Ok, few photo's of some of the welding on my Series 2 restoration - this is TIG welding with a LOT of experience - don't expect welds like this on your first attempt







(I know they're big - but if they're small you can't see up close and personal )

Few tips to welding:

Fire extinguisher
Make sure the welding equipment is set up right and you're using higher gas pressures if outside etc.
Make sure the area is bare metal and cleaned with a solvent like acetone
If sorting rust out - don't try and weld patches where it's gone through - chop a section out using a rule of removing 50% more than the rust patch - i.e if the rust hole is 4cm wide, go 8 centimetres, 2 each side for the hole.
Never try and weld over rust.
Avoid welding where there's waxoyl on the other side - it catches fire VERY quickly.

Hope that helps
