oops better get back in the right place
Alison....Heliarc is an old generic term for TIG welding from the days when they used helium instead of Argon. The yanks still use the term even though helium hasn't bee used in decades.

A point that struck us was the workmanship.All welds are heliarc
,and done in such a manner as to make a metal shop teacher proud.Gussets are hefty and in al the right places.Here is a double down -tube frame that should be free from breakage,however hard ridden............
That's interesting, I've never seen a "heliarced" AE/Sprite, Frank Hipkin, the Sprite manufacturer told me that the early frames were brazed then they switched to MIG welding for the fastback frame. My frames are both brazed and they're both pre '70 early frames.
