Overview

The Bernard® Clean Air E™ fume extraction MIG gun captures up to 95% of weld fumes right at the source, helping keep your shop cleaner while giving welders a clear view of the weld. It’s lighter than the original Clean Air™ gun and designed to reduce fatigue over long shifts, with a flexible, low-profile cover that protects against heat and abrasion. A vacuum flow control slide lets operators fine-tune extraction for the job, and it connects to vacuum systems from most major manufacturers.
