QT-F-6 - Bernard 6-Inch Flexible MIG Gun Neck Assembly

Product Overview

The Bernard QT-F-6 Neck is a premium flexible tube assembly designed to enhance the versatility and performance of Bernard MIG guns. Engineered specifically for the Q-Gun™ and S-Gun™ series, this component is an essential replacement part for industrial welding operations requiring adaptability and precision. The unit features a 6-inch flexible length, allowing welders to navigate complex geometries and access joints that are otherwise difficult to reach with standard rigid necks. This flexibility does not compromise the structural integrity of the gas flow or wire feeding path, ensuring consistent weld quality even in constrained positions.

Technical Engineering & Compatibility

Technically, the QT-F-6 integrates Bernard's proprietary Stay-Tite™ technology. This cone-style connection system is critical for maintaining high electrical conductivity between the gun and the neck. By maximizing surface contact, the Stay-Tite™ design effectively dissipates heat, thereby prolonging the lifespan of the consumable and the gun handle itself. The neck is rated for use with gun platforms ranging from 150 to 600 amps, making it a versatile stock item for facilities utilizing varied power outputs. The assembly is designed for tool-free rotation, allowing the neck to be oriented 360 degrees to suit the specific angle of the workpiece without requiring downtime for mechanical adjustments.

Maintenance and Serviceability

Maintenance efficiency is a core feature of the QT-F-6. The neck is engineered to be easily removable, which simplifies the process of changing jump liners—a common maintenance task in high-volume welding environments. While rigid necks in this series often feature polished aluminum armor, this flexible variant is constructed with specialized materials to allow bending while protecting the internal liner and power cable. It serves as a direct replacement for damaged or worn necks and is a critical upgrade for operators facing accessibility challenges in heavy fabrication, automotive, or structural steel applications.
