2 "Time-Delay" fuses are UL class "RK5" .
3 "Normal Operating" (general purpose – no intentional delay) fuses are UL class "K5" (up to and including 60 amp), and UL class "H" ( 65 amp and
above).

For any single or three phase voltage from 208 V to 575 V, the Amperes Input at
Rated Load Output is the same for 50 Hertz or 60 Hertz input power. For example,
the amperes input for 230 V, 50 Hz, single-phase input power is 33 amperes. The
amperes input for 230 V, 60 Hz, single-phase input power is also 33 amperes.

1 Work Clamp
2 Workpiece
Connect work clamp to a clean,
paint-free location on workpiece, as
close to cutting area as possible.
.
Use only clean, dry air with 90
to 150 psi (620 to 1035 kPa)
pressure.
3 Gas/Air Inlet Opening
4 Hose
.
Hose must have a minimum
inside diameter of 3/8 in
(9.5 mm).
5 Teflon Tape
Obtain hose with 1/4 NPT right-
hand thread fitting. Wrap threads
with teflon tape (optional) or apply
pipe sealant, and install fitting in
opening. Route hose to gas/air
supply.
Adjust gas/air pressure according
to Section 3-2.
