OVERVIEW

Precision Circle Cutting Made Simple

Take the hassle out of cutting perfect circles with the Thermal Dynamics 7-3148 Magnetic Pivot Kit. Designed as an optional upgrade for the popular Thermal Dynamics Circle Cutting Guide Kit (7-3291), this magnetic base is a game-changer for anyone working with steel. Instead of measuring, marking, and drilling a pilot hole for your circle guide, simply place the magnetic pivot on your center mark, and you are ready to cut. It holds firm against the metal, providing a rock-solid anchor point for your plasma torch.

Why Choose a Magnetic Pivot?

Time is money in the fabrication industry. The 7-3148 kit significantly reduces setup time by eliminating the need for center drilling. It also expands your capabilities, allowing you to cut circles on finished surfaces where a center hole would be unacceptable. The magnet is powerful enough to resist the lateral pull of the torch hose and the movement of the guide bar, ensuring that your circle starts and ends at the exact same point. This level of precision reduces the need for secondary grinding or cleanup, streamlining your workflow.

Designed for Thermal Dynamics Systems

This kit is manufactured to the high standards you expect from Thermal Dynamics. It integrates seamlessly with the 7-3291 guide system, which is compatible with a variety of Thermal Dynamics plasma torches. The pivot rotates smoothly, allowing for fluid motion throughout the 360-degree cut. Whether you are a professional welder, an artist working with metal, or an industrial fabricator, this accessory provides the stability needed for high-quality plasma gouging and cutting.

Essential for Steel Fabrication

Please note that because this unit relies on magnetism, it is designed for use with ferrous metals like mild steel and carbon steel. It is an indispensable tool for tank fabrication, pipe saddle cutting, and general plate work. The kit includes the magnetic base assembly and necessary hardware to attach it to your existing guide bar. Enhance your shop's efficiency and precision today with this genuine Thermal Dynamics accessory.

FAQ

The 7-3148 is used to anchor the center point of a circle cutting guide using a magnet instead of a pin, allowing for circle cutting without drilling holes in the workpiece.

This kit is specifically designed to work with the Thermal Dynamics Circle Cutting Guide Kit, part number 7-3291.

No, the magnetic pivot requires a ferrous metal surface (like mild steel) to adhere. It will not stick to aluminum or non-magnetic stainless steel.

No, this item is only the Magnetic Pivot Kit. The Circle Cutting Guide Kit (7-3291) must be purchased separately.

The magnetic pivot assembly replaces the standard pin pivot on the 7-3291 guide bar, usually securing with a set screw or similar mechanism included in the kit.

Yes, the magnet is designed to provide sufficient holding force to keep the center point stationary while the torch is rotated around it.

While the pivot holds the center, beveling depends on the capabilities of the torch and the guide bar setup, but the pivot itself supports stable rotation for such operations.

Yes, this is a genuine Thermal Dynamics accessory, ensuring proper fit and durability with their plasma systems.
