Rotary welding positioner of stand design intended for circumferential welding in metal workshops and 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 550.371 is rotary welding positioner of stand design with 1010 mm working height and maximum working load of 370 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. Laterally the rack-mounted power tilt spindle is fixed to which the self-locking screw gear is assigned. Control system R3 is integrated into the machine chassis and protected by the 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 positioner. In addition to controlling the speed of rotation both, the foot control and hand controller, may include selector for the direction of rotation.

• The spindle has variable tilt features  0 - 90° ensuring the optimal welding position. The spindle tilting has motor drive and is possible to change it manually.

• The positioner is equipped with an integrated flange for mounting the welding arm which enables automatic operation of positioner and can be equipped with pneumatic system of the arm of the welding torch. The construction is created in such way that the position of the arm can be changed by the tilting of the spindle.

• The torch arm has a 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 torches (others are on request).

• There is the possibility to deliver the positioner with integrated system for divorcing the forming gas through the spindle.

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