Hello everybody. I learned to gas weld at college in the '60s and have gained skills in "Stick welding and MIG/MAG as the years have gone by. Never learned TIG though, but you always need something to aspire to don't you?
Anyway, now retired and in my early 70s I find I'm very much now what you would call a "hobby welder". I've had a BOC "Y" size bottle - approx 20 litres I think - (argon/ CO2) for my MIG for many years but really it's much bigger than I need and the hire charge is crippling (bill for £70 for the next year just came in) So I'm looking at the "Rent Free" cylinders. There's quite a choice isn't there? Anyone on here got any experience with suppliers?
The BOC product is an Argon CO2 mix with a "sniff" of oxygen and I notice the Hobbyweld is the same so maybe filled with a BOC gas? The SGS product is an Argon CO2 mix without the oxygen. I understand the oxygen "smooths" the weld slightly but as I've been using a genuine BOC product for years I don't know if I'd notice the difference changing to an Argon CO2 mix without the Oxygen? I ask because SGS fill all their cylinders to 200 bar whereas the other providers only fill their larger bottles to this, the smaller 10 litre bottles (which is the size I'm interested in) they only fill to 137 bar So the SGS bottle interests me a lot as my regulator can handle the BOC standard 230 bar service - even if the SGS gas is "only" an argon/cO2 mix. Also my local factor deals with SGS and can supply me immediately with refils guaranteed. As they are only 5 minutes away I'm very tempted.
Anyone like to give advice?
Thanks Jock
