Welding rods in static gap considered bad

["Tesla list" <tesla@xxxxxxxxxx>]

Original poster: "Wim Bosma" <wbosma@xxxxxxxxxxx>

Welding rods in a linear static gap will get quite hot; much hotter than 
copper pipes. It should be tried only with a hefty blower, otherwise spark 
quenching detoriates: after a few seconds the HF output will drop. 
Construction of the spark cage will also be more difficult.
