Abstract
In an electrode assembly, an electrode holder has a forward end thereof affixed coaxially to an electrode tip. An attachment member is affixed to the holder rearwardly of the electrode. A retaining assembly includes an outer cup component, an inner cup component and a magnet therein. An electrical lead is connected to the inner cup component. The electrode assembly fits coaxially into the retaining assembly with the attachment member adjacent to and retained by the magnet. The electrode holder is seated in electrical contact with the inner cup component. The holder, cup components and attachment member are magnetically permeable, and separated in each assembly by insulators, so as to effect an outer magnetic shielding loop and an inner magnetic shielding loop.
