3-5. Connecting Work Clamp And Gas/Air Supply
Ref. 803 640-A / 802 201-B
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 supply
with 90 to 150 psi pressure.
Torch requires 80 psi pressure.
3 Gas/Air Inlet Opening
4 Hose
Use hose with an inside diameter of
at least 3/8 in. If hose is over 40 ft
(12.2 m) in length, use hose with 1/2
in inside diameter.
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

1 Choose a circuit breaker with time-current curves comparable to a Time Delay Fuse.
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).
