42049003 - Arcair Slice Exothermic Cutting Rods 1/4" x 22" Flux Coated (100 Pack)

Arcair 42-049-003 Slice Exothermic Cutting Rods

When the job demands cutting power beyond the capabilities of standard welding equipment, the Arcair Slice Exothermic Cutting Rods are the industry standard for versatility and performance. This 100-pack of 1/4" x 22" rods is designed for use with the Arcair Slice torch system. The core of the technology lies in the patented single-piece construction of the rod, which maintains the necessary chemical balance to sustain an exothermic reaction. Once the rod is ignited—typically using a 12-volt battery striker or a welding power source—the flow of oxygen through the center of the rod causes the steel rod itself to burn. This reaction requires no continuous electrical power, making the system highly portable and effective in remote locations.

These specific rods feature a flux coating, distinguishing them from bare rods. The flux coating is essential for applications where the rod might contact the sidewalls of a deep cut or pierce. It prevents the rod from shorting out electrically (during ignition) and helps contain the heat at the tip, improving the efficiency of the cut. The 1/4-inch diameter is the standard size for general-purpose exothermic cutting, offering a high oxygen flow rate for rapid material removal.

The Arcair Slice system is unique because it does not require the base material to be conductive or pre-heated. This allows welders and fabricators to cut through composite materials, slag, refractory brick, and heavily rusted or painted metals without preparation. For maintenance and repair operations (MRO), this means significantly reduced downtime when dealing with stubborn, fused, or damaged components. The 22-inch length ensures operator safety by keeping hands at a distance from the intense heat and spatter generated during the piercing process.

Performance Features

• Universal Cutting: Cuts ferrous and non-ferrous metals, as well as masonry and composites.
• Self-Sustaining: Requires oxygen and ignition only; no continuous welding current needed.
• Flux Coated Design: Enhances arc control and prevents side-arcing in tight spots.
• High Temperature: Generates heat up to 10,000°F for rapid piercing.
