Specifications
The Main unit comprises the following:
- Main Laser Welding Machine (SR – LWL – 2L/F2500)
- Welding head with 3-axis linear system (x & y axes servo motor driven – z pneumatically driven).
- Servo motor rotation of the welding head from 0 to 180o around the z-axis (horizontal plane).
- One off Welding table with manually adjustable positioning limits for the sheet and the frame to be welded as well as a manually operated clamping system.
- 2 TRUMPF Tru Pulse 556 Laser Device with 2 Laser light cables.
- Laser Class 1 Protection.
The main Machine can be outfitted with the following optional extras:
- Water Chiller, to cool the Laser Device. It is necessary only if adequate in-house cooling means do not exist. Required cooling capacity is 30 kW for both Laser Sources
