Roto-Star III

The latest-generation
precision rotary benchtop
welding positioner

The ideal tool for a wide range of projects—
from pipe fittings to tubes and chassis

Like the Roto-Star I, the next-generation Roto-Star III enhances your weld productivity and quality. Its eight-inch-diameter three-jaw self-centering chuck accepts parts of virtually any length through its unique 2.5-inch spindle opening.

For larger stock, simply reverse the chuck jaws, and attach pieces that measure up to eight inches on the outside diameter.

For further flexibility, you can weld parts in the horizontal or vertical positions—or in 15-degree increments from 0 to 90 degrees.

Engineered for ease of operation

The Roto-Star was designed and created by a high-tech welder with years of real-world shop experience. You’ll greatly appreciate its easy, straightforward operation.

The state-of-the-art motor controller lets you vary spindle RPM and select forward or reverse rotation. The standard start/stop foot pedal quickly attaches to the controller, freeing your hands to concentrate on your weld.

The Roto-Star III is safely and securely grounded by a continuous brush contact on the back of the spindle. All drive gear and electrical controls are completely enclosed for operator protection.

Precision welds every time

The Roto-Star III is ideal for aluminum and stainless steel applications.

The heavy-duty motor runs on direct current and delivers smooth and accurate spindle rotation. Make positive starts and stops without coasting or backlash.

Durable and dependable

The heavy aluminum base of the Roto-Star III supports a variety of pieces and you can securely mount it to a grounded surface. The unit easily accommodates parts up to 200 pounds in the horizontal position and up to 250 pounds in the vertical position.

The Oilite spindle bushings also enhance durability by automatically lubricating the spindle with every revolution.

Most Roto-Star machines that were sold when the company was founded in 1994 still remain in productive operation today.

Optional 16-inch faceplate

The 360-degree rotation of the Roto-Star III enables continuous welds, eliminating unnecessary operator movement and repositioning of the material. If you’re welding large or irregular-shaped materials, we offer an optional 16-inch faceplate that easily attaches to the Roto-Star III.

The faceplate is machined from solid aluminum and provides a durable work surface that’s suitable for most welding applications. The faceplates feature reference rings for quick part positioning and tapped holes for secure clamping.

If you wish, you can order the Roto-Star III with the faceplate permanently attached, without a three-jaw chuck.

Optional motors

Like the Roto-Star I, you can order the Roto-Star III with a range of optional motors that deliver speeds from 1.5 - 48 RPM; the standard speed is 8.33 RPM.

Call us to discuss your welding requirements and we’ll incorporate the appropriate motor into your Roto-Star III. That will ensure that your unit delivers the optimal peripheral speed for your application.
