A weld gun including a frame structure, a weld arm mounted on the frame structure,
an electrode mounted on the weld arm and including an electrode cap at one end
of the electrode, a transformer, and a shunt fixedly secured at one end thereof
to another end of the electrode and fixedly secured at another end thereof to the
transformer. The electrode is elongated and defines a longitudinal axis, the shunt
end of the electrode defines a shunt mounting surface that is oblique with respect
to the longitudinal electrode axis, and the electrode end of the shunt defines
a mounting surface adapted to seat on the mounting surface of the electrode and
operative when so seated to position the end portion of the shunt defining the
electrode end of the shunt obliquely with respect to the longitudinal axis of the
electrode whereby to reduce the total angular curvature of the shunt between the
weld arm and the transformer and thereby reduce the stress and strain in the shunt
produced by repeated operation of the weld gun with consequent longer shunt life.
