SATO-220 Open Head Orbital Weld Head

Achieve precise, deformation-free cuts with the AXXAIR 81M orbital cutting machine. Engineered with stainless steel concentric jaws, this machine prevents tube deformation, especially critical for thin-walled tubes, by securely clamping each piece for a consistent, perpendicular cut. The orbital saw moves smoothly around the tube, ensuring repeatable precision that minimizes the gap between tube ends, eliminating the need for additional facing and saving both time and costs.

Designed for flexibility, productivity, and portability, the 81M is an ideal tool for seamless tube-to-tube alignment in automatic and orbital welding applications. While the 81M focuses solely on cutting, other AXXAIR frames are scalable for beveling and welding use, enhancing versatility on-site or in the workshop.

  • The lighter design ECO range (powered by a speed-adjustable 1300W Metabo motor) consists of a stainless steel concentric clamping system with a large number of contact points, increasing the cutting range and quality and avoiding tube distortion.
  • The stainless-steel jaws guarantee protection from contamination of the tube.
  • The short blade-to-jaws distance reduces vibration, extends the blade life, and improves cutting quality.

AXXAIR offers a wide range of high-quality blades performing burr-free square cuts (< 0.25 mm / 0.01″ perpendicularity precision) and lubricant paste compatible with the ECO range machines.

Mark-free roller tracking ensures constant arc voltage without scratching the tube.

Precise axial alignment of the electrode thanks to the starwheel.

Versatile weld configuration with dual-axis torch adjustment.

Remote control for start/stop and electrode rotation.
