Pipe Welding Rotators CORMAK OS-3

Pipe Welding Roller Rotator CORMAK OS-3 – professional welding positioner for demanding users

The CORMAK OS-3 welding rotator is a high-quality welding positioner designed for precise rotation of cylindrical components during welding, assembly, and quality control processes. The unit combines robust construction, performance, and work ergonomics, making it an ideal choice for both heavy industry and specialised workshops. Thanks to its roller drive mechanism and load capacity of up to 3000 kg, the OS-3 model is perfect for welding pipes, tanks, and cylindrical steel components.

Main advantages of the machine

• Load capacity up to 3000 kg – enables operation with large and heavy components of various diameters.
• Universal diameter range of workpieces: 40–1400 mm.
• Compact dimensions and easy integration with other workstations.
• Rollers Ø250 × 50 mm – made of high-strength materials for stability and long service life.
• Foot pedal remote control – safe and convenient control without interrupting the welding process.
• Durable construction – enhanced resistance to dynamic loads, ensuring stability and operational safety.

Design and technology

The CORMAK OS-3 welding rotator has been designed with a focus on production efficiency. The frame is made of thick-walled welded steel profiles, providing torsional rigidity and long-term durability under industrial conditions. The rollers are mounted in precision-machined housings, ensuring stable and accurate support of the rotating component, which translates into high-quality welds.

Drive system

The OS-3 model is equipped with a reliable 0.37 kW motor providing smooth and uniform rotation. The drive enables precise adjustment of speed and torque, allowing the operator to adapt the rotation rate to the material type and thickness. The 230 V power supply allows connection under standard workshop conditions without the need for an additional three-phase installation.

Modularity and ergonomics

The compact construction allows for quick setup within production lines and easy repositioning in the workshop. The integrated foot pedal enables the operator to focus entirely on the welding process without the need for manual adjustments.

Precision and performance

The CORMAK OS-3 welding rotators are designed for maximum rotational accuracy and process repeatability. By eliminating vibrations and using a roller-based system, the device provides stable support for the workpiece along its entire circumference. This significantly reduces setup time, simplifies welding seam guidance, and eliminates errors caused by manual rotation.
