(Re)Introducing the Bernard® S-Gun™ Semi-Automatic Air-Cooled MIG Gun

The Bernard® S-Gun™ is back—with refreshed configurations and enhanced flexibility—making it better suited than ever for demanding, hard-to-feed welding applications. While our steel monocoil cable isn’t new, its thoughtful updates make a noticeable difference in performance and reliability.


Why Choose the S-Gun? It Starts with the Cable

This makes the S-Gun ideal for applications that require longer cable lengths frequently looped or routed around tight corners. The result? Fewer pinch-related issues and a smoother welding experience.
