Overview

Built for production environments where the heat never lets up, the Bernard® T-Gun™ semi-automatic water-cooled MIG gun delivers a 100% duty cycle with CO₂ and 60% with mixed gases. Water cooling runs internally all the way to the diffuser, and nozzles thread directly onto the neck for a cooler-running front end, keeping you welding longer with less wear on consumables.
