Consumable life
How often you need to change the consumables on your torch will depend on a number of factors:
 The thickness of the metal being cut.
 The average length of the cut.
 The air quality (presence of oil, moisture, or other contaminants).
 Whether you are piercing the metal or starting cuts from the edge.
 Proper torch-to-work distance when gouging.
 Proper pierce height.
 Whether you are cutting in “continuous pilot arc” mode or normal mode. Cutting with a continuous pilot arc causes
more consumable wear.
Under normal conditions, the nozzle will wear out first when hand cutting. As general rule, a set of consumables lasts
approximately 1 to 3 hours of actual “arc on” time for 105 – 125 A hand cutting. Cutting at lower amperages may yield
longer consumable life. You will find more information about proper cutting techniques in
Operation on page 25.
