Shroud Nozzle MB15 Mig Welding

The MB15 Shroud Nozzle is a high-performance, essential consumable engineered for the South African automotive, DIY, and light-industrial sectors. Designed specifically for the Binzel-style MB15 (15AK) air-cooled torch, it is the primary choice for operators welding at lower amperages (up to 180A). This nozzle is critical for directing a stable, concentrated flow of shielding gas over the weld pool, ensuring clean, porosity-free welds on thin-gauge mild steel, stainless steel, and security tubing.

Key Performance Features

• High-Conductivity Copper Alloy: Manufactured from premium copper to provide excellent heat dissipation and a high melting point, preventing the shroud from warping during extended welding runs.
• Tapered Conical Profile: Features a precision-tapered internal design that accelerates gas flow and provides a focused "shielding blanket," ideal for welding in tight corners and restricted spaces.
• Secure "Internal-Spring" Fit: Equipped with a high-tension internal spring that ensures a firm, concentric seat over the MB15 gas diffuser, keeping the contact tip perfectly centered.
• Polished Spatter-Resistant Surface: The smooth exterior finish is designed to reduce the adhesion of molten metal droplets, making post-weld cleanup faster and extending the life of the shroud.

Ideal Applications

• Security Gate & Burglar Bar Fabrication: The industry standard for welding 1.6mm to 2.5mm square tubing and palisade fencing where a clean finish is essential.
• Automotive Body & Exhaust Repair: Perfect for the low-amperage precision shielding required for thin-gauge car panels, silencer boxes, and custom exhaust manifolds.
• Light Agricultural Maintenance: A reliable choice for repairing farm gates, light-duty trailers, and irrigation stands in the workshop or field.
• DIY & Metal Art Projects: Ideal for home workshop users who require a versatile and affordable shielding solution for general steel fabrication.

Product Benefits

• Superior Weld Aesthetics: By maintaining a laminar gas flow, this nozzle significantly reduces oxidation and spatter, resulting in a "bright" and professional weld bead.
• Optimized Torch Balance: The lightweight design of the MB15 shroud ensures the torch remains easy to maneuver, reducing hand fatigue during intricate fabrication tasks.
• Simple "Push-Fit" Installation: Features a user-friendly design that allows for quick removal and cleaning with MIG Pliers without the need for specialized tools.

Pro Tip: To prevent the MB15 shroud from "sticking" to the gas diffuser, always apply a thin layer of MIG Anti-Spatter Gel to the internal threads and contact surfaces. If you notice "pinhole" porosity in your weld, check the inside of the shroud for spatter buildup; a clogged nozzle creates gas turbulence, which is the leading cause of contaminated welds.
