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?

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.

Will a nozzle fit my torch?

Nozzles must match the torch they are used with. Torches differ in their connection, in the way they mix and feed the gases, and in the fuel gas they are designed for, so each torch has its own series of nozzles. Injector (low-pressure) designs and positive-pressure designs, for example, need different nozzles, and nozzle-mix torches use their own type too.

Check the torch maker's list for your model or the markings on your old nozzle. Do not force a nozzle that does not fit or mix parts from different makers, because it can leak or cause a flashback. If you are not sure, our team can help you identify the right one.

What are heating nozzles used for?

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?

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.
