ABSTRACT:
The process and apparatus according to the present invention includes positioning the tab portion(s) of a particular electrode grid and the connector portion of a terminal connector in working proximity to an arc welding apparatus, activating the torch and varying a magnetic field around the torch "flame" to alter the angular orientation of the "flame" relative to the torch tip for moving the "flame" in a generally elliptical pattern. As preferably embodied, a variable electromagnetic field is generated around the torch "flame" by at least four electromagnet probes positioned in oppositely disposed pairs around the torch which is a plasma arc welding apparatus. According to another aspect of the invention, the cell core is positioned adjacent the torch by moving the cell core towards the torch in a direction parallel to the longitudinal axis of the torch "flame".
