Oxy-propane and oxy-propylene kits: buying the right one

You have decided to use oxy-propane or oxy-propylene instead of acetylene, or you are setting up a torch system from scratch.

The next question is practical: which kit do you actually need?

Cutting, heating, brazing and lead welding each place slightly different demands on a torch. Choosing the wrong set could mean paying for capacity you never use, or struggling with a nozzle that is not suitable for the job.

This guide matches the job to the kit, explains what each set includes, highlights what else you may need to add and points you towards cylinder sizes that suit your workload.

If you are still comparing acetylene with propane and propylene, read the companion guide on oxy-propane as a practical acetylene alternative first.

This page assumes you have already made that decision.

First, the fuel gas: propane or propylene?

Propane and propylene are both LPG-family fuel gases.

Both are stable, easy to store and run on the same regulator and nozzle family, so one fuel-gas set will cover either option.

In simple terms, propane is the most economical choice for steady cutting, heating and lead work.

Propylene burns hotter and reaches cutting temperature more quickly, making it suitable for heavier sections and higher-throughput cutting.

For the full comparison, see the acetylene alternative guide.

You can also browse cylinders on the propylene and oxygen pages.

Match the kit to the job

Adams Gas supplies complete, ready-matched oxy-fuel kits, so the torch, nozzles and regulators are already sized to the gas.

The Oxygen Propylene Heavy Duty Cutting Kit is designed for cutting steel plate and section.

It is built for clean, sustained cutting with a cutting attachment and matched nozzles.

The Oxygen and Propylene Heating Kit is designed for pre-heating, bending and freeing seized parts.

It provides broad, controllable heat over larger areas.

The Oxygen Propane/Propylene Lead Welding Kit is designed for plumbing, roofing and heritage lead work.

It provides the fine, controllable flame needed for lead welding.

For brazing and silver soldering, either the heating kit or the smaller nozzles from a cutting kit will do the job.

The hotter propylene flame is useful on heavier joints.

Adams Gas kits currently start from around £224 excluding VAT, although the product page should always be checked for the live price, as Adams Gas prices are trade and exclude VAT.

When a kit is the wrong answer

If you are joining thin mild steel by fusion, or carrying out volume fabrication, oxy-fuel is not the most efficient tool.

That work is better suited to MIG or TIG welding.

The fuel-gas kits above will be frustrating for that type of work.

For shielding gas requirements, see the welding gas mixtures guide.

What is in a kit, and what else will you need?

A ready-made oxy-fuel kit typically includes the parts that need to be correctly matched to one another.

This normally includes the torch handle, a cutting or heating attachment, fuel-gas and oxygen nozzles, twin hoses, with blue for oxygen and orange for fuel, and flashback arrestors.

You will then need to add the items around the kit.

This includes a propane/propylene regulator.

This is fuel-gas specific and is not the same as an acetylene regulator.

The Propane/Propylene Regulator with gauges, from around £49 excluding VAT, is the correct part.

You will also need an oxygen regulator if your kit does not include one.

You will need a fuel-gas cylinder, either propane or propylene in 2L, 10L or 20L sizes.

You will also need an oxygen cylinder sized to your workload.

Consumables such as spare nozzles and, for brazing and lead work, the correct rods and flux should also be considered.

Always confirm exactly what each kit includes on its product page before ordering, so you buy only the regulator, cylinders and extras you still need.

Cylinder sizes: match the bottle to the workload

The kit is a one-off purchase, while the gas is the running cost.

This means it is worth choosing cylinder sizes that suit the way you work.

Adams Gas supplies oxygen for heating, cutting, brazing and lead welding from a compact 95L bottle, starting from around £24 excluding VAT, up to 220L.

Propylene is available from 2L through to 10L and 20L cylinders.

A mobile plumber or lead worker carrying out occasional joints will usually be well served by the smaller bottles.

A workshop cutting and heating every day will benefit from larger oxygen and propylene cylinders to reduce the number of swaps.

Because Adams Gas operates on a refill and exchange basis, you can start small and increase cylinder size as the work grows.

Using oxy-fuel safely

Oxy-fuel should always be treated with care, whatever gas you are using.

Use the correct fuel-gas regulator and nozzles.

Fit flashback arrestors on both lines.

Check hoses and connections for leaks before lighting the torch.

Work in a well-ventilated space and keep cylinders upright and secured.

Always follow the safety information supplied with each cylinder.

If a setup is unfamiliar, ask for advice before lighting the flame.

Supply without the rental trap

Equipping a torch setup is also an opportunity to remove a standing charge from your business.

Adams Gas operates on a refill and exchange basis, with rent-free cylinder options.

This means you pay for the gas rather than a monthly fee to keep the bottle.

With UK delivery and a nationwide stockist network, a refill is rarely far away, whether you run one van or several sites.

You can view the full bottled gas range and welding gas supply online.

If you run a trade counter or hire shop and would like to supply oxy-fuel kits and gas to your own customers, you can become an Adams Gas stockist.

Frequently asked questions

What is in an oxy-propane torch kit?

A ready-made oxy-propane or oxy-propylene kit includes the matched parts, such as a torch handle, cutting or heating attachment, fuel-gas and oxygen nozzles, twin hoses and flashback arrestors.

You will need to add a propane/propylene regulator, oxygen and fuel-gas cylinders, and consumables such as spare nozzles and brazing rods.

Always check the individual product page for the exact contents.

Which kit do I need: cutting, heating or lead welding?

Match the kit to the job.

Choose a cutting kit for cutting steel plate and section, a heating kit for pre-heating, bending and freeing seized parts, and a lead welding kit for the fine, controllable flame needed for plumbing, roofing and heritage lead work.

Brazing and silver soldering can be handled by the heating kit or by the smaller nozzles from a cutting kit.

Do I need a special regulator for a propane or propylene kit?

Yes.

Propane and propylene use a fuel-gas regulator, not an acetylene regulator.

For example, the Adams Gas Propane/Propylene Regulator with gauges is suitable.

Propane and propylene share the same regulator and nozzle family, so one fuel-gas set covers both gases.

Can I use a lead welding kit for brazing and general heating?

The Oxygen Propane/Propylene Lead Welding Kit is built around the fine flame required for lead welding.

It can also handle light brazing and localised heating well.

For broad pre-heating over larger areas or heavier cutting, a dedicated heating or cutting kit is the better match.

Where can I buy oxy-propane kits and refill the gas?

Adams Gas supplies complete oxy-propane and oxy-propylene cutting, heating and lead welding kits, fuel-gas regulators, and propylene and oxygen cylinders.

These are available with UK delivery, refill and exchange, rent-free cylinder options and a nationwide stockist network for local supply.
