A pure CO2 mixture, common for thicker steel, is generally too aggressive and will cause spatter and instability on thin gauge metal. Workpiece Preparation and Backing.
Optimizing Gas Flow for Thin Metal MIG Welding
Matching Wire Diameter to Task Selecting the correct wire diameter is non-negotiable when working with thin metal settings. This allows you to run higher wire feed speeds without the risk of blowing holes in the material, resulting in smoother beads and significantly reduced distortion.
The goal is to move swiftly and confidently, dragging the bead slightly behind the gun. 035-inch wire is standard for general purpose fabrication, it often delivers too much current for delicate work.
Optimizing Gas Flow for Thin Metal Mig Welding
023-inch or even 0. 018-inch wire is highly recommended.
