6. PlacetheMODEswitchtotheRUNposition.
7. Set the Plasma Power Supply Enable / Disableswitch (on the Gas Control Module) to Enable. The Module
performspurgesof15seconds,11seconds,andanother11seconds.Thisremoveswaterfromthetorch
parts.
NOTE
When switching gases between operations, allow enough purge time to clear the prior gas from the torch leads.
CAUTION
While nothing prevents the operator from switching gases during piloting or cuing it is not recommended to do
so. If the operator switches gases during piloting or cuing, the power supply will nish the cut with the rst gas
chosen. Then the gas control will switch to the new gas. Switching gases during piloting or cuing may damage
torch parts, torch leads, the control module, or the piece being cut.

Cut Surface
The condition (smooth or rough) of the face of the cut.
Bevel Angle
The angle between the surface of the cut edge and a plane perpendicular to the surface of the plate. A perfectly
perpendicularcutwouldresultina0°bevelangle.
Top-Edge Rounding
Rounding on the top edge of a cut due to wearing from the initial contact of the plasma arc on the workpiece.

Nitride Build-up
Nitride deposits which may remain on the cut edge of the carbon steel when nitrogen is present in the plasma
