Re-useable Electrode Diameter Adapter [Brass Ferrule]
The purpose of the diameter adapter is to make 12 gauge wire fit the flush mounted "Series 2" type electrode sockets.
["Series 1" electrodes for very old models also use this adapter, but were straight and 3 3/8" long....not to be used as a replacement for the longer 'Looped' electrodes. ]
If #12 wire is used un-adapted, bending it while in the socket may destroy the springs inside.
To use: Insert the brass adapter into the socket first, then slide the wire electrode through the adapter till the spring tension inside holds it in place.
10 gauge wire [#10] can be used to make your own electrodes without adaptation, but is sometimes a little too big around.
The end that inserts onto the socket can generally be scraped down with a sharp knife till it fits.
Series 2 Electrodes should be 7” long, total.
They don’t have to be U shaped but will last a lot longer if they are.
To help prevent tip discharge erosion from making “needles” out of straight electrodes, bend the tips slightly away from each other.
.9999 pure solid silver.
Priced per pair.
Series 3 Electrodes are the same as Series 2 but don't use adapters.
