These INSTRUCTIONS are for experienced operators. If you are not fully familiar with the principles of operation
and safe practices for oxy-fuel gas equipment, we urge you to read our booklet "Precautions and Safe Prac-
tices for Gas Welding, Cutting and Heating," Form 2035. The same information appears in the "Oxy-Acetylene
Handbook" which may be purchased from any ESAB Distributor. Do NOT permit untrained persons to install,
operate, or maintain this equipment. DO NOT attempt to install or operate this equipment until you have read
and fully understand these instructions. If you do not fully understand these instructions, contact your supplier
for further information.
The cutting torches covered by these instructions are listed by third parties only when using parts manufac-
tured by ESAB Welding & Cutting Products to the specifications on file with third party listed, and when they
are used in the gas service for which they are designed and listed. The use of other parts that cause damage
or failure to the equipment will void the manufacturer's warranty.
OPERATING INSTRUCTIONS
WARNING
SCT-4200 Series cutting torches can be used with
any fuel gas including acetylene.
Be sure gas flow is sufficient for nozzle size.
Adjust regulators for proper psig pressures.
Adjust throttle valves properly.
Keep torch in good repair.
DO NOT throttle back gases to use large nozzle on
thin material.
CONNECTING
1. Attach regulator to the oxygen cylinder or station
valve; attach fuel gas regulator to cylinder or station
valve unless fuel gas is to be supplied through a
hydraulic or check valve from a pipeline at desired
pressure.
2. Attach oxygen hose to the oxygen regulator; at-
tach fuel gas hose to the fuel gas station valve or
regulator. Attach both hoses to torch. Tighten all
connections nuts with a wrench.
Be sure this information reaches the operator.
You can get extra copies through your supplier.
F.G.—CGA-023 (9/16"—18LH)
CAUTION
3. Attach nozzle to torch head, and tighten connection
nut with a wrench.
4. Check throttle valve packing nuts for tightness.
ADJUSTING GAS PRESSURES
Fuel Gas: If fuel gas is supplied from a station outlet
without a regulator, merely open the station valve. If
fuel gas is being supplied through a station or cylinder
regulator, open the fuel gas valve on the torch, turn in
the pressure-adjusting screw on the regulator until the
regulator deliver-pressure gauge indicates the desired
pressure (see chart under "Operating Data"). Then im-
mediately close the fuel gas valve.
Oxygen: Open the cutting oxygen valve by depressing
its valve lever fully. Turn in the pressure-adjusting screw
until the regulator delivery-pressure gauge registers the
desired pressure (see chart under "Operating Data").
Then release the cutting oxygen lever.
NOTE: When gaugeless regulators are used, do not
open torch valves. Merely turn in the pressure-
adjusting screws to the desired pressures as
indicated on the scales of the regulator caps.
