JK702H:  The accommodating laser system for your welding, cutting and drilling applications

JK702H Process Flexibility
The JK702H laser is particularly suited to microwelding, spot welding, or fine cutting and drilling tasks. It has 350 Watts typical power for a wide range of applications, such as:

  • Welding up to 2mm (0.08″) penetration
  • Welding with speeds up to 1.5m (60″)/minute
  • Cutting up to 4m (160″)/minute

Depth–and precision–are amplified with the addition of low-divergence resonator optics (optional) that distill laser output into a high-intensity spot, ideal for precision cutting:

  • Cutting and drilling up to 6mm (0.24″) in depth
  • Cutting and drilling with kerf widths or hole diameters down to 50 microns (0.002″)

Turnkey Machines
The laser can be tailored to an array of standard or customized turnkey multi-axis machining centers. Contact us for details.
NOTE:  Although the JK700 Series are Class IV/4 lasers, when equipped with safety enclosure they meet Class I/1 Safety Standards.
