43049009 - Arcair Slice Uncoated Exothermic Cutting Rods 3/8x36 (25-Pack)

Industrial Grade Exothermic Cutting Performance

The Arcair 43049009 Slice Uncoated Cutting Rods represent the pinnacle of exothermic cutting technology for industrial maintenance, demolition, and rescue operations. Designed to function with the Arcair Slice system, these rods utilize a patented single-piece construction that ensures a consistent and controlled burn. Unlike standard welding electrodes that require a continuous electrical arc, the Slice exothermic rod only requires an initial ignition source (such as a 12-volt battery or welding striker) and a continuous supply of oxygen. Once ignited, the rod consumes itself in a fierce exothermic reaction, generating temperatures in excess of 10,000°F.

This specific SKU features the "Plain" or uncoated configuration. While flux-coated variants are available for specific arc-stability requirements or underwater use, the uncoated 3/8" x 36" rod is the preferred choice for general-purpose, cost-effective cutting in open-air environments. The lack of coating reduces the overall diameter slightly, allowing for insertion into tighter spaces if necessary, while still delivering the massive thermal energy required to sever materials that defy conventional oxy-fuel or plasma processes. This includes mild steel, stainless steel, aluminum, cast iron, and significantly, non-conductive materials such as concrete, brick, and slag.

For MRO professionals, the utility of the Arcair Slice system lies in its versatility. Whether removing seized track pins on heavy mining equipment, cutting through bridge decking that contains both steel and concrete, or piercing holes for demolition charges, these rods perform reliably. The 36-inch length offers a significant safety advantage, keeping the operator at a greater distance from the molten spray and allowing for deep piercing applications without the torch handle entering the cut zone. Sold in packages of 25, these rods are an essential inventory item for heavy fabrication shops, scrap yards, and emergency repair teams.
