Consumables
01
Shield Cap
Inspect the shield cap to ensure all of the holes are clean and not plugged. If the shield cap
cannot vent gas properly it will result in uneven or imprecise cuts. The shield cap will only need
to be replaced if there is evidence of physical damage and/or if hole is out of round. If there is
spatter on the Shield it may still be usable. However, it may also be an indication that the Torch
is set too close to the material, especially in regard to materials thinner than .25 in. Typically
the shield cap will last up to 15-times as long as the electrode and nozzle.
Signs that Consumables Need Replacing
Signs of a Bad Electrode
• Torch not cutting at required speed
• Green discoloration of the arc
• Excessive dross
•
Signs of a Bad Nozzle
• Kerf too wide
• Operator needs to slow the Torch down because the Torch is not cutting well at desired
speed
• Oblong holes
Do not judge consumables by their color. Staining or discoloration do not necessarily
indicate worn consumables.
Make sure the opening
is not out of round.
Check that the holes are
clean.
