Rotary welding positioner of table design intended for circumferential welding in metal workshops and light industry also with high hourly loading.

Rotary positioner is equipped with quality drive guarantees perfect smoothness and constant rotate speed even under eccentric loads by welded product. Each HST CREATIVE rotary positioner is equipped with digital control system R3 specially designed for circumferential welding and successful automation of this process, the positioner also has controlled output for switching the welding source.

• RWP 425.91, version Mk.I, is rotary welding positioner of table design with 370 mm working height and maximum working load of 90 kg. It goes about simple but high effective positioner with specific design using solely first class constructional components.

• Positioner can be supplied in three production versions - Mk.I, Mk.II, or Mk.III. The spindle speed range for Mk.I version is set higher for rather lighter products of smaller diameter for rotation at higher speed however less torque is available. The Mk.II version has universal torque and spindle speed range for use with the standard sizes of welded products. The spindle speed range of Mk.III version is set lower. However higher torque is available for use with bulkier products of larger diameters with weight closer to the maximum allowed loading of the positioner. Therefore the choice of version should depend on the expected use.

• The rugged stell construction carries the spindle which allows using the working plate and universal chuck comfortly. Control system R3 is integrated into the positioner chassis and protected by steel cover with the polycarbonate glass cover against the suppression of the welded metal.

• The work with positioner can be easier while using the foot speed rotation proportional controller which allows to set the speed of spindle rotation. Hand controller is another alternative for the remote control of the positioner. In addition to controlling the speed of rotation both, the foot control and hand controller, may include a selector for the direction of rotation.

• The spindle has a variable tilt features  0 - 110° ensuring the optimal welding position. Tilting of spindle is driven manually by gearbox and it is possible to change the tilt also when the welded product is loaded.

• The positioner has integrated anchores points for the installation of arm which enables automized operation of the positioner and can be equipped with the pneumatic system of the arm of the welding torch. The torch arm has pneumatic stroke and four degrees of release. At the end of the arm there is precise support of the torch position with backlash-free adjustment in two axes +/- 15 mm and the possibility of rotation by 90° with position locking. The torch holder can be designed for MIG or TIG torchs (others are on request).

• HST CREATIVE rotary positioners are suitable to use for MIG/MAG and TIG welding methods including pulse arc welding and plasma welding.
