Victor Style W-7 Welding Nozzle for 300 Series Handles

Victor Style W-7 Oxy-Acetylene Welding Nozzle | Size 7

Optimize your heavy welding and brazing operations with the Victor Style W-7 Welding Tip. Engineered for professional welders, this nozzle is designed to fit Victor 300 Series torch handles, providing a seamless integration into your existing oxy-fuel setup. The W-7 is a large-orifice tip, specifically sized for working with substantial material thicknesses, making it indispensable for heavy industrial fabrication, pipe welding, and extensive repair work.

Technical Performance: The W-7 tip features a swaged copper tube design that ensures smooth gas flow and optimal flame characteristics. It is rated for welding mild steel thicknesses between 1/2" (12.7mm) and 3/4" (19mm). The tip requires an oxygen pressure range of approximately 25-35 PSIG and an acetylene pressure range of 10-15 PSIG for optimal stability. Its long cone flame profile allows for deep penetration and excellent puddle control, which is critical when joining thick sections or performing build-up work.

Construction & Compatibility: Manufactured to strict tolerances, the tip includes dual silicone O-rings to prevent gas back-flow and leaks at the mixer connection. The copper alloy body offers superior thermal conductivity, keeping the tip cooler and reducing the risk of flashbacks compared to inferior materials. This nozzle is strictly for use with Oxygen and Acetylene fuel gas and is not recommended for alternate fuels like Propane or Propylene due to flame velocity differences. Equip your torch with this high-performance replacement part to ensure consistent weld quality and operational safety.
