ELC 250 DUO – the multifunctional laser welding machine The ELC 250 DUO also works on the pick-up principle: the spindle loads itself and positions the workpiece where the welding optic requires or takes it to other processing modules. The ELC 250 DUO features two independent machining stations that share a single laser beam source; i.e. the laser beam is switched between stations. This increases productivity (cycle tome-concurrent component loading and unloading) and allows for the parallel machining of different workpieces or the inclusion of complex downstream machining operations (e.g. laser cleaning / joining / welding / brushing / checking). The result is optimal technological flexibility. The principle of a stationary optic allows for the integration of all laser technologies: the ELC 250 DUO can be equipped with either CO2 lasers or with solid-state lasers (fiber, disc). A number of different machining optics are available to suit a variety of requirements.
