08Z89 - Oxweld 1515-12 Acetylene Heating Nozzle

Heavy-Duty Heating with the Oxweld 1515-12

The ESAB Oxweld 1515-12 Heating Nozzle (08Z89) is a premier choice for industrial professionals requiring intense, localized heat for metalworking applications. Designed to operate with oxy-acetylene systems, this multi-flame nozzle—often referred to as a "rosebud"—delivers a high volume of heat output necessary for manipulating heavy steel sections. Whether you are bending structural beams, straightening warped plates, or preheating materials for welding, the 1515-12 provides the thermal efficiency needed to reduce soak times and improve productivity.

Constructed from high-quality copper, the 1515 series nozzles are engineered to withstand the rigors of daily industrial use. The copper material not only provides structural integrity but also acts as an excellent thermal conductor, helping to dissipate reflected heat and keep the tip cool during prolonged operation. This specific model, the Size 12, offers a substantial flame footprint, making it suitable for medium-to-heavy duty applications where smaller tips would fail to bring the base metal to temperature quickly enough.

Precision and Safety

Safety and performance go hand-in-hand with Oxweld equipment. The 1515-12 features precision-drilled ports that ensure a stable, symmetrical flame cone. This stability is crucial for achieving even heating across the workpiece, preventing hot spots that could damage the metallurgy of the steel. When paired with the correct Oxweld torch handle and mixer, this nozzle resists flashback and backfire, common issues in high-output heating scenarios. It is essential to ensure your acetylene supply is sufficient to support the withdrawal rate required by a Size 12 tip to maintain safe operation.

Applications

• Flame Straightening: Correcting distortion in welded structures by applying localized heat patterns.
• Bending and Forming: Heating pipe, bar, or plate to make them pliable for shaping.
• Preheating: Raising the temperature of thick materials prior to welding to prevent cracking.
• Shrinking: Using heat to shrink-fit parts or correct dimensional errors.

Trust Josef Gas to supply genuine ESAB Oxweld components that keep your fabrication shop running smoothly. The 08Z89 nozzle is a testament to the reliability and performance that welders have expected from the Oxweld brand for decades.
