LTK4 laser welders can be used for production of meters and precision instruments, for hermitic sealing of radio electronic equipment covers, press-molds repairing, stamping tools restoration and for other welding and building-up welding works associated with the production of electronic equipment, precision instruments, jewelry and medical devices.


Compact design. High durability and reliability. Delivery in complete sets. Turnkey solutions. Last generation components. Advanced ergonomic technologies and modern design:

  • Laser emitter has a dustproof cover. No resonator adjustment is required after lamp replacement.
  • Optical system. Includes a telescope with adjustable magnification and changeable lenses. Simple and convenient laser beam positioning in the weld area is achieved by means of a stereomicroscope with two-stage eye protection system. Allows double-channel laser spot sizing, adjustment of visual channel acutance and sizing of the laser spot by deepening the focus without changing the acutance of the visual channel. Camera pointing and monitoring system.
Power supply unit for lamp powering

Allows an extensive control over laser pulse energy, power and duration through regulation of pump lamp impulses amplitude, shape, duration and repetition rate.

Cooling system.

Double-circuit thermostable cooling system. Outer cooling circuit with service water.

Pneumatic system. Includes a set of gas nozzles, gas connectors and hoses, filter-regulator, electro-driven valves and rotameter.

Function modules include

Operators ergonomic work place equipped with a workpiece stage with T-slots for workpiece fixing and Z-axis precision motion mechanism; control units; pedal; lighting system.
