    Hi mate, welcome.

    Argon? I think you'll want co2 mainly to start learning.

    What does the bottle say on it.

    Generally, rental bottle, rental free bottle, or disposable. How big is it?

    Halfords sell little bottles.

    Is there any indication on the empty cylinder who owns it or who supplied it, and what date, if any, is on the plastic disc under the valve?

    Argon is just for stainless and aluminium ect.

    Mild steel co2 with a hint of argon iirc.

    That's pure argon, no good at all for mig welding.
    You need either CO2 or Argon/CO2 mix.

    When it's Argon or Argon mix there is not a lot of difference in the weight! With CO2 there is as it is stored in the bottle as a liquid

    Id not be buying a 2nd hand bottle because you dont know whats left in it and the bottle may not be his to sell.

    Theres plenty rent free deposit only for that sort of price- new sealed bottle
    Or get on the BOC which incurs a £50 yearly rental as well as other charges - look in "Welding gas" thread

    Argon + CO2 mix IS what you need. The problem with the one you are quoting is again getting it refilled when it is empty. It might be that that one is a type that can be refill but you need to be sure.
    Another option would be to use straight CO2 only. This will require a different connection on the regulator (that has come with your welder?) You could then use pub gas (make sure it's straight CO2 and not a beer mix) or a CO2 fire extinguisher turned up side down works as well. See pic (bit crude but cheep).
    You have not said what make and model of welder you have yet.

    That is worthless to you, as soon as you've used the gas up you won't be able to get it "refilled" anywhere without opening up a rental contract.
    (Refilled is a common term used on here but in actual fact it's an exchange service, you take an empty back and they exchange it for a full one.)
    My advice is to do it properly with an agent, buying a second hand one just isn't worth the hassle anymore.

    SGS Gas is a good option if your not welding that often

    Nice sturdy unit. So long as works then should be a work horse. Main thing to watch for is having the spool of weld wire "external" it will tend t rust if condensation settles on it or grinding dust gets on it. Use an old bead sheet over the machine (and wire) to protect even if kept in a garage/shed. Once you get use to using it you will be able to whip the spool off and keep it bagged (and in the dry) between welding jobs.

    Well if it works then yes that's a very good price. One other item you may need to get is a new liner for the torch as it's had wire sat in it for some time. Item is a consumable. Should be £10 for one on ebay (make sure yo get the right length) can't tell if that is a 3 or 4 meter torch. You can cut a 4 meter liner down to 3 but not so easy to grow it :whistle:.
