LF Series - 160-1000W Yb:Fiber Laser Welders

The LF Series fibers lasers offer the precise control needed for small component welding. A large touchscreen pendant enables clear visibility of process schedule parameters, and an intuitive interface enables quick and easy programming.

Key Features:

Integrated laser system - Complete system with laser engine, controller, touchscreen interface and chiller (if necessary) integrated into chassis.
Micro welding - The laser is available in either single or mulit-mode configuartion. Precise control of the laser's pulse width and peak power enables fine micro welding processes. Penetrations up to 4 mm in steels, titanium and nickel alloys are possible using continuous mode operation.
Spot and seam welding - 10 segment pulse shaping enables best quality spot welding results. Pamp up and reamp down feature controls welding results at the ends of seam welds.
Excellent power stability - Fine applications require high stability of the lasere source for reliable processing. The LF Series offers excellent power and pulse to pulse stability with an internal air-to-water cooling mechanism which maintains stability irrespective of ambient air temperature.
Accesories - Full range of focus heads including inline, 90 degree with process viewing via a camera, and through the lens illumination options. Galvo heads are also available. Ultra compact heads are available if space is a premium.
