Thanks Lotus 30. Not sure of the landrover thickness i thinks its 18/19s gauge? i should know really. My gauges are'nt marked ?? but i'm quite experienced at gas welding steel and i usually run equal pressures 2psi both oxy/acet for thin steel. I have a third gauge on the oxy. to trim it at low pressures.your gauges will be marked at the normal gas welding setting what thickness is the ali.
I have a mate who is a far better tig welder than i am and his land rover needed some patching up all the welds cracked outside the welds.
best get on to the tutorials about gas welding aluminium.
I will say i am only an amateur who has a passion for old cars. The knowledge on hear far out ways what the little i know.
