    I need to weld some, aluminium on a job where a water hole has broken out can i just tack it over the top or do I have to put a copper or steel rod down the hole and weld and then pull the rod out my experience of aluminium is very limited I can get a bottle of argon in the morning and I have some 1.2 alloy wire and a gun with a Teflon liner is it likely to puddle and all drop through

    Thanks in advance

    How thick is the tank, 1.2mm wire may be too thick for it as the amps needed to burn it without a cold start will just blow through.

    TIG would be best suited unless it’s. Of decent thickness then you may want to weld a patch over it
