thinking of cancelling my account with BOC as the prices are getting silly, anyone know who else i can source from, northampton way
i get mine from Air Products never have had a problem with them.
rental of a medium cylinder works out about £11 a month.

gas direct near Newark are pretty cheap, about the same as air products the size W cylinder is £13 a month rental i think, then bout £15 to fill.
i get my refilled at my local fire extingusher refill place. there off the moseley road in birmingham as long as your bottle is in date there sweet. i uesd to get exchanged bottles with boc. expensive. ive got a pub gas bottle on my mig! costs me a fiver to refill
co2 is awful to weld with, and pub gas has a high moisture content so is all but useless. argoshield isnt even that expensive. why do people insist on pub gas?

pub gas bottle filled with argoshield, no shocking rental chargesOriginally Posted by hay_lewis_68
few problems with using pub bottles, if its marked on the underside the gas supplier can send it back and get a finders fee, and also if anything happens with my bottle i get it swapped same day free of charge.

Just a shocking noise as the bottle lets go.
The pressures involved are hugely different. A bottle of liquid CO2 is about 60 Bar, Argon is 300 Bar.

There should be no moisture in CO2 from a decent supplier, it forms an acid and corrodes the inside of the bottles, steel lines etc.
Pub gas these days is not CO2 anyway, it is a mix of CO2 and Nitrogen and the nitrogen makes it ropey to weld with, but not impossible.

i was wondering about the pressure difference, i'd not have a bottle rated to 60bar filled to 300bar in my garage!!
you can weld with no gas, its just a really really sh*t weld... just like using co2.

well i know of atleast 4 people doing this no bottles let go and one has been using the same bottle 15years
and ours at work are only filled to 200-250baras labelled on the bottle
for a company like you thats fine as you'll use a fair bit more than a hobby welder,
so it'll work out cheaper and by the book
but 7-10quid too fill it up at newark auto jumble 3times a year, beats a year of bottle rental.
pub gas bottles are now also filled with 25 % nitrogen so make your welds look awful and porus
well i got 3 old pub bottles here for free and seem to be relatively full, still have my BOC account for the argon shield. prob just the pub bottle on the bodywork metal for tacking etc
not when you get them filled with a different gaspub gas bottles are now also filled with 25 % nitrogen so make your welds look awful and porus
OK, well bottles should be inspected every 18 months for a start and the fill pressure for Argon is actually about 285 bar, but the cylinder gets hot, when it cools the pressure drops to about 250 Bars. It is this continual heating up and stretching of the the cylinder that causes the issues that mean a compressed gas cylinder needs testing every 18 months or so.well i know of atleast 4 people doing this no bottles let go and one has been using the same bottle 15years
and ours at work are only filled to 200-250bar
If your filling by a pigtail from a bottle at work then your not going to get the CO2 bottle uo to 250 Bar, but you should still get it well over the safe working pressure for the rupture disk on the CO2 bottle. It is inherently dangerous and I personally would not do it.

I always use pub gas CO2 No problems here. I get it free so not going to moan.
Manifolds,flanges,collectors,bends and car transport PM your needs.
we use pub gas at work any never had a problem with it
need more boost lol
When I worked for BOC we were promised £10 for any bottles recovered from anyone who misused them or if we found them dumped. But I never got anything for the ones I reported back to them.
Veni,Vidi,Scubi
surely you dont do this lol.
I can get a really good weld with CO2, not as good as with Argoshield or pure argon though, certainly more than good enough for car work. They do say a bad workman blames his tools though.

ive never used c02, maybe give it ago some day, but id rather stick with argoshield.
No monthly charge, just pay once for 3 years rental then pay for refills if you need it during that 3 years, very cheap

They are abit far from you but handy if you know someone down here + fancy a bit of a drive, even if you have to come the distance to collect still a big saving over boc prices
Have you tried Sureweld in Rushden? I usually get my wire etc from them too. Competitively priced.
when i get my co2 pub gas the asways ask if i want the co2 or co2 nitrogen mix and i never have problems with my welds looking **** or being porus ????? if you cant weld with co2 you have more of a problem that just the gas youve got
