SAFETY INSTRUCTIONS
EVERY TIME a machine cutting torch is used the
following safety and operation precautions MUST BE
PRACTICED! Deviation from the following safety and
operation instructions can result in fire, explosion,
damage to the apparatus or injury to the operator.
1. Inspect the inlet connections, valves, and torch
head for dirt, dust, oil, grease, or damaged parts.
Dirt or dust can be removed with a clean cloth.
DO NOT USE THE CUTTING TORCH IF OIL
OR GREASE IS PRESENT! Have your
manufacturer’s repair center clean the torch or
repair any damage.
2. Inspect the torch head. The tapered seating
surface must be in good condition. If dents, burrs
or burned seats are present, the seat must be
resurfaced. If the torch is used with poor setting
surface, backfire or backflash may occur and
damage the equipment.
3. Select the required size and type of cutting tip.
Inspect the tip seating surface for damage.
REMEMBER- these seating surfaces prevent
premature mixing of gases that can cause fire
and explosions. If the tapered seats on the tip
are damaged, DON’T USE IT! Inspect the preheat
and cutting oxygen holes. Spatter can stick on or
in these holes but can be removed with a tip
cleaner.
4. Insert the tip in the Cutting Torch head and tighten
securely.
5. Adjust the regulator delivery pressures according
to the size and type of tip being used.
6. IMPORTANT: Always purge out the cutting oxygen
passages by opening the cutting oxygen valve
(at least five seconds before lighting the torch.)
Open the fuel valve approximately one-half turn
and ignite the gas with a spark lighter. Adjust the
fuel valve until the flame clears the end of the tip
about ½ inch (13mm), then reduce slightly to
return the flame to the tip.
