Gas- and Water-cooled enclosed weld head OSK S | SW series

The open-frame weld head locates one side of the weld joint. During welding, a gas or water cooled torch and cable assembly rotates around the tube or pipe. Some advantages of open-frame weld heads: - Robust construction - Ease of handling - Option to add wire feed - No ‘size specific’ collets required, each weld head will accommodate its full tube/pipe OD size range as supplied - 90° tilting torch bracket Weld head | Tube size range mm | inch | weight | item number OSW 40 | OD 8 - 40mm | 0.394" - 1.575" | 2kg | 1.3.1001 OSW 80 | OD 10 - 76.2mm | 0.394" - 3.000" | 3kg | 1.3.1101 OSW 115 | OD 20 - 114.3mm | 0.787" - 4.500" | 4.5kg | 1.3.1201 OSW 170 | OD 40 - 168.3mm | 1.575" - 6.626" | 6.5kg | 1.3.1301 Package includes: - Weld head - Integrated start/stop-button at the handle - Clamp ‘shoes’ - Torch bracket - Mechanical arc gap adjusting screw Optional: Angular gear complete for OSW on request

Gas-cooled weld head for applications with extreme narrow space requirements as e.g. in the semiconductor industry. Specially designed to weld micro-fittings. Unique construction, including specifically directed gas routing to improve gas coverage and material selection resulting in a high duty cycle even without water cooling. — Extreme narrow / compact design — Simple design allows easy to maintain — Weld Head compatible with control element (start/stop kit with status display) — Arc Machines Model 9-500 cassettes will fit too

Our latest series of 2 gas-cooled and compact weld heads. They are for smaller outside diameters with a narrow handle for tighter access conditions. Weld head type | Field of application mm | inch | weight | item number OSK 21 CS | OD 3.17 - 21.3mm | 0.125" - 0.839" | 0.8kg | 1.0.2820 OSK 38 CS | OD 3.17 - 38.1mm | 0.125" - 1.500" | 1.2kg | 1.0.2920 Our new generation of compact weld heads for high duty cycle requirements have watercooled clamp housings and clamping levers. Both OSK CW weld heads are operated using a sharable handle and cable assembly. Weld head type | Field of application mm | inch | weight | item number OSK 21 CW | OD 3.17 - 21.3mm | 0.125" - 0.839" | 1.0kg | 1.0.2820W OSK 38 CW | OD 3.17 - 38.1mm | 0.125" - 1.500" | 1.4kg | 1.0.2920W Only one drive unit is needed for all C and CW weld heads.

The RBK 60 S is an extremely robust water-cooled weld head for a standard heat exchanger application up to an ID of 60 mm, modified to an ID of 99 mm or 120 mm. The head is pneumatically centred and is available with a rotating wire device and/ or arc voltage control (AVC) as an option. The head can also be used with a pneumatic positioner instead of a balancer. Versions: — RBK 60 S weld head with pneumatic centring, including hose package, 8m, water-cooled — RBK 60 S weld head with pneumatic centring and wire feeder incl. hose package, 8m, water-cooled — RBK 60 S weld head with pneumatic centring, wire feeder and AVC incl. hose package, 8m, water-cooled Package includes: — Weld head — Small torch incl. torch consumables and tungsten electrode Ø 2.4 mm — Water-cooled hose package, 8 m — Pull bar B — Transport case Optional: — Div. spring sleeves and pull bar sets for RBK 60 S — Torches, Balancer, Tube-to-tubesheet positioner...
