Description

Our custom Panasonic-style 500A brass swan neck represents the ultimate upgrade and replacement part for all genuine and compatible Panasonic 350A–550A MIG welding torches. Unlike standard copper necks that deform or crack under continuous high-current and mechanical stress, this swan neck is precision-machined from high-density, chrome-plated brass alloy that combines exceptional electrical conductivity with dramatically increased strength, rigidity, and resistance to bending fatigue.

Every bend radius and angle is manufactured to micron-level accuracy using CNC forming technology, ensuring perfect coaxial alignment of the power cable, gas hose, and wire liner. This eliminates wire feed issues, prevents bird-nesting, and delivers an ultra-stable arc even when running at full 500–550A duty cycles with 1.6 mm wire in spray or pulsed transfer modes.

The thick chrome plating provides a hard, smooth, low-friction surface that repels spatter, resists oxidation, and keeps the neck looking and performing like new for thousands of welding hours. Reinforced mounting flanges and threaded sections guarantee rock-solid attachment to the torch body and diffuser, while the robust construction shrugs off the inevitable knocks and impacts common in heavy industrial and robotic environments.

Whether you are replacing a worn neck on a manual Panasonic 500A gun or building high-uptime robotic welding cells that demand absolute repeatability and minimum downtime, this brass swan neck delivers unmatched longevity, superior heat dissipation, and consistent top-tier weld quality day after day.

Fully interchangeable with original Panasonic part numbers and third-party 500A systems. Available in standard 45° and optional custom angles upon request.
