405-45 - Bernard 405-45 Q-Gun Neck, 45 Degree, 400 Amp

Genuine Bernard 405-45 45-Degree Neck for 400A MIG Guns

The Bernard 405-45 Neck is a premium replacement component designed specifically for Bernard Q-Gun, S-Gun, and the modular BTB (Best of the Best) MIG gun series. Engineered to handle the rigors of heavy industrial welding, this neck is rated for 400 Amps, making it an ideal choice for high-amperage fabrication, structural steel work, and heavy equipment manufacturing. The 45-degree bend angle is the industry standard for general-purpose welding, offering a perfect balance between reach and ergonomic comfort for the operator.

One of the standout features of the Bernard 405-45 is its rotatable design. Unlike fixed necks that force the welder into awkward positions to reach difficult joints, this neck can be rotated 360 degrees without the need for tools. This flexibility significantly reduces operator fatigue and improves weld quality by allowing the welder to maintain a proper gun angle in various positions. The neck is constructed with robust materials, including heavy-duty aluminum armor, which protects the internal components from impact, spatter, and extreme heat.

Proper gas flow and wire feeding are critical for producing sound welds, and the 405-45 excels in both areas. Its internal geometry is precision-engineered to minimize wire drag and ensure a laminar flow of shielding gas, reducing the risk of porosity. Whether you are replacing a damaged neck or reconfiguring your MIG gun for a specific task, the Bernard 405-45 delivers the reliability and performance professional welders demand. Trust in genuine Bernard parts to maintain the integrity and longevity of your welding equipment.
