In order to capitalize on the full potential of the PWS (Profile Welding System), most of the lasers used are high-performance units with excellent beam quality. The CO2 Slab Lasers in the Rofin DC range are unbeatable in this field. Rofin unveiled the DC 080 W,  the most powerful model of the tried and tested range of Slab Lasers. The laser on show is the “compact” version with integrated control cabi-net. With 8 kW output power and an excellent beam quality of K ? 0.9, this laser really proves its worth at high process speeds, where it can be used for welding pipes and profiles, amongst other things.
For applications which need wider welded seam widths, the DC 080 W is also available with an optional DONUT mode. This mode enables a focus diameter which is enlarged by a factor of 2 while keeping the focusing length the same. This means an increased melted volume in order to compensate component tolerances.
ROFIN´s low-maintenance CO2 Slab lasers are extremely service-friendly thanks to the trend-setting principle. The laser operates with only a few extremely durable components and does not need conventional gas recirculation – leading to a con-siderable reduction of maintenance and service. The gas consumption is also minimized. The laser beam that is produced in the resonator is uncoupled by a diamond window without any losses of power or beam quality. The internal water-cooled mirrors are robust and non-wearing reflective optics.
