7-3291 - Thermal Dynamics 1Torch Circle Cutting Attachment Kit

Precision Plasma Cutting Made Simple

Unlock the full potential of your Thermal Dynamics plasma cutting system with the Thermal Dynamics 7-3291 Circle Cutting Guide Kit. Designed for professional fabricators and metalworkers who demand accuracy, this accessory kit transforms your handheld torch into a precision instrument capable of cutting perfect circles every time. Whether you are fabricating flanges, cutting access holes in ductwork, or creating artistic metal pieces, this guide eliminates the inconsistencies of freehand cutting.

The 7-3291 kit is engineered for versatility and ease of use. It features an adjustable radius bar that allows operators to cut circles ranging from as small as 2.125 inches (54 mm) up to a substantial 27.75 inches (705 mm) in diameter. The setup is intuitive: simply attach the appropriate bushing to your torch cup, secure the radius bar, and set your pivot point. The kit includes a magnetic attachment base, which is ideal for ferrous metals, providing a rock-solid center point that won't slip during the cut. This stability is crucial for maintaining a consistent kerf width and achieving a clean edge that requires minimal secondary grinding.

Robust Industrial Design

Durability is a hallmark of Thermal Dynamics accessories. This circle guide is constructed with a high-quality insulating plastic body that prevents high-frequency (FH) current leakage, ensuring operator safety and protecting the equipment. The axles and wheel guards are manufactured from stainless steel, offering exceptional resistance to rust and corrosion even in harsh shop environments. The wheels themselves are designed to be non-jamming, gliding smoothly over plate surfaces, including those with minor imperfections or rust.

Broad Compatibility

One of the standout features of this kit is its wide compatibility. It is designed to fit the industry-standard 1Torch series, including the SL60 and SL100 torches found on Cutmaster 52, 82, 102, and 152 machines. Additionally, it supports a legacy range of PCH torches (PCH-10 through PCH-100XL), making it a valuable addition to older equipment as well. The rotating head design allows for a full 360-degree operation without the operator having to change position or wrestle with twisted torch leads, significantly improving workflow efficiency.
