1. SAFETY
Always have a fire extinguisher nearby.
9
Never use oxygen or fuel gas to blow soot or dirt from your clothes.
9
DO NOT wear ragged clothes, as sparks can ignite the ragged or loose ends.
8
Always wear goggles or a helmet with the appropriate shade lens.
9
DO NOT use shaded safety spectacles or unshaded face shield visors for cutting or welding. They DO NOT stop the harmful rays which
8
cause eye damage.
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'.
9
DO NOT use oil or grease on any inlet connections, outlet connections or cylinder valves. Keep all threads and unions clean and free from
8
oil, dirt or grease.
Examine hoses for cuts, burns or worn areas before each use. Also inspect fittings for damage. If any damage is found, replace
9
immediately.
DO NOT repair hose with tape.
8
Always use reverse flow check valves on torch and flashback arrestors on the regulator. This greatly reduces the possibility of mixing
9
gases in the regulator or hoses. Reverse flow check valves are an important safety precaution.
Working pressure on an acetylene regulator should NEVER be set above 15psi.
9
These instructions cover the use of the kits on mild steel. If used on any other materials, extra precautions will have to be
9
taken.
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
9
confined.
DO NOT leave the torch alight and unattended.
8
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
9
over by vehicles, which would result in permanent damage.
WARNING! LEAKING HOSES CAN KILL. Leak test all connections and valves prior to each use of the equipment. Ensure hose
fittings are sufficiently tightened to the torch, We recommend to tighten both joints at the same time using two spanners to offer counter
resistance whilst applying sufficient pressure to tighten all connections to ensure no leaks and no damage to the torch.
If hoses are not long enough, join them together with the manufacturer's couplings only.
9
DO NOT join damaged hoses, they must be replaced immediately.
8
Remember at all times BLUE = OXYGEN 'O
9
At no time may you interchange parts contained in this kit with those of other manufacturers.
8
Only Sealey replacement items should be used.
9
Acetylene fittings have a left-handed thread and notches on hose unions to indicate this.
