PLASMA TORCH CONSUMABLE PARTS
During the cutting process, the parts on the end of the torch are slowly consumed. To prevent
premature consumption of some torch parts and to prevent damage to the torch itself, it is necessary
to replace the consumable parts in a timely manner. When the cutting arc seems to be weaker than
normal or sputters, inspect all torch consumables for wear and damage and replace as needed.

HINTS FOR INCREASING LIFE OF CONSUMABLES
1. Use clean, dry, oil-free compressed air only.
2. Establish and maintain a good electrical connection with the ground clamp to the material
being cut.
3. Establish and maintain a consistent distance of about 1/16 inch between the material
being cut and the torch nozzle.
4. Establish and maintain proper movement speed. The optimum torch movement speed
for maximum consumable life is that which results in the main shower of sparks trailing
approximately 5 degrees behind the main axis of the torch. Moving the torch too fast
and/or not cutting completely through the metal while continuing to move the torch will
result in shorter consumable life.
5. Hold cutting starts to a minimum. Starts wear on the nozzle and electrode more than
actual cutting.
