    Holidays... this is the best time of year for me, work wise. All the students go home and I can work merrily without having to compete for equipment. I take my holiday in spring or autumn to avoid the rush.

    Oh, I just bought one of those kits on ebay. Christmas present to me from me on behalf of my wife. :hello2:

    I like your thinking Tyrone. My wife asked me what I wanted so maybe this is the answer (I really want pressurised CO2! but that will have to wait)

    Thinking? I'm just well trained. She says buy and I buy. She made the mistake this morning of asking what I want for Christmas. You mustn't think, you must be quick!

    Didn't you see the links I posted from ebay? I am sure that they do welding in South Africa.. R150 for a 500gram bottle, and another R150 for a regulator.. :) hardly thousands..

    Why don't people use pressurised CO2? God knows why.. I do not know as well.. :)

    That one is from the same manufacturer, but has a better needle valve.
    I have been searching for a seller.

    Well found

    Nah, the Ebay one is better... simply because I bought it and want to feel good about myself.

    Luis, I don't have pressurized CO2 because I don't have space to put it. The only place I have for a CO2 system is behind my tank and a 1 L coke bottle just fits there. For others, even a few hundred Rands is a lot of money around here.

    :) yeah.. I understand about the money... this just seems the same price as the mig welder bottles.. :)

    How much you paid for it, including deliveries?

    About size, I will take a picture of my current mig bottles (I got two as spares), next to a coke bottle.. I think that the mig bottles are smaller..

    I tried DIY before, with good results, but it does not make economic sense to use it, there are cheaper ways.. :)

    One of the issues I have with South Africa is the inability to find reliable information online.. most shops are not online, or do not sell online.. it is always a pain to find something..

    So after a bit searching.. I found a seller online, they sell CO2 bottles, disposable ones, and cheap, R255.

    http://za.rs-online.com/web/p/mig-welder-accessories/0623170/

    I bought two adapters in the UK, and will be buying some of these bottles to use on a a couple of nanos..

    With less than R500 I will have a running pressurised CO2 bottle.. this to run 24/7, or if you want, just buy a solenoid and put it inline.

    If you look you find.

    damn - not sure how you found this - i was looking but clearly not in the right place. Will folllow-up tomorrow with them and see for a reg.

    thank you very much

    By the way, we all have the same problem in ZA - not everything online and not as much in terms of variety

    It was by luck.. I was looking for mig welders, and some guys wanted to fix a car, but did not want to rent the cylinders, so they were advised to either buy a Afrox bottle second hand then get it refilled (a very good idea), or to buy these, which are the same ones I get in the UK for £15. You just need to get a regulator, easy to find, or buy on ebay...
