Abstract
The disclosure relates to the use of metastable state of mixed gases which, when appropriately mixed, provide better control of current and voltage conditions and subsequent arc formation properties in making balls of aluminum, copper and gold with an electronic flame-off method. The specific mixtures involve inert argon mixed with small amounts of hydrogen and neon. Exceptionally well controlled balls of uniform size result.
