Q2-45-12 - Bernard Q-Gun 45-Degree 12-Inch Replacement Neck

Bernard Q2-45-12 Gooseneck for Q-Gun Series

The Bernard Q2-45-12 Gooseneck is a premium replacement component designed specifically for the Bernard Q-Gun and S-Gun series of air-cooled MIG welding guns. Engineered to handle amperage ratings between 300 and 400 amps, this body tube is an essential part for maintaining the performance and longevity of your welding equipment in heavy industrial environments. The neck features a standard 45-degree bend, which is the most versatile angle for general fabrication, allowing welders to maintain a comfortable hand position while achieving proper torch angle on flat and horizontal fillets.

With a length of 12 inches, this gooseneck provides extended reach compared to standard short necks, making it ideal for welding around fixtures or reaching into deeper assemblies without compromising wire feedability. The construction of the Q2-45-12 emphasizes durability and thermal efficiency. It utilizes a large tapered connection at the back end where it mates with the gun handle. This design maximizes surface area contact, ensuring optimal electrical conductivity and efficient heat transfer away from the front end consumables. This results in a cooler running gun and more consistent arc characteristics over long welding shifts.

One of the standout features of the Bernard Q-Gun neck system is its compatibility with jump liners. Instead of replacing the entire gun liner when the neck portion wears out or becomes clogged, the Q2-45-12 allows for the use of a short jump liner that resides only within the neck. This significantly reduces maintenance costs and downtime, as the jump liner can be replaced in under a minute without opening the gun handle or removing the main liner. The neck is also armored with a heavy-duty aluminum jacket to withstand the rigors of the shop floor, resisting impact and spatter buildup.

Key Industrial Benefits:

• High Conductivity: Tapered connection reduces electrical resistance and heat buildup.


• Maintenance Efficiency: Designed for use with quick-change jump liners.


• Durability: Armored construction protects internal components from impact.


• Versatility: 12-inch reach and 45-degree angle suit a wide range of applications.
