Blow torches and burners for a wide variety of industries
In this section any of the Standard burners (those without /01), extension tubes, and multiple burner adaptors can be fitted to any of the blow torch handles nos 1185, 1185/01, 1245 and 1340. The connections all have 1" x 26 tpi whit form threads.
(Note that Handle 1185/02 has a different burner connection and this goes with Burners 1230/01, 1470/01, 1472/01, 1473/01 - these burners cannot be fitted to the other Torch handles - the connections all have 9/16" x 26 tpi whit form threads).
The Extended torch handle 1345 can take any of the burners and the multiple burner adaptors.
New LPG Poker just introduced for the fast lighting barbecues, hog-roasts and outdoor fires. No 609 and 6095
Kiln - see Uses of Torches below for a suggested layout for a burner in a kiln or oven.
Pressure Equipment Regulations 2016 These torches conform to these regulations.
Use of Torches
General uses of torches
Some of the uses of a Bullfinch torch are:
- Soft and silver soldering
- Central heating installation - capillary joints
- General plumbing work
- Factory maintenance work
- Public utility work
- Telecom work
- Electrical work
- Gas installation
- Tube bending
- Paint stripping
- Jewellery work
- DIY work
- Electrical work with soldering attachment
- Plastic tile laying
- Heat shrinking of sleeves and plastics - e.g. cable jointing for Telecom and electrical installations
- General household jobs
- Removal of fungal growth from beehives
- Other agricultural uses such as removal of feathers from bird carcasses
- Pottery kilns - see below
- Blacksmiths forges
And for larger burners in Standard blowtorch range:
- Bitumastic work
- Roof laying
- Torch-on roofing
- Weed burning
- Large pipe work - e.g. weld pre-heating
Uses of Autotorch brazing system
In addition to the uses shown which these brazing burners will usually do faster, the brazing system is ideal for silver soldering of copper pipes and as a portable bronze brazing system for the following areas of work:
- Steam fittings installation
- Model engineering
- Heating and ventilating
- Agricultural machinery maintenance
- General engineering repair
- Appliance repair
- Lighting barbecues
- Lighting braziers, coal and coke fires
- Technoweld aluminium brazing
The Autotorch acetylene system
Has improved performance over the Autotorch brazing system and is particularly good for Bronze brazing and Technoweld work.
Bullfinch standard burners can be used for providing the burners for kilns. Most kilns have different requirements and so it is hard to give specific advice. We do have an informal information sheet on how our burners may be set up for a Kiln suggested layout - click here. It is important to remember that the burners do require space round them to allow air to be drawn in for combustion at the front and the back of the burners.
Technical information: flames
Although the flame temperature of an LPG (propane or butane) air burner at the hottest point is approximately 1900oC, the actual temperature a heated component can attain is much lower than this and depends on the burner, and the thermal properties of the component and its surroundings.
Acetylene-air and MAP//Pro gas-air will give flame temperatures 200-300oC above this and component temperatures 200-300oC higher too.
The Autotorch brazing burners can give temperatures up to 950oC under general conditions and up to 1200oC in ideal conditions only. They can therefore bronze braze under most conditions as well as being able to make faster soft and silver soldered joints. They are particularly good for hard/silver soldering of copper pipes.
The Autotorch 2300 series burners, the Autotorch System 2 burners and the Standard torch burners can give temperatures up to 800oC under general conditions. They are, therefore, ideal for soft and silver soldering and lead welding, but cannot be used for bronze brazing.
The Autotorch acetylene burners can give temperatures up to 1100oC undergeneral conditions and 1350oC under ideal conditions and can be used to do bronze brazing as well as the other general uses of torches discussed above.
MAP//Pro gas used on the FirePower, AutoPerformer and Performer torches will generally achieve temperatures between the Autotorch brazing burners and the Autotorch acetylene burners.

Gas supply for Standard torches
For use at high pressure (0.35-2bar) with propane and for continuous use the minimum size of cylinder is shown in the table. Butane cylinders now only have clip on connections and high pressure regulators (1bar) needed for our torches are not available - so these cylidners cannot be used for our torches,
These burners can be fitted to a manifold using a Burner adaptor No 1073. The burners have a 1.0in x 26tpi Whit form female thread.
Are not needed for these torches (download letter from HSE for verification).
Any of the Tinyregs or Bijou regulators. The No.1051 variable Tinyreg for propane is recommended to give the best results from these torches.
4.8mm high pressure hose to BS.3212/2 (no.1299) only must be used, with suitable hose clips
