Ideally you need Argoshield which is a BOC Argon/Co2 mix you rent the bottle about �45pa for the smaller size and �34 for a refill or buy the bottle and gas outright from http://www.welduk.com/Results1.asp?Category=65 �90+del and �40 refill +del Alternatively you can use pub Co2 its quite possible to produce reasonable welds with this, despite what some may say, but it _is_ harder to use. cost is usually �15 returnable deposit on the bottle and �9.50 for a refill. If you are anywhere near E-Sussex Sellergas (no that's not one of my usual typo) do it for that price. -

No worse than with thin steel, ie needed fettling to look good. But it was about 5mm thick. Just turned everything up full. ;-) The tip needs to be a couple of sizes bigger than the wire to allow for expansion. -- *Growing old is inevitable, growing up is optional Dave Plowman dave(a)davenoise.co.uk London SW To e-mail, change noise into sound.

Mig keeps the heat more localised? -- *Don't join dangerous cults: Practice safe sects* Dave Plowman dave(a)davenoise.co.uk London SW To e-mail, change noise into sound.
