TINKER 70 is an ergonomically designed rotary welding positioner of a table design with a maximum load capacity of 70 kg. It is a simple yet highly effective positioner specifically designed using only first-class constructional components. This machine provides an ideal solution for smaller weldments where smooth rotation, stable speed, and a clean welding result are essential, with particular emphasis on the hollow spindle for welding long rod material.
A high-quality steel frame carries the structure of a massive spindle with a through-hole of 78 mm. The spindle design allows comfortable use of a working plate with a maximum diameter of 425 mm as well as a 250 mm universal chuck with a through-hole of 78 mm.
Control system R3 is integrated into the machine chassis and protected by a steel cover with the polycarbonate glass cover against splashes of welded metal. The positioner has a table design for placement on the edge of a working table, allowing the hollow spindle to be used when welding long rod materials. The hollow spindle can also be used to equip the machine with an integrated system for supplying inert gas through the spindle.
The rotary positioner is equipped with a quality stepper drive and a backlash-free planetary gearbox, ensuring perfectly smooth and constant rotational speed even under eccentric loads from the welded product to achieve a consistent weld around the entire circumference of the product. The precise combination of a stepper drive, planetary gearbox, and digital control also ensures repeatable return to the same home point without deviation.
Operation of the positioner can be made easier by using the foot controller for proportional speed regulation, which allows the spindle rotation speed to be adjusted during welding. A hand controller is another alternative for remote control of the positioner. In addition to controlling the rotation speed, both the foot controller and hand controller may include a selector for changing the rotation direction.
The spindle has a variable tilt range of 0 - 110°, ensuring the optimal welding position. The spindle tilt is adjusted manually by a gearbox and a handle located at the front of the machine, allowing the tilt to be changed even when the welded product is loaded.
The positioner has integrated anchor points for the installation of a supporting column, which enables the positioner to be equipped with an advanced welding arm system. The welding arm has pneumatic control and three degrees of position adjustment.
At the end of the welding arm, there is a precise mechanical cross head for two-axis torch position adjustment in the range of +/- 15 mm. It features a backlash-free structure and allows the torch to be rotated by +/- 90° and tilted within a range of +/- 20°, with both movements featuring position locking in steps.
This rotary positioner is equipped with digital control system R3, specially designed by HST CREATIVE for circumferential welding and effective automation of this process. The positioner also has a controlled output for switching the welding source arc ON.
