigger is activated, the gun must travel along the welding line according to the wire feed rate. A water-circulated cooling system ensures a constant operating temperature of the source and gun. Radiation emission levels and cooling are controlled by a controller which adjustes the values according to user parameters.
