Water-cooled orbital welding heads are designed for use under high thermal loads. The components that are primarily responsible for introducing heat into the system are cooled with a high water flow rate. The water-cooled orbital welding heads are universal and ideal for small spaces thanks to the slender design.

Water Cooled Weld Heads OSK CW
Universally applicable - thanks to its slim design, ideally suited for confined spaces. Our new generation of compact weld heads for high thermal capacities with a water-cooled collet housing and clamping levers. Both CW heads are operated using one handle and cable assembly.

Weld head | Tube size range | inch | Weight
OSK 21 CW | DA 3,17 - 21,3 mm | 0,125" - 0,839" | 1,0 kg
OSK 38 CW | DA 3,17 - 38,1 mm | 0,125" - 1,500" | 1,3 kg

Water Cooled Weld Heads OSK SW
Our new generation of three OSK SW weld heads – even narrower, technically optimised and redesigned. For very high thermal capacities, we also offer the gascooled S series weld heads in a water-cooled SW version (the structural width stays the same). The closed water cooling system covers the bottom collet housing area.

Weld head | Tube size range | inch | Weight
OSK 53 SW | DA 6 - 53 mm | 0,250" - 2,087" | 2,1 kg
OSK 76 SW | DA 6 - 76,2 mm | 0,250" - 3,000" | 2,6 kg
OSK 115 SW | DA 9,53 - 114,3 mm | 0,375" - 4,500" | 3,4 kg

Water Cooled Weld Head OSK GW
Weld head | Tube size range | inch | Weight
OSK 170 GW | DA 50 - 168,3 mm | 1,969" - 6,626" | 7,5 kg

Versatile use with just one drive unit
At Orbitec, the drive unit, hose package, and welding head are designed in a modular way. This allows various cassette welding heads to be operated with the same drive unit (except for the microfitting welding head). The result: reduced investment costs and greater flexibility in welding applications.

Optional:
- OSK S handle and cable assembly, 8m
- OSK SW handle and cable assembly, 8m (compatible with OSK GW)
- Div. collets OSK
