Gas or water-cooled enclosed weld head OSK S + SW + GW

Open weld heads are clamped on one side of the weld joint. During welding, the gas- or water-cooled torch with hose package rotates around the tube. Advantages of open weld heads: — Robust design — Extremely easy to use — Option of using additional wire — Stepless tube size range — Torch bracket has 90° tilting function 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 OSW 275 \ OD 88.9 - 273mm \ 3.500" - 10.748" \ 16kg \ 1.3.1401 \ rotor can be decoupled Package includes: — Weld head — Integrated start/stop button on the handle — Top jaw — OSW torch bracket (with roll scanning in the case of OSW 275) — Mechanical headway control Optional: Angular gearbox 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 gas-cooled and compact weld heads. They are for smaller outside diameters with a narrow handle for tighter access conditions.

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...
