I know they ain’t your favourite but they may be more preferable than the bulky size of a wp18 but you could look at the speedway sw320 as a torch option.I think a 3.2 filler rod may have made the difference but then again I have no real experience with tigging 12mm Alu so.....
Yes, got it to test out to make sure it will do what I need. Looks like it will so far but I will have to wait until I get a WP18 torch hooked up before I can get it at full amps.

320 amps at 100% on dc
270 amps at 100% on ac.
So that’s a better duty cycle than the machine itself but it’s a wp20 size torch. (Not round handle either)
Might be a nicer option.
