Using a gas lens to your advantage
Many people ask…why or when should I use a gas lens? The main reason is to allow you to flood the area you are welding with the best possible gas coverage to ensure you are reducing the possibility of oxygen contamination. Another great use of the gas lens is reaching difficult areas that need to be welded. A good example of this is a tight cluster of tubing that you may encounter on many of today’s sport utility and race vehicles. By this, I mean that it allows you to stick out the tungsten much farther while still maintaining gas coverage to access these hard-to-reach areas (see photos).
