Bernard Welding Equipment MIG gun neck grip and neck coupler improve operator comfort and access to hard-to-reach joints, the company says. High-temperature silicone rubber neck grip slides onto all Q-gun and S-gun necks to reduce fatigue and increase control as operators rest the neck on their hand or forearm while welding. Grip shields hand or forearm from the heat of the neck. Neck coupler joins two or more gun necks consecutively, allowing operators to avoid ordering a custom neck. Installed in less than three minutes, according to the company, necks provide additional joint access.
