Type 551 Welding Tip – Oxy/Acetylene

The Type 551 Welding Tip is a precision-engineered oxy-acetylene nozzle designed for welding, brazing, silver soldering and general metal fabrication applications. Manufactured to provide a stable, concentrated flame, Type 551 tips deliver excellent heat control and consistent performance across a wide range of workshop and industrial tasks.

Available in multiple sizes to suit different material thicknesses and heat requirements, these tips allow operators to select the appropriate flame intensity for both fusion welding and brazing operations, helping to improve productivity, weld quality and gas efficiency.

Suitable for use with compatible oxy-acetylene welding torches, Type 551 Welding Tips are commonly used in workshops, fabrication facilities, maintenance departments and educational training environments.

Key Features

  • Suitable for welding, brazing and silver soldering
  • Stable and controllable flame characteristics
  • Available in multiple sizes for varying material thicknesses
  • Suitable for mild steel fabrication, repair and maintenance work
  • Consistent gas flow for reliable welding and brazing performance
  • Durable construction for workshop and industrial use

Tip Selection Guide

Tip Size Metal Thickness (mm) Acetylene Pressure (kPa) Oxygen Pressure (kPa) Gas Consumption (L/min each gas)
8 2 mm 50 kPa 50 kPa 2 L/min
10 3 mm 50 kPa 50 kPa 3 L/min
12 3 – 4.5 mm 50 kPa 50 kPa 4 L/min
15 5 – 6.5 mm 50 kPa 50 kPa 6.5 L/min
20 8 – 10 mm 50 kPa 50 kPa 12 L/min

Note: The above information represents typical operating ranges only. Actual performance may vary depending on equipment condition, operator technique, tip condition, gas purity, regulator performance and material type.

Recommended Applications

  • Oxy-acetylene welding
  • Brazing and silver soldering
  • General steel fabrication
  • Maintenance and repair work
  • Automotive repair and restoration
  • HVACR fabrication and repair
  • Workshop and training environments

Understanding Tip Sizes

Selecting the correct welding tip is critical for achieving good weld quality and efficiency. Smaller tip sizes provide a concentrated flame for thinner materials, while larger tips deliver greater heat output for thicker sections. Using the appropriate tip size helps maintain weld quality, minimise distortion and optimise gas consumption.

Operator Guidance

For best results, set oxygen and acetylene pressures to the recommended values and adjust to a neutral oxy-acetylene flame before welding. Ensure flashback arrestors are fitted to both oxygen and acetylene lines and follow all relevant oxy-fuel safety procedures.

Always select the tip size best suited to the material thickness being welded to achieve optimum penetration, control and productivity.
