Catalog excerpts

• Spot sizes down to 10 microns • Penetration depth beyond 0.06 in (1.5 mm) in metals • Fine, high quality cutting of metals • Excellent power stability • Simple, intuitive user interface • Touchscreen The LF Series fiber lasers offer the precise control needed for small component welding and fine precision cutting of metals. A large touchscreen pendant enables clear visibility of process schedule parameters, and an intuitive interface enables quick and easy programming. TYPICAL APPLICATIONS • Micro welding – The laser is available in either single or multi-mode configuration. Precise control of the laser's pulse width and peak power enables fine micro welding processes. Penetrations up to 0.06 in (1.5 mm) in steels, titanium and nickel alloys are possible using continuous mode operation. • Precision cutting – LF Series fiber lasers can achieve focused spot sizes down to 10 microns providing the ultimate non contact cutting tool. High beam quality and high frequency enable high speed precision cutting of a range of metals. Medical spring attachment • Spot and seam welding – 10 segment pulse shaping enables best quality spot welding results. Ramp up and ramp down feature controls welding results at overlap. • Excellent power stability – Fine applications require high stability of the laser 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. Medical component assembly • Touchscreen pendant – High definition 8 inch touchscreen pendant facilitates fast and intuitive laser programming. • Accessories – Full range of focus heads including inline, 90 degree with process viewing via a camera, and through the lens illumination options. Ultra compact heads are also available if space is a premium. Hypo tube cutting LASER WELDING
