OVERVIEW

Industrial Grade Flexible Gun Tube for Magnum PRO Systems

The Lincoln Electric KP3200-1 is a specialized Flexible Gun Tube Assembly designed for the Magnum PRO Curve series of MIG welding guns. Engineered to meet the rigorous demands of heavy industrial fabrication, this component is rated for 400 Amps, ensuring it can handle high-deposition welding processes without overheating or degradation. The assembly serves as the critical conductive path between the gun handle and the contact tip, delivering both welding current and shielding gas to the arc zone with precision and reliability.

One of the defining technical characteristics of the KP3200-1 is its flexible architecture. Unlike rigid gun tubes (goosenecks) that are fixed at specific angles (typically 45 or 60 degrees), this assembly features a specialized internal structure that allows the operator to bend the neck to custom angles. This capability is essential for applications involving complex geometries, pipe welding, or structural assemblies where standard torch access is restricted. Despite its flexibility, the tube maintains a consistent internal diameter to ensure smooth wire feeding and laminar gas flow, preventing porosity and wire chatter issues often associated with inferior flexible necks.

As part of the Magnum PRO ecosystem, this gun tube is fully compatible with Lincoln Electric's industry-leading Copper Plus contact tips and anti-seize diffusers. The integration with the Magnum PRO Curve handle ensures a secure mechanical and electrical connection, minimizing resistance and heat buildup at the junction point. Maintenance personnel and welding engineers will appreciate the durability of the outer insulation, which is resistant to radiant heat, spatter adhesion, and abrasion, significantly extending the service life of the component in harsh shop environments.

FAQ

The KP3200-1 is designed specifically for Lincoln Electric Magnum PRO Curve series MIG guns rated for 400 Amps.

It is recommended to adjust the bend of the tube before striking an arc. Adjusting while hot or during welding may damage the internal components or insulation.

The KP3200-1 is rated for 400 Amps. However, extreme bends can slightly restrict airflow or wire feeding, so it is best practice to use the minimum bend necessary for the job.

This tube assembly utilizes standard Magnum PRO consumables, including Copper Plus contact tips and Magnum PRO nozzles.

Yes, the KP3200-1 is a direct replacement for the standard rigid gun tube on Magnum PRO Curve 400A guns, offering the added benefit of flexibility.

While built for industrial use, flexible necks have moving internal parts. They are durable but generally have a shorter lifespan than rigid necks if bent frequently and aggressively. Treat it with care to maximize life.

No, the gun liner is typically part of the cable assembly or sold separately. This part is the gun tube assembly only.

No, this is designed for the 'Curve' handle series. Barrel style guns typically use different mounting geometries.
