A pinch type weld gun wherein a shunt is fixedly secured at one end thereof to a gun electrode and fixedly secured at another end thereof to the gun transformer. The shunt is formed of a plurality of elongated strips of flexible copper material which are arranged in stacked configuration whereafter the end portions of the stack are electrically welded to fuse the end portions together to form solid unified end portions. The strips are unsecured intermediate the unified end portions to form a flexible intermediate portion extending between the transformer and the electrode. The solid end portion of the shunt for securement to the transformer is thereafter machined to form intersecting longitudinal and transverse bores to define a passage for delivery of a coolant fluid to the transformer coolant passage system through the solid end of the shunt.
