WORKING LIFESPAN OF CONSUMABLES
The following factors affect the frequency with which consum-
ables need to be replaced:
• Thickness of the metal cut.
• Average cut length.
• Air quality (presence of oil, moisture, or other pollutants).
• Execution of piercing of the metal or cutting from the edge.
• Correct piercing depth.
• Cutting done using mesh or solid material cutting mode. Cut-
ting done in mesh mode give rise to more wear of consum-
ables.
Under normal conditions, the nozzle wears out before the oth-
er consumables during cutting operations.
CONSUMABLES FOR MANUAL CUTTING
Figure F shows the consumables used for the plasma torches
supplied, complete with the CEA order codes.
These torches use shielded consumables and so the point of
the torch can be dragged over the metal to be cut.
