CWS Mini Model "O" Lead Welding Torch Set
Improved value - larger oxygen cylinders.
This large oxygen cylinder is the standard M10 right hand thread. The benefit is that this new larger canister has 4 times the contents over that of the small original disposable canister size.
When it comes to lead welding torches then ours is possibly the best in the market. We don't just buy and sell any old torch and say it is produced to a UK design, technically all Model O torches are. It is after all a British torch type.
Our Model O torch flame does not adjust when you turn your hand over to start working with the lead, The flame size that you set will not adjust at the smallest of knocks on the valve knobs. It will perform beautifully and adjust accurately to your needs with a precise and stable flame.
Every Model O torch that arrives to us is fully stripped down, machined, assembled and tested before we sell them. How do we know this? We do it all ourselves in Cheltenham. If it doesn't have our own brand logo 'CWS' on the torch then it may not perform to the standard that you would like.
Every torch after it has been worked on gets reassembled with UK produced O-rings and every Model O torch is leak tested at both low pressure and high pressure. To help prove consistency of quality for our torches we also flame test 10% of torches at random.
The video tab contains a video showing just how reliable the flame adjustment is on the torch and how it compares to other competition in the market.
Of course, a top quality lead torch is nothing without a top quality welding tip. All our Model O propane welding nozzles (sizes 1 to 5) are finished by ourselves. This ensures you get the quality that you really deserve and of course you get a proper flame shape making use a lot easier. Please continue this trend and when you need more tips make sure it is CWS tips.
We don't stop at the best quality lead welding torches either! We supply this particular Model O setup with 2 meters of hose and not just the chunky standard bore hose. Our hose is specially produced for ourselves and adheres to BS EN 3821 despite not being required to. This hose is super flexible and you barely notice the hose on the end of the torch. This makes holding and using the torch much easier and should enable you to get a neater finish on your lead joint / welds.
At Noz-Alls we always try to do things sensibly, some suppliers of slightly cheaper kits have the hoses fit directly to a nipple on the regulator. If and when the nipple snaps from an accidental knock they are unfortunately faced with having to buy a new regulator. Our hoses, no problem. No built in nipples to the regulator and the nipple in the hose is quick and easy to change if you were to damage it or the hose. Not to mention miles cheaper than a new reg.
There are some cheaper options in the market which do not include true flash back arrestors. We however adhere to the safety guidelines of BCGA (British Compressed Gases Association) which stipulates flash back arrestors must be used. When it comes to personal safety we don't mess around. The flash back arrestors on our mini lead welding setup are the same industrial quality as we would supply to a standard gas cutting and welding set. They are German made, BAM approved flash back arrestos fitted with a non-return valve (NV), thermal protection (TA) and a flame arrestor (FA).
Continuing along the line of a proper good quality portable propane Model O setup - we have also kept things simple when it comes to gas. No bespoke threads, no manufacture locking you in to just one brand of gas. The propane cylinder can be bought from any decent DIY or plumbers store (and us too), the oxygen bottle is the most standard oxygen bottle available M10 right hand thread. No silly M12 thread or backwards threads to keep you locked in. Just good honest standard bottles which now includes the better value larger oxygen canister.
The set now includes our improved gas stand - this version has a canister clamp which holds two canisters, either propane (blue) or propylene (yellow) plus the larger longer lasting oxygen canister.
If you only use the smaller oxygen canisters please see our orignal set which includes the canister clamp for two standard size disposable canisters, one oxygen and one fuel gas.
Why not use MAPP in the yellow canister?
Once upon a time when MAPP was a mixture of methylacetylene plus poly -propadiene it was a hotter and better gas than propane. True MAPP has however been an obsolete gas for a long time now. Manufacturers still sell a yellow can of gas and call it things like MAP Pro or MAP Professional but it is in fact just propylene which all told is about 30 degrees C hotter than standard propane. The small extra temperature gain is not why we add the propylene to this set, the extra cost of propylene is worthwhile because burning the propylene uses less oxygen making the set more ecconmical providing a longer run time.
The final thing, every torch we sell comes complete with a table of pressure settings and which nozzle size to use and when. It may prove helpful when it comes to setting up. Keep this handy or just refer to our website images while on the roof!

At Noz-Alls we do not make false claims about our equipment, artisans which use our Model "O" Lead welding set understand how good it is and why it is better than others sets which may look similar, at a lower price.
Important Note
Please be aware that there are no main stream industrial regulators with built in flashback arrestors - it is impracticable and too costly.
When it comes to "lower" end of the market for disposable canister regulators the cost would be really prohibative, to build in a Flashback arrestor. Therefore, despite what some website are claiming
there are no disposable canister regulators which have a built in flashback arrestor - they do not exist.
Do not believe what their website states.
Any Flashback arrestor would need to be manufactured to BS EN ISO 5175-1 (was 730-1). Noz-Alls provide BAM approved FBA with G1/4 threads to connect to the regulator outlet.
Second Note
Hoses may be fitted with HCV - Hose Check Valve - which is a simple non return valve.
The HCV is NOT a flashback arrestor and the HCV does not stop a flashback.
The HCV is supposed to prevent the backfeeding of gas only.
At Noz-Alls we do have torch mounted Flashback Arestors, they are larger than the HCV and more costly than the flashback arrestor we mount to the regulator.
The regulator mounted FBA has a non-return valve and temperature actuated valve plus of course the dense flame arresting element.
Third Note
Oxy / Acetyene when set with a nautral flame has a temperature of 3106 degrees Celsius. This is the hottest you will achieve and may be used to fusion weld because the flame is "neutral".
All commerciall available "LPG" based gases when burnt with oxygen are below this temperature (3106C) - generally the maximum is around 2872C for propylene (yellow can) with other gases being lower - propane is 2810C and Butane 2814C.
Do not believe the tempeartures promoted by other websites.
Lead welding is not fusion welding in the true sense so may be carried out with most alternative fuels.
Due to the oxidising flame the other gases cannot be used for fusion welding.
