998799 - ESAB #100 Oxy-Acetylene Multi-Flame Heating Nozzle

High-Performance Thermal Output for Industrial Fabrication

The ESAB Rosebud Oxy-Acetylene Heating Tip Assembly #100 is a specialized consumable designed for industrial environments requiring substantial thermal energy transfer. In the realm of heavy fabrication, structural steel erection, and equipment repair, the ability to rapidly raise the temperature of a workpiece is critical. This 'Rosebud' style tip utilizes a multi-flame orifice configuration that distributes heat over a wider surface area than standard cutting or welding tips, allowing for uniform heat soaking of the base material. This is particularly essential for preheating high-carbon steels to prevent cracking during welding, or for achieving the plasticity required to bend and straighten heavy metal sections.

Engineered specifically for Oxy-Acetylene gas mixtures, this tip takes advantage of acetylene's high flame temperature and heat release rate. The #100 size designation indicates a high-capacity flow potential, suitable for working on thick plates, large diameter pipes, and heavy castings. The internal geometry of the tip is precision-machined to ensure stable gas mixing and laminar flow, reducing the risk of turbulence that can lead to flame instability. The assembly is constructed from high-grade copper and brass alloys, selected for their superior thermal conductivity and resistance to deformation under the intense reflected heat generated during operation.

Operators utilizing the ESAB #100 Rosebud must ensure their gas supply system is capable of sustaining the necessary withdrawal rates. Due to the large volume of gas consumed by a tip of this size, manifolding cylinders or utilizing larger supply vessels is often required to prevent acetone withdrawal from acetylene cylinders. When properly configured, this heating assembly becomes an indispensable tool for thermal forming, stress relieving, and preparation of metal surfaces, offering reliability and efficiency synonymous with the ESAB brand.
