how much does one of those cost?!?
I went to Halfords today, as advised, to get some brazing rods. The only ones they had were flux coated, are these the right ones?
And the fella working there said that a blowtorch wouldn't get them hot enough to melt, that only an electric arc or an oxy-acetylene torch. Is
this true? cos if it is then thats trouble....
his own words were 'nowhere near hot enough'.
any advice? thanks in advance.
Sexy ahotaline is the only way to go
goddammit
how much does one of those cost?!?
Second hand set are usually £50-£100, but its the rental on the bottles which is the killer. They are really useful though, cutting, bending, welding, brazing, freeing of siezed components..........had better shut up now or I will talk myself into a set!
I nearly bought a set. machine mart do a set for 200 quid that has everything you need except the bottles. bottles are something like 35 quid a year rental each (so 70 for both) and similar money for a refill. BOC gear looks the tits but costs more (like twice as much)
ive seen some complete sets with a trolly on ebay recently and think it was about 80quid or somthing, not too bad. i think it was listed as a porta
pack so trolly might be for small bottles. shes got a set a lean tits that welders daughter!! 
Russ.
Porta Pack is BOC's own make, very small bottles, but works well
Had the chance to pick up a set cheap not so long ago, very useful as mentioned above. Highly recommended, just knock the cost off of the £250
BTW I've heard that some people manage to aquire BOC bottles from sources other than BOC and then find a local account holder who will exchange
them on their behalf for a suitable cash adjustment, thus saving the rental and filling charges.
Surely this can't be cricket

b@q do a map gas / oxy little set for £35 - £40 ok if your just doing the odd one off not for large scale use tho

you have u2u
I have a brazing attachment for my arc welder. I have had it for years, it uses two carbon arc rods which you touch together to start the current flow and then move apart to produce the flame. It has always worked well enugh for my brazing needs.
Andy,
I've often thought about trying one of those things - they seem a bit scary though!
How difficult is it to maintain the arc, i.e. how often do you have to adjust the carbons? And how long do they last?
How close do you have to put the arc to get the braze to run?
cheers,
David
As I said, it has always worked well for me. Once the flame is set right it lasts a few minutes before the gap between the rods needs adjusting. As
for the carbon rods themselves, they last for ages. Whilst I don't do much brazing, I have had my set for probably nearly 25 years (my god, that
makes me feel old!!) and doubt if I have used more than half a dozen pairs in that time - need some new ones at present though!
I have never found it scary to use, and it is good for freeing seized component and can even be used to cut through metal sheet - although not very
accurately, but I have used it when cutting up cars.

It wasn't real, they were actors and he was only pretending.. A cutting torch makes more sparks to impress the kids who watch the program. It
would work on thick metal like girders.

Bought myself a Blowtorch and some brazing rods from Halfwits yesterday and Brazed my oil pickup pipe last night - no problems at all.... The brazing
rods I bought were expensive (about £3.50 for 2 !) but were marked up as 'for use with a blowtorch' - It certainly did the job for the pick
up pipe - dunno how it would cope with a larger job though.
Also picked up a 'disposable' bottle of Argon/CO2 mix for my shiny new MIG welder £7.99 - is that cheap??
Pretty much the same as machine mart, but it is still cheap innit? feels like a waste of the bottle though doesn't it throwing it away so
often?
in the little row at halford i couldn't see the blowtorch ones, maybe they dont have those in leeds... bummer.
might just buy an original sump and let the speedbumps chop it down to size...

When we were site welding and cutting I've used a burning torch to gas weld or braze BUT using one trick.
The torch was pushed hard down into clay soil and the multi hole nozzle blocked. I then used a nozzle cleaner reamer to clean one hole only. This
then made a nice small flame with which to weld or braze. Thing is, on site it was easy to clean again and go back to cutting.
Done many a 'homework' job that way in the past.
a mate round the corner has taken it to tig it, apparently hes good so we shall see. i reckon with the argon mix it might've been leak free.
as soon as I have sourced some suitable plate I will be mig'ing mine - so fingers crossed....
