1. safety
9 Always have a fire extinguisher nearby.
9 never use oxygen or fuel gas to blow soot or dirt from your clothes.
8 do not wear ragged clothes, as sparks can ignite the ragged or loose ends.
9 Always wear goggles or a helmet with the appropriate shade lens.
8 do not use shaded safety spectacles or unshaded face shield visors for cutting or welding. they do not stop the harmful rays which
cause eye damage.
9 use gauntlet type gloves made from heat resistant material.
9 secure cylinders to a trolley , wall or post to prevent them from falling.
9 All cylinders should be used and stored in an upright position.
9 never drop or strike a cylinder. do not use cylinders that have been dented.
9 cylinder caps should be used when storing or moving cylinders.
9 empty cylinders should be kept in specified areas and clearly marked ‘emPtY’.
8 do not use oil or grease on any inlet connections, outlet connections or cylinder valves.
oil, dirt or grease.
9 examine hoses for cuts, burns or worn areas before each use. Also inspect fittings for damage. if any damage is found, replace
immediately.
8 do not repair hose with tape.
9 Always use reverse flow check valves on torch and flashback arrestors on the regulator. this greatly reduces the possibility of mixing
gases in the regulator or hoses. reverse flow check valves are an important safety precaution.
9 Working pressure on an acetylene regulator should neVer be set above 15psi (1 bar).
9 these instructions cover the use of the kits on mild steel. if used on any other materials, extra precautions will have to be
taken.
9 make sure that there is a good flow of air to the user and the tip, at all times. use a welding fume extractor if conditions are poor or space is
confined.
8 do not leave the torch alight and unattended.
9 for safety advice regarding gas bottles (oxygen and acetylene) refer to the supplier of the bottles.
9 make sure bottle keys are in place at all times so that in the event of an emergency the valves can be turned off quickly.
9 Keep hoses away from flame at all times. make sure that hoses are laid flat where possible and not in a position where they can be run
over by vehicles, which would result in permanent damage.
9 leaKing hoses can Kill. leak test all connections and valves prior to each use of the equipment.
9 if hoses are not long enough, join them together with the manufacturer’s couplings only.
8 do not join damaged hoses, they must be replaced immediately .
9 remember at all times Blue = oXYGen ‘o
8 At no time may you interchange parts contained in this kit with those of other manufacturers.
9 only sealey replacement items should be used.
9 Acetylene fittings have a left-handed thread and notches on hose unions to indicate this.
red = AcetYlene ‘A’
Keep all threads and unions clean and free from

4. preparation
warning! danger of explosion. All parts which come into contact with acetylene or oxygen, including hands and tools, must be
free from oil or grease. if grease or oil is found on a cylinder, discontinue its use immediately and contact your gas supplier.
4.1. preparing the cylinder. make sure that the cylinder to be used is safe and properly secured as noted in the safety precautions.
4.2. Whilst standing on one side ‘crack’ each cylinder valve. ‘cracking’ is to quickly open and close the valve allowing gas to escape and
clear the valve of any foreign bodies.
4.3. connecting gas regulators to the cylinders
note: Pressure reGulAtors should be treAted As Precision instruments And should not be JArred
or KnocKed.
4.3.1. function of the regulators. fitted to the outlets of the gas cylinder valves, the pressure regulators reduce the pressure of the gas
from cylinder pressure to the constant lower pressure required for the operation of the equipment. the left hand gauge indicates the
pressure in the cylinder. the right hand gauge indicates the pressure of the gas being delivered to the torch. Pressure reduction
within the regulator occurs in two stages.
4.3.2. Attach oxygen and acetylene regulators to the appropriate cylinders. on each gauge ensure the inlet filter is in place and is not
blocked or contaminated. if an ‘0’ ring is fitted to the inlet, check for damage and replace if necessary with an ‘0’ ring recommended
by the regulator manufacturer. do not use any form of jointing paste or tape between regulators and cylinder valves. before
attaching the gauges wipe the fittings with a clean dry cloth. screw the union at the base of each regulator to the appropriate
cylinder by hand. ensure that the gauge is correctly orientated so as to be seen properly by the operator in use. to tighten, turn
clocKWise for oXYGen, and Anti-clocKWise for AcetYlene. A wrench should be used to ensure tight connections.
4.3.3. close the regulators by turning the adjusting screws anti-clockwise to relieve the pressure on the diaphragm before opening the
