Might be better off with a couple of alloy plates to sandwich the holes and some PU sealer using either pop rivets or nuts and bolts if using thicker alloy old alloy will be pitted

Over on the Wooden Boat Forum in the US, there was a long thread on the build of a 80/100 ft fireboat. All aluminium ( Obviously it was a bit odd on a Woody forum but was liked) They used fancy pulsed MIG welders, but this was thick stuff, plate rather than sheet. What ally do you have in mind? The Tinny would be pretty thin and if that needs repair, patches and rivets with mastic would be easier (I know, I know, you wanna TIG) Ours is probably not even the 1mm I thought it was.
Can't comment on pulsed MIGs for steel, but from what I have read, not of much use in the low thicknesses, if at all. ( I await an expert...)
Personally, I have been using a Kemppi 150amp Mig for the last 20yrs, including a bit of ally. I also have a DC Tig, mostly for stainless on boats. Much as I fancy an AC/DC Tig, I can't see enough use to even think about buying one. But, hobbies can justify all sorts of unrealistic spending
.
My first car was a Mini van. I tuned it to an inch of it's life, then turned it into a saloon with a light weight shell. Quicker than my bro's Downton Cooper S. Used to get pulled all the time (fuzz, not birds..) Then bought a Sunbeam Alpine, tuned that and drove just as fast, but without being pulled.

No idea about welding alloy but I use a pulsed mig at work for mild steel and stainless, when I'm welding thin sheet I turn the pulse setting off.

It's a Fronius Transpulse Synergic2700 I don't quite understand all the settings on it as in my last job I had an ancient Butters/AMT so the Fronius is the first modern set I've used.
I have it on the pulse setting mostly just turning that of for the thinner material as I find it easier to control.

KemppiFrog I love the story about the Mini Van. I have had 7 to date, of which one was for spares. The blue one in my avatar is my favourite by far. 1960 Austin Mini Van with S running gear, Minilites and a 1997 Single point injection 1275 Cooper engine. I used to to tow my gardening trailer around for years in the UK and in Australia and nearly tore the rear end out so I have it off the road now to restore the body to a good strong state.
The tinny is quite old and has thicker plate than the new ones. I had to stepdrill a larger hole for the drain plug and it verniers at about 2mm. The keel is fashioned from an RHS Ali section and this covers the join of the two lower sheets where it leaks in a few places so I want to seam weld it all the way to stop the leaks and give more strength.

Oddly enough I had one [in lovely Willow green
] and did the same. Remember having all four wheels off the ground once, the front suspension trumpets didn't like that......

Willow Green is a great classic colour. Some of the councils had them. I had an old white ex police one. I have been all four wheels off the ground in Rhodesian days I was being chased by an Austin Westminster police car and they didn't like the storm drains as we were going across them. Ha they never caught me. I think they wanted to chat about my noisy exhaust at 2am.
