[Also in Group XXII] In a resistance seam welding machine current from the transformer secondary winding 30 travels to a pervious conductive layer, e.g. a braid sleeve 38 on the end of contact-arm 33, and then via contact roller 17 to one side of seam 11 in the workpiece 10, from which it returns to the transformer by a similar path on the other side of the seam. Liquid for cooling the interface between pervious conductive sleeve 38 and contact roller 17 is fed via pipe 34 in arm 33 to a radial passage 37 opening into groove 36 on the semi-circular inner surface of arcuate portion 35 of the arm. Hub 17a of contact roller 17 carried on insulated shaft 23 is of slightly smaller radius than this semi-circular surface so that groove 36 in arm 33 may be covered with the pervious copper braid sleeve 38 through which the cooling liquid seeps to the interface.
