Abstract:
A resistance welding apparatus for use in combination with a hand held resistance welder having a translating pressure shaft comprising:a primary mounting arm having an engagement end and a distal end opposite said engagement end; a secondary mounting arm having a first leg substantially normal to a second leg, said second terminating at a second end; means of attachment of said first leg to said hand held resistance welder; means for rotational engagement of said primary mounting arm with said secondary mounting arm at a pivot point; a primary electrode having an attachment end and first contact point; a secondary electrode having an attachment end and having a second contact point having a center axis therethrough; means of attachment of said attachment end of said primary electrode at said distal end of said primary mounting arm; means of attachment of said attachment end of said secondary electrode at said second end of said secondary mounting arm; an electrode connector rotationally engaged at said engagement end of said primary mounting arm; means for cooperative engagement of said electrode connector to a laterally translating shaft on said resistance welder, said translating shaft translatable along a shaft axis between an extended position and a retracted position, said shaft axis being substantially normal to said center axis; means to electrically insulate said primary mounting arm from said secondary mounting arm; said first electrode translatable toward said second electrode to a contact position with said first contact point closest to said second contact point when said when said laterally translating shaft is moved to said extended position; and means to communicate electrical current to said first electrode and said second electrode whereby metal inserted therebetween is spot welded when said laterally translating shaft is moved to said extended position.
