4. Carefully inspect the regulators for
damaged threads, dirt, dust, grease,
oil or other flammable substances.
Remove any contaminants with a
clean cloth. All acetylene hose
connections use left-handed threads
while the oxygen connections are
right handed. Attach the regulators
to the cylinder valves and tighten
securely with a wrench (right hand
threads) (see Figure 2).
Use the regulator
ONLY with the
gas(es) and pressure for which it was
intended.
5. Attach hoses to regulators and
tighten securely (Red=acetylene,
Green=oxygen). Remember that all
acetylene hose connections are left-
hand threads (see Figure 3).
!
CAUTION
General Safety
(Cont.)
If horizontal stowage
is necessary, or an
acetylene cylinder is inadvertently left
lying in a horizontal position, it must be
placed in an upright position for a
minimum of two hours before it can be
used. Otherwise, acetone in which the
acetylene is dissolved will be drawn out
with the gas. By dissolving acetylene in
acetone, pressures above 15 PSIG are
safely attainable. If enough acetone is
removed, the cylinder may become
unstable and explode.
●
Never tamper with or attempt to
repair compressed gas cylinders or
valves. Leaking cylinders or cylinders
with leaking valves should be placed
outdoors, identified and returned to
supplier.
Never lift cylinders
off the ground by
their valves, caps or with chains or slings.

WARNING

DANGER
3
Model WT5000
Set-Up
Oxy-fuel welding,
heating and cutting
equipment should not be used without
proper training in safety precautions and
procedures by a qualified instructor.
Compliance with all federal, state and
local regulations is required.
Prior to using this equipment, read all
information in the Safety Guidelines.
Failure to do so may result in fire,
explosion, damage to equipment,
severe personal injury or substantial
property damage.
GAS CYLINDERS
Gas cylinders with standard CGA fittings
are provided with the WT5000 Torch Kit.
These
empty
bottles can be exchanged
at your local welding gas supplier for
full bottles. The 20 cu. ft. oxygen bottle
has a CGA-540 valve, and the 10 cu. ft.
acetylene bottle has a CGA-200 valve.
1. Secure gas cylinders in the tote in the
upright position to a stationary
support, wall, workbench, post, etc.
2. Inspect the cylinder valve for oil,
grease or damaged parts.
Do not use
cylinder if oil,
grease or damaged parts are found.
Inform gas supplier of this condition
immediately.
3. Momentarily open and close the
cylinder valve (‘valve cracking’) to
dislodge any contaminants in the
valve seat area. DO NOT discharge
flow of gas at any person or
flammable material (see Figure 1).
Do NOT stand
directly in front of
the cylinder valve outlet. Always
perform valve cracking in a well
ventilated area.
