[Garry Spight]

Hi been trawling thru the pages on here trying to find what gas to use for thin mild steel.
Im using a clarke 100EN been using disposibles at the min but want to convert to a big bottle.
What gas is the best to use is it argoshield?
can I run this on a big bottle?
Where can i get it from? I'm in hertfordshire

Argosheild light. BOC product -- IIRC, it's 5% CO2 -- but everyone has an equivalent. AirLiquide are usually cheaper on rentals, yellow pages or the interweb.
