When piercing very thin metal, how should the torch be positioned?

Positioning the torch directly over the piercing point at a 0-degree work angle is the most effective technique when piercing very thin metal. This approach ensures that the arc is concentrated directly at the point of initiation, allowing for more precise control over the cutting process. With the torch at a 0-degree angle, the maximum energy from the plasma arc can be effectively delivered to the thin material, resulting in a clean cut and minimizing the risk of distortion or warping. This positioning is particularly important when working with thin materials, where any deviation in angle could lead to uneven cutting or potential melting of the surrounding metal.
