Red Seal Welding Practice Exam

When shape cutting with PAC, the torch angle should be perpendicular to the plate. This is because perpendicular is the only correct angle for evenly cutting through the material without leaving any jagged edges. 45 degrees and 30 degrees would both result in uneven cutting and parallel would result in no cutting at all. Therefore, it is important to make sure the torch angle is perpendicular in order to achieve clean and precise cuts.
