    Flame Cleaning Head - Acetylene.

    Flame cleaning works by using thermal fraction, cleaning rust /oxide from plate is best carried out when the plate is cold.  The intense heat from the flame cleaning head, as it is passed over the layer of oxide, the thermal shock lifts the rust from the plate surface.

    To operate correctly a minimum of two industrial acetylene cylinders must be used to prevent acetone draw-off and subsequent operating difficulties.

    With the flames set to the correct "neutral" condition and burning freely to the atmosphere several of the cones should be lifting off the burner.  This indicates the correct flow has been set. The cones seat as soon as the nozzle is brought to the work surface.

    Gas Welding & Heating Nozzles FAQs

    Straight answers to the questions people ask most when choosing and using gas welding and heating nozzles.

    What is the difference between welding, heating and brazing nozzles?icon-minus-redicon-plus-red

    A welding nozzle gives a small, focused flame for melting metal and is sized for the thickness being joined. A heating nozzle gives a much bigger flame, often with many flame ports, for heating larger areas for bending, straightening, preheating or freeing seized parts. A brazing nozzle produces a softer, wider flame suited to heating the joint evenly without melting the parent metal.

    Some heads are specialised, such as flame cleaning heads for removing scale and paint. Choose a nozzle for the job you do, for your torch and for your fuel gas.

    How do I choose a welding nozzle size?icon-minus-redicon-plus-red

    Welding nozzles are numbered by size. The number relates to how much gas flows, and so to how much heat you get and the thickness of metal you can weld. A small number suits thin sheet and a large one suits thick material. The numbering systems differ between makers, so do not assume a number from one maker matches another's.

    Use the maker's chart for your nozzle, which gives the metal thickness and the pressures to use. A nozzle that is too small will not fuse the joint properly, and one that is too large can burn through thin metal or leave a messy weld.

    What are heating nozzles used for?icon-minus-redicon-plus-red

    Heating nozzles put a large amount of heat into a wide area. They are used to preheat thick steel before welding or cutting, to bend or straighten bars, pipe and plate, to free seized nuts, bolts and bearings, and to warm or dry parts before work. Multi-flame heads spread the heat evenly instead of focusing it on a point.

    Heat the metal slowly and evenly to avoid distortion and cracking, and remember that heated metal stays hot long after it stops glowing. Keep flammable materials away, and never heat a sealed or pressurised container or part.

    Can I use acetylene and propane heating nozzles interchangeably?icon-minus-redicon-plus-red

    No. Nozzles are designed for a specific fuel gas, because the gases burn differently and need different amounts of oxygen and different port layouts. Propane and natural gas flames are cooler at the tip than acetylene but spread a lot of heat over a wide area, which is why propane is popular for heating.

    Using a nozzle with the wrong fuel gas can give a poor or unstable flame, wastes gas and may be unsafe. Match the nozzle, torch and regulators to your gas, and use the maker's recommended pressures.
