0469335880 - ESAB PSF 500 Straight MIG Gun Neck Assembly

Genuine ESAB Straight Swan Neck for PSF 500

The ESAB Swan Neck Straight (0469335880) is a specialized replacement component designed exclusively for the renowned PSF 500 series of gas-cooled MIG welding torches. While the majority of manual MIG welding applications utilize a curved swan neck (typically 45 or 60 degrees) to reduce wrist strain and improve visibility, there are specific industrial scenarios where a straight neck is indispensable. This OEM part converts your standard PSF 500 into a tool capable of reaching into deep cavities, welding inside pipes, or functioning within semi-automated fixtures where a linear approach is required.

Constructed to ESAB's rigorous standards, this swan neck is built to handle the high thermal loads associated with 500-amp welding procedures. The PSF 500 is a workhorse in the heavy fabrication industry, known for its reliability in structural steel, shipbuilding, and heavy machinery repair. This replacement neck maintains that legacy by ensuring efficient current transfer from the cable assembly to the contact tip. Poorly manufactured aftermarket necks can suffer from voltage drops or overheating, but this genuine ESAB component guarantees stable arc performance and consistent shielding gas coverage.

The internal geometry of the neck is precision-engineered to minimize wire feeding friction. In straight-neck configurations, wire feeding is often naturally smoother due to the lack of bends, but the quality of the liner seating and the concentricity of the bore remain critical. This part ensures that the wire liner seats correctly, preventing gas leaks and ensuring that the shielding gas flows laminarly over the weld pool. Whether you are replacing a damaged unit or reconfiguring your torch for a specific job, this straight swan neck offers the fit, finish, and performance professional welders demand.

Installation is straightforward, designed to mate perfectly with the PSF 500 handle assembly. It utilizes the standard connection points, ensuring a secure mechanical and electrical bond. By using genuine ESAB parts, operators protect the longevity of their equipment and ensure safety compliance in demanding industrial environments.
