May we help?
- What type of laser does the ALFlak 300 F use?
- The ALFlak 300 F uses a 300 W fiber laser with a wavelength of 1070 nm. It works in both pulsed and continuous-wave (CW) modes, offering 300 W CW power, 3 kW peak pulse power and 30 J pulse energy, with pulse durations from 0.2 ms up to CW and frequencies from single pulse to 100 Hz.
- How is the ALFlak 300 F different from the ALFlak 300?
- The ALFlak 300 F uses a fiber laser (1070 nm) that runs in pulsed and CW modes, while the ALFlak 300 uses a flash-lamp-pumped Nd:YAG laser (1064 nm) for pulsed welding. The two models also differ in laser characteristics and working-area dimensions, so check the specification table for each.
- What working range does the ALFlak 300 F offer?
- Its programmable X, Y and Z axes cover a movement range of 340 × 330 × 370 mm at speeds of 0–25 mm/s. The working height runs from 565 mm to 1780 mm, the arm deflection is approx. 1400 mm, and the welding spot diameter is 0.2–3.0 mm (0.1–4.0 mm optional).
- How is the ALFlak 300 F controlled?
- The machine is operated through a touch screen with WINLaserNC control. It supports programmable movement and teach-in functionality for repeatable welds, and a joystick-controlled movement system for accurate positioning of the laser processing head.
