What is a consequence of using an incorrect or excessively high amperage during cutting?

Using an incorrect or excessively high amperage during plasma cutting significantly affects the cutting process, leading to severe torch damage and poor-quality cuts. When the amperage is set too high, it increases the amount of heat generated by the plasma arc. This can cause several issues, such as excessive melting of the material being cut, leading to rough edges, excessive dross (metal slag that hardens on the cut), and distortion of the workpiece.

Moreover, high amperage can also damage the torch components, including the electrode and nozzle, which are designed to handle specific current levels. Over time, this can lead to premature wear and failure of these components, necessitating costly repairs or replacements. In contrast, using the correct amperage settings is crucial for achieving clean, precise cuts and maximizing the lifespan of the cutting equipment. This understanding underscores the importance of calibrating the cutting parameters appropriately to avoid detrimental consequences.
