The consumables’ life is shortened. Causes can be:
• The arc current, arc voltage, travel speed, and other variables are not set as specified in the
cut charts.
• Firing the arc in the air (beginning or ending the cut off of the plate surface). Starting at the
edge is acceptable as long as the arc makes contact with the workpiece when started.
• Starting a pierce with an incorrect torch height. For the Powermax45, the pierce height is
generally 2.5 times the cutting height. Refer to the cut charts for specifics.
