From: Ozie on 24 Jul 2010 11:32 Well following advice on the welding forum i bought a Clark Pro90 today it came with a Co2 bottle and i bought an Argon/Co2 mix bottle. I will practice with both of these before i decide which large size bottle to buy as there is such a large difference in price. On the way home i was passing the local fire station which was having an open day, they were cutting the roof of an old Astra, so i managed to get the roof and bonnet to take home for welding practice. Thanks for everyone�s comments, although their still seems to be a Co2- Argon/o2 divide if anyones interested i will report back how the Novice managed. -- Oz

I always used my home address when getting new cylinders and BOC never queried it. I re-silled and A-panelled a Mini with it - including using lead filler - a great learning experience :-) However the main problem could be your home insurance - welding cylinders within a certain distance will invalidate it! If your garage is attached don't risk it but if it is at the other end of your garden check the distance. Slatts

A skilled gas welder can weld car bodies. I saw a resto on a Jag once where this had been done; they said too that the weld bead is not as hard as with MIG so it could be planished flat with a hammer rather than doing so much grinding. The old workshop manuals recommend placing wet asbestos around the weld to contain the heat! -- asahartz woz ere |
