Fiber Laser Welders - 100W - 500W


  • Focus spot sizes down to 10 microns
  • Penetration depth beyond 0.06” in steels
  • Fine, high quality cutting of metals
  • Excellent power stability
  • Simple, intuitive user interface


Drawing on its extensive experience in pulsed Nd:YAG micro welding, Miyachi Unitek introduces its LF range of fiber lasers, which offer the precise control needed for fine cutting, small component welding, and penetration welding of metals. A large touchscreen pendant enables clear visibility of process schedule parameters, and an intuitive user interface enables quick and easy programming.

Fiber laser sources from 160 to 1000W are available in both single and multi-mode configurations and may be operated in either pulsed or cw mode ensuring application across a broad range of production requirements.
