Workpiece Preparation and Backing. For thin metal, a flow rate between 10 and 15 cubic feet per hour (CFH) is usually sufficient to shield the puddle without disrupting it.
Hesitation is the enemy of thin metal welding; holding the torch in one place for more than a fraction of a second will almost certainly result in a hole. Mastering mig welding thin metal settings is the single most critical skill for any fabricator working with gauge steel, sheet metal, or automotive panels.
