hot air guns and soldering copper pipes
Hi all,
Does anyone know if electric hot air guns like this: http://www.screwfix.com/app/sfd/cat/...77285&id=14303 are any good for soldering copper pipes? What are advantages/disadvantages over propane blowtorch ? I will be laying new CH piping and want to get proper tool for the job. thanks for your help |

I did all mine (up to 28mm copper) with a £10 blowtorch, and it worked no problem at all. I can't imagine a hot air gun will have the power or ability to concentrate the heat where you want it (or the ability to see where the heat is going at all). -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

No, they are not.
cheers for that - saved me lots of frustrations ... The main disadvantage is that you won't be able to solder with the hot air gun. That's what I thought - I got the impression that's it's do-able when reading about steinel heat guns: http://www.engineeringlab.com/steinelheatgun.html In the middle of the page they show a picture of soldering copper pipes with their heat gun. I will be laying new CH piping and want to get proper tool for the job. That'll be one of these:http://www.screwfix.com/app/sfd/cat/...88230&ts=77814 many thanks for that - will use this one fueled by propane |

That's because it's a professional heat gun designed to solder pipe and the price reflects this. From the picture it would still take an ice age to solder 28mm pipe with the thing. |

Then use what everyone else uses - a blowlamp. The electric clamp types are near useless too. Your only real decision is which blowlamp to buy. If you will use one a lot, then the type with a separate gas cylinder and a hose to the torch is more expensive but cheaper to run. For just this job and occasional blowlamp tasks there's a vast range. I'd go for one where the re-fills are readily available. http://www.screwfix.com/app/sfd/cat/...87727&id=43225 Looks to be good value for the cost of replacement canisters and they appear to be a standard type. -- *I started out with nothing, and I still have most of it* Dave Plowman London SW To e-mail, change noise into sound. |

http://www.toolstation.com/search.ht...hstr=blow+lamp The very one I use. Which one please as the link gives (for me) 3 different blowlamps? Also, as I am a novice with soldering plumbing, can you give me a rough guide as to how many joints a cylinder should do in (say) 22mm pipe? (I shall apply my own divide-by-3 'cos I'll need to practice factor - unless 3 is not enough.) -- Robin |

(I shall apply my own divide-by-3 'cos I'll need to practice factor - unless 3 is not enough.) Mine - which uses those squat pierceable canisters - would do so many you'd not bother counting. Certainly no need to have more than one spare canister per day given normal rates of one man working - but Screwfix sell them in packs of 5 anyway. Worth also laying in a supply of disposable lighters for lighting the blowlamp - I reckon these are cheaper and more reliable than the self igniting kind. One tip you may find useful - spare ceramic tiles no longer needed are handy as heat shields. -- *Generally speaking, you aren't learning much if your lips are moving.* Dave Plowman London SW To e-mail, change noise into sound. |

This is the one for most people who don't need something for constant heavy use. Look on the shelves of your local DIY store and you'll find one. 'Taymar' is a common name. I can't help with a specific figure for number of joints from one cartridge (depends on so many variables) but I can say that they're not so short-lived that you need to worry about constantly running out.

Could do with it this weekend too as the rape is going over and the honey will have to whipped off. Thanks for the heads up on that. Rob |

(I shall apply my own divide-by-3 'cos I'll need to practice factor - unless 3 is not enough.) If you are a novice practice first before soldering in anger. Tube and bulk end feed fittings are cheap enough to allow this. After soldering a trial say 22mm tee, take it apart by re-heating and see how well it has tinned. One tip is to watch the colour of the flame - it goes sort of green when the copper is hot enough. -- *Seen it all, done it all, can't remember most of it* Dave Plowman London SW To e-mail, change noise into sound. |

I bought my blowlamp in November last year and I changed the original cartridge 2 weeks ago. Cartridges are easily available though - buy two when you buy the blowlamp & when the first one runs out buy another as a spare - that way you always have a full one in reserve. -- Dave The Medway Handyman www.medwayhandyman.co.uk 01634 717930 07850 597257 |

(I shall apply my own divide-by-3 'cos I'll need to practice factor - unless 3 is not enough.) I've used 2 canisters I think (maybe plus the original) although one of these was double sized. That's a whole central heating system, and completely replacing all the plumbing in the kitchen and bathroom, and new 28mm gas feed full length of the house, all done in end-feed capilliary fittings. Plus the odd bit of plumbing for other people. The double sized canister can make it harder to use the blowlamp in small corners. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

They will work.

However - they are far from ideal for domestic plumbing jobs as they take some time and have far too much heat spread with the risk of damaging surrounding items, a blowlamp is much better. I agree. They work under ideal conditions - making bits of pipe up on the bench, but for anything else use a gas blow lamp. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |
