Welcome Oxweld.
The old Oxweld torches were sumpin'.
Got a 1920's version that will do .250" aluminum. A manly handful.
Saw an old film of atomic H2 welding -- then passed up an old rig -- no time for non-productive pursuits. Passed up earliest tig machine, too. No time.
Welding aluminum with 1935 victor cut-torch using O/H gives nice results, but the lever is too tempting.
Had I that nice (elusive) flux .... I'd weld Ti .... like the Yak exhausts.
A handful of flame... rod....flux....eyeball shields .... flow it together..... or take lunchbreak ..... just flamebroil some sanddabs..... like the guys at old Ryan Airc.
yeehaw .... got Bialetti pot?
