> Web version: https://qovolt.com/en/productos/quantum/q5a · Updated: 2026-06-17

## Summary

The QOVOLT Q5A (QUANTUM AIR LASER) is a 1500 W air-cooled fiber laser welding machine with IP55 protection. It runs on 230 V AC 1 phase (180–270 V), with a 100 % @ 40°C duty cycle and a 1080 nm wavelength. Welding capability: stainless steel up to 5 mm; carbon steel up to 5 mm; galvanized sheet up to 5 mm; aluminium up to 4 mm; brass up to 4.5 mm; copper up to 1.5 mm. It weighs 46 kg and measures 650 × 280 × 575 mm.

1500 W air-cooled in a compact, single-phase unit. Ideal for manufacturers requiring consistent industrial productivity without the complexity of a hydraulic system.
