Hi all,

Realistically, what is the thinnest gauge of steel one can satisfactorily
weld using an arc (stick) welder before blowing holes makes it next to
impossible? (I'm not talking about some time-served, fully skilled, coded
bloke with all the certification; just an experienced DIYer.)

Stick? Prolly 1/4" :-)

maybe someone out there can do down to 2mm but I cant.

Seriously, if its thin consider brazing with a blowlamp



+1, I always silver solder if I want good integrity on finer stuff (not
necessarily just sheet). A set of vermiculite blocks to make up little
"brazing hearths" is very useful. You only need a propane torch
especially with the lower melting point silver solders.
