Catalog
New generation. Handheld fiber laser welding.
The Cheetah Air Mini series: fast, low-distortion laser welding with an integrated wire feeder and a precision aluminum torch. Cheetah L (water-cooled) is coming soon.

Cheetah Air Mini 3 / 5 / 7
Same torch, same wire feeder, same air-cooled setup — the number tells you the rated single-pass penetration depth and the power behind it.

Engineered in-house
The Cheetah torch, built for a higher standard.
Every Cheetah Air Mini ships with the same precision handheld torch: a CNC-machined, aircraft-grade aluminum body, an integrated status indicator light, and an industry-standard QBH interface — so it feels identical in the hand whether you're running the 3, the 5 or the 7.
Aircraft-grade aluminum
CNC-machined aluminum torch body — light in the hand, cool to the touch, built to survive the shop floor.
Integrated status light
A built-in indicator light on the torch head shows ready / active state at a glance, without looking back at the machine.
QBH quick-connect
Industry-standard QBH interface for a fast, secure fiber connection and simple field servicing.
Precision optics train
Collimating and focusing lenses, a copper nozzle and a calibration tube deliver a consistent, repeatable weld spot.
