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.IMk.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.

Technological functions of rotary positioners control system

 

Controls:

  • 2 Step. This function requires the operator to press and constantly hold the foot switch or the button of the hand controller. Working cycle is started and when the foot switch or button of hand controller is released working cycle will stops. This is so-called two-motion mode. It can be active only if the Automatic rotation is not activated. Typical usage of this mode is welding when the operator sits so it is possible to immediately respond to the needs of welding rotation.

  • 4 Step. This function requires the operator to press and release the foot switch or the button of the hand controller. Working cycle is started and when the foot switch or button of the hand controller is press and release once again working cycle will stops. This is so-called four-motion mode. It can be active only if the Automatic rotation is not activated. Typical usage of this mode is welding when the operator is standing. That allows the movement at working place of the operator. Spindle is rotated uninterrupted.

  • Automatic rotation. This is a mode of automatic rotation checking. That means, the spindle is rotating by a predetermined angle from 0 ° to 730 °. By the pressing of the foot switch or the button of the hand controller the working cycle is started which is automatically terminated after reaching the predetermined rotation angle. The angle of rotation can be set in block "Rotation" in the MENU of WORKING PROGRAM, see below.

  • Low speed limit. Specifies the minimum adjustable speed of rotation (RPM) of spindle rotation in STANDBY MODE. I.e. the minimum rotation speed of the spindle from which the speed can be increased. Below this value set in this block the spindle can not be rotated. Therefore, if you want to use a full speed range of positioner, it have to be adjust to 0.001 rpm. Maximum adjustable value is always equal to the maximum possible speed of specific positioner, please see the production label.

 

Rotation:

  • Diameter. Adjusting of welding diameter. Control system R3 will automatically calculates the progressive welding speed - the relative feed rate of the torch. This value will be displayed in the STANDBY MODE on display screen. Settings in centimeters in the range from 0.0 to 300.0.

  • Rotation direction. Settings of direction in the rotation axis (Choice: Clockwise, or counterclockwise).

  • Rotat. delay. The function can be usefull for a better material melting before welding. Adjust the delay between switching ON of the welding source and starting of the spindle rotation. Settings in seconds with an accuracy to one-tenth in the range of 0.0 to 15.0 sec.

  • Angle of rotation. Choose the total angle by which the spindle will turns around its axis. The limit is 730 °. This function is active only when Automatic rotation mode is activated in block "Controls", see above.

  • End welding angle. It defines the point where the control system R3 switches OFF the welding source. Settings in angle degrees. Limit value is 730 ° but the total value can not be higher than the value adjust in the Angle of rotation. This function is active only when Automatic rotation mode is activated in block "Controls", see above.

  • Return to 0. It defines the returning of the spindle to initial position to find the starting position of welding =(e.g., directionally defined tools), or to unwrap the energy and gas hoses. This function is active only when Automatic rotation mode is activated in block "Controls", see above.

 

Gas:

  • Function is active only when the positioner is equipped by the valve for the switching of the gas (optional element).

  • Pre-gas. Serves to fill up the space of weldment root by protected – forming gas. It defines how long the gas valve will be switch ON before the system gives a command to ignition of the welding source. Settings in seconds in the range from 0.0 to 15.0 s. If 0.0 s is adjusted the function is inactive.

  • Pos-gas. It defines a time how long the valve will be switched ON after the command to switch OFF the welding source has come. Settings in seconds in the range from 0.0 to 15.0 s. If 0.0 s is adjusted the function is inactive.

 

Torch:

  • Function is active only when the positioner is equipped with a pneumatic arm for full welding automation (optional element).

  • Before welding. Choose the type of the movement of the torch to the welded product before welding process. (Choice: Automatically, i.e. torch will be incline automatically to the product when the working cycle is starts, or Manually, i.e. the torch waits for a command via the key on the control panel, before starting of the working cycle)

  • After welding. Choose the type of the movement of the torch from the welded product after welding process. (Choice: Automatically, i.e. the torch will be moved automatically from the product after the ending of the working cycle, or Manually, i.e. the torch waits for a command via the key on the control panel, after the ending ofthe working cycle)

 

Welded parts:

  • It can go about any part that fulfils the dimensional and weight restrictions of positioner without limitation of welding methods.

  • The welding process can take place at any angle of inclination of the spindle within the capabilities of positioner. This is completely unindependent on the eccentric load of the positioner by means of digital drive concept.

  • The control system is able to control the angle of rotation and the angle of switching the welding source off unindependently to each other. There is a possibility to reach the perfect connection of weld bead by the automated welding. Of course, there is a possibility of manual controlling.
