For square edges to be cut properly, what angle should the torch be held at?

The torch should be held at a 90-degree angle to ensure that square edges are cut properly. This perpendicular angle creates a direct path for the plasma arc to cut straight down through the material. Holding the torch at 90 degrees minimizes the risk of angular distortion or tapering at the edges, which is crucial for achieving a clean and precise cut. A square edge cut is characterized by its flat vertical surfaces, and maintaining the torch at this angle allows for the best control and most uniform penetration of the plasma arc into the workpiece. This leads to optimal edge quality, essential for subsequent assembly or finishing processes.
