You use a water cooled Tig torch (Hand piece) for welding aluminium but their is no need to have a water cooled Tig torch for welding 3mm more like 5mm plus...... When you are tig welding a fuel tank you purge the tank with argon gas which means you have a separate gas bottle and regulator with the hose running straight into the tank this fills the inside of the tank with argon gas while you are welding the outside. This stops oxygen attacking the weld on the inside which can cause porosity in the weld (could be a leak down the track)
Hope this helps you out
Cheers Mark
