3.06 Gas Connection
A. Connection
Connect the gas , compressed air or nitrogen (N2)
only, to the Power Supply as described in the Manual
supplied with the Power Supply.
CAUTION
Air supply must be free of oil, moisture, and other
contaminants. Excessive oil and moisture may
cause double-arcing, rapid tip wear, or even com-
plete torch failure. Contaminants may cause poor
cutting performance and rapid electrode wear.
B. Checking Air Quality
To test the quality of air, place a welding filter lens in
front of the torch and turn on the gas. Any oil or
moisture in the air will be visible on the lens. Do not
initiate an arc!
C. Filtering
An in-line pneumatic dryer/evaporator type air fil-
ter, capable of filtering to at least 5 microns, is required
when using air from a compressor. This type filter
will insure that moisture, oil, dirt, chips, rust particles,
and other contaminants from the supply hose do not
enter the torch. For highly automated applications,
a refrigerated drier may be used.
