COAX 12

The basic assembly of the COAX12 nozzle is similar to the COAX8 type. But, instead of a ring slit, four separate powder streams are directed onto the working point. They form a homogeneous powder spot, which is nearly independent from gravity. Thus, the powder supply is independent from the welding direction as well as from the inclination of the laser head. So nearly any desired contour can be generated, and nozzle inclinations do not influence the powder supply. Even working in three-dimensional space with moving nozzle is possible.
