Matweld Welding Nozzle Swagged Pack of 3

The Matweld Swaged Welding Nozzle is a precision-engineered tip for use with oxy-acetylene welding torches. Unlike the "detachable" tip system, swaged nozzles are manufactured as a single, tapered copper unit. This design ensures a perfectly laminar gas flow and superior heat dissipation, making them the industry standard for high-quality gas fusion welding and brazing.

Technical Specifications

• Product Code: MAT3250P (Pack of 3).
• Material: High-grade Tellurium Copper (for heat resistance and durability).
• Type: Swaged (One-piece construction).
• Gas Compatibility: Oxy-Acetylene.
• Torch Compatibility: Fits standard Matweld, Safegas, and Afrox-style (Type 2/3) welding mixers.
• Sizes: Typically available in sizes 1, 2, 3, 5, 7, 10, and 13. (Check the specific pack for the number stamped on the side).

Key Features

• Improved Heat Dissipation: The solid copper construction pulls heat away from the tip more efficiently than multi-piece nozzles, significantly reducing the risk of "backfire" or "flashback" during heavy use.
• Laminar Gas Flow: The "swaged" (tapered) internal profile ensures the oxygen and acetylene mix flows smoothly, resulting in a very stable, needle-sharp neutral flame.
• Durable Orifice: The exit hole is precision-drilled to maintain its shape over time, resisting the buildup of carbon and slag.
• Tapered Profile: The slim, pointed design provides the operator with an excellent view of the weld pool, which is critical for intricate pipe work or fine sheet metal repairs.
• Pack Value: Buying the 3-pack ensures you have replacements on hand, which is vital since a dropped or clogged nozzle can stall a project.

Usage & Maintenance Tips

• Cleaning: Never use a drill bit or a piece of wire to clean the nozzle orifice. Use a dedicated Matweld Tip Cleaner (a set of fine, serrated wires) to gently remove soot without enlarging the hole.
• Hand Tighten Only: Screw the nozzle into the mixer hand-tight. Overtightening with a wrench can damage the soft copper threads or the seating surface, leading to gas leaks.
• Check for Soot: If your flame becomes "forked" or unstable, there is likely a small piece of carbon in the tip. Stop immediately and clean the nozzle to prevent a backfire.
• Sealing Surface: Periodically inspect the mating surface where the nozzle meets the mixer. If it is scratched or dented, it may leak gas, which can ignite and cause a fire at the torch handle.
• Anti-Spatter: While less common in gas welding than MIG, a light wipe of the tip with a dry cloth helps prevent molten metal from sticking during overhead work.
