JK702H: Your 350W laser system
for welding, cutting and drilling
• Offers 350 Watts average power for a wide range of applications
• Optional low divergence resonator optics for concentrated
power, ideal for precision cutting
JK702H Process Flexibility
The JK702H laser is particularly suited to microwelding, spot welding, or fine cutting and drilling tasks. It offers 350 Watts average power for:
● 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 increased by the addition of low divergence resonator optics (optional) which concentrate laser output into a high intensity spot for:
● 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 also be fitted to a broad range of standard or customized turnkey multi-axis machining centers. Details provided upon request.
NOTE: The JK700 Series are Class IV/4 lasers–but when supplied complete with safety enclosure–they meet Class I/1 Safety Standards.
