May we help?
- What type of laser does the ALFlak 300 use?
- The ALFlak 300 uses a 300 W flash-lamp-pumped Nd:YAG laser with a wavelength of 1064 nm. It operates in pulsed mode, delivering 9 kW peak pulse power and 90 J pulse energy, with pulse durations from 0.5 to 20 ms, frequencies from single pulse up to 100 Hz, and an adjustable power curve within each laser pulse.
- How long a weld seam can the ALFlak 300 make without repositioning?
- The ALFlak 300 can weld uninterrupted seams of up to 340 mm. Its programmable X, Y and Z axes cover a movement range of 340 × 320 × 420 mm at speeds of 0–25 mm/s, which reduces the need to reposition the machine.
- Can the ALFlak 300 reach large components and deep moulds?
- Yes. The projecting laser arm offers 1500 mm of arm deflection and a working height from 200 mm up to 1500 mm. The machine is available with a self-propelled caterpillar track or as a manually movable version, so it can be brought to large workpieces.
- How is the ALFlak 300 programmed and controlled?
- Movement is programmed through WINLaser 5 software with teach-in functionality. Operators set laser parameters, movement and axis speeds on the touch display, position the processing head with a precision joystick, and adjust laser parameters during welding using the patented multifunctional footswitch.
