OVERVIEW

Heavy-Duty Industrial Welding Nozzle

The ESAB/Victor W-17 Size 12 Welding Head (SKU: 17270) is a premium consumable designed for heavy-duty industrial welding and heating applications. Engineered to integrate seamlessly with Victor 300 Series torch handles (such as the 315FC), this nozzle provides the thermal output required for working with thick steel plates and structural components. The W-17 series is renowned for its "long cone" flame characteristic, which allows for deep heat penetration and precise puddle control on substantial workpieces.

Manufactured from high-grade copper, the nozzle is designed to dissipate heat rapidly, preventing tip overheating during prolonged use. The internal geometry is precision-machined to ensure smooth gas flow and optimal mixing of oxygen and acetylene, resulting in a stable, neutral flame that is essential for high-quality welds. The Size 12 orifice is specifically calibrated for heavy material thicknesses, typically ranging from 1/2-inch to 3/4-inch steel, making it an indispensable tool for structural fabrication, shipyards, and heavy equipment repair.

Reliability is a core feature of the W-17 design. It utilizes a double O-ring sealing system to ensure a gas-tight fit within the torch handle or mixer, minimizing the risk of flashbacks and leaks. This nozzle is strictly for use with Oxy-Acetylene gas systems and should not be used with alternate fuel gases unless specified by the manufacturer. Whether used for fusion welding or localized pre-heating, the W-17 #12 delivers consistent performance in demanding environments.

FAQ

The W-17 #12 is designed for use with Victor 300 Series torch handles, such as the 315FC.

A size 12 welding tip is generally suitable for welding steel thicknesses between 1/2 inch and 3/4 inch.

No, the W-17 series is designed specifically for Oxy-Acetylene gas service. Using other fuel gases requires different tip designs (like UN or TEN series).

The W-17 nozzle typically interfaces with the torch handle's mixing system. Ensure your 300 series handle is equipped with the correct mixer assembly if it is not integral.

No, this is a welding and heating nozzle. For cutting, you would need a cutting attachment and cutting tips (like the 1-101 series).

Use a standard tip cleaner set. Select the wire size that fits the orifice snugly without forcing it, and file gently to remove carbon buildup.

Popping usually indicates a starved tip (insufficient gas flow), a dirty tip, or overheating. Check your regulator settings for a size 12 tip and ensure the tip is clean.

A long cone flame provides better visibility and allows for deeper heat penetration into the joint, which is critical for welding thicker materials.
