The air laser welding machine utilizes a self-generated gas mixture of 99.99% argon-nitrogen gas. The gas generator employs a multi-stage vortex collision separation filtration system imported from South Korea, featuring a high-precision gas production unit. This ensures a pure and stable gas supply while significantly reducing operational costs. The handheld welding head comes standard with a 10-meter fiber optic cable, enabling flexible and convenient long-distance outdoor welding. Beyond single-wire and dual-wire feeding modes, the air laser welder can also utilize a stepper quad-wire feeder to achieve triple-wire stack welding.

Kempson air fiber laser welding machines combine laser welding with self-generated shielding gas to deliver efficient, stable, and high-quality welds. The working principle is as follows:
First, an integrated high-precision gas generator produces high-purity inert shielding gas. Select models feature multi-stage vortex filtration systems to ensure stable, pure gas without external procurement.
The laser outputs high-density beams via a custom-designed chip. Energy is precisely focused onto the weld zone through a rotating anti-spatter torch, rapidly melting the base material and filler wire to form a robust weld.
Managed by a Schneider Electric control system, the equipment supports dual-wire feeding and step control, suitable for single- or double-sided welding of plates ranging from 0.5 to 10 mm thick.
During welding, self-generated shielding gas isolates the weld zone from air, preventing oxidation. This ensures spatter-free welding with low energy consumption, high efficiency, and stable performance.
