Manual 0-2601 3-7 INSTALLATION PROCEDURES
A. Using Shop Air
An inline pneumatic dryer/evaporator type air filter, capable of
filtering particulates to at least 5 microns with a dew point of
35°F (1.7°C), is required when using air from a compressor. This
type filter will insure that moisture, oil, dirt, chips, rust particles,
and other contminants from the supply hose do not enter the
torch. For highly automated applications, a refrigerated drier
plus a particulate filter may be used to chill the air to remove all
moisture.
CAUTION
Excessive oil or moisture in compressed air will
reduce torch parts life and cutting performance and
may cause torch failure.
The optional Two Stage Air Line Filter is shipped with
the following components:
