The bloke that i brought my welder from said to get hold of a pub co2 bottle and adaptor to suit.
Is this true, as you save a shed load of cash

Question for you gents, is there any need for argon in your shielding gas?,

With CO2 you get more penetration but also more spatter. With thin wall tube I would go Argon/CO2, easier to work with and you will get a better finish.
As a convert from CO2 to Argoshield light - I can definately recommend a mix. Makes me look like a reasonable welder.
A BOC contract, or similar, aint too expensive really - I paid about £30 for a years bottle hire (what I dont use refunded) and its about £30 for a
fill of gas worth 40 of the little bottles you can get from motor factors for a tenner.

I like the Coogar 5, an argon mix in a rebnted bottle from Air Products, similar to BOC I expect, just depends on whose got the nearest depot. Much
prefer it to CO2.

Mig welding with Co2 is hard work compared with modern argon mixes, also you really need a bottle heater as the gauge tends to freeze up, even with a
heater under prolonged use the gauge and bottle freeze. Although you prolly wont experience this with short welds.
My advice is stick with argon and make life easy for yourself. If you ask around you may be able to get argoshield through the back door of a local
welding shop, saturday mornings are usually a good time to ask,while the gaffer is still tucked up in bed.
I used CO2 mainly cos the 'piddly bottles' you can buy from machine mart have 60% or so more in them for same price.
However, its possibly a false economy.
The majority of my car was done with CO2 alone, and I can agree with the spatter thing. Means more tidying up afterwards.
Given the choice, go for a mix.

ps - im not a welder - this is what I have found from my own small experience.
Argoshield is the way to go, I'm on my 3rd large bottle, can't imagine what it would have cost in small ones.
Looks like I best start saving up for after christmas.
Thanks for all the help guys.
Take care Dan.
