43049005 - Arcair SLICE 1/4 x 44 Uncoated Exothermic Rods (25-Pack)

Technical Overview of Arcair SLICE Uncoated Rods

The Arcair SLICE Exothermic Cutting Rod (SKU: 43049005) is a specialized industrial consumable designed for the SLICE exothermic cutting system. Unlike the standard flux-coated variants, this product is designated as "Uncoated" or "Plain," featuring a bare steel tube construction containing a patented arrangement of dissimilar metal wires. This internal configuration is critical for maintaining the exothermic reaction, which relies on the rapid oxidation of the ferrous material in a stream of high-purity oxygen. The reaction generates temperatures sufficient to liquefy or vaporize virtually any material, including ferrous and non-ferrous metals, as well as refractory materials like concrete and carbon.

This specific SKU offers a 1/4-inch diameter paired with an extended 44-inch length. The increased length serves multiple technical functions: it prolongs the burn time per rod, reducing changeover frequency during extensive cutting operations, and it provides significant reach for piercing deep holes or accessing recessed components. The absence of an external flux coating modifies the rod's handling characteristics and kerf profile, making it suitable for applications where flux residue is undesirable or where the rod must pass through tight clearances that a coated rod could not accommodate.

Ignition of the rod is typically achieved via a 12-volt battery spark or a mechanical striker. Once the tip reaches ignition temperature and the oxygen lever is depressed, the rod consumes itself without the need for continuous electrical current. This self-sustaining reaction makes the SLICE system uniquely capable in field environments where high-amperage power sources are unavailable. The 43049005 rods are manufactured to strict tolerances to ensure a consistent burn rate, preventing the "flame out" issues often associated with inferior exothermic consumables.
