How should the torch be moved during cutting for effective results?

To achieve effective results during plasma arc cutting, the torch should be moved smoothly without side-to-side movement. This technique allows for consistent cutting speed and helps maintain a steady arc between the torch and the workpiece. A smooth motion ensures that the plasma jet can penetrate the material evenly, which is crucial for achieving good cut quality and minimizing dross or slag formation.

When the torch is moved jerky or too quickly, it can disrupt the stability of the arc, leading to inconsistent cutting and potential defects in the cut line. On the other hand, overly erratic movements can cause overheating in certain spots and make it difficult to maintain control over the cut. Thus, maintaining a smooth and controlled motion is vital for producing clean, accurate cuts and ensuring the longevity of the consumables.
