An electric wire pressure welding apparatus and pressure welding method capable of exactly specifying the end of an electric wire in a solderless connector and capable of pressure-welding wires from above and below the connector, wherein a wire chuck has a wire holding portion and a pair of wire guide portions projecting from the wire holding portion in a wire-longitudinal direction and having an inner distance larger than a wire diameter for enabling a wire end portion to be disposed between the pair of wire guide portions through which a wire pressure welding blade can go, and wherein the wire guide portions are positioned against a solderless terminal and location of a wire tip is specified by bending the wire end portion about the front end of the wire holding portion in a pressure welding direction by pushing the wire end portion by the wire pressure welding blade. The above wire guide portions on the wire chuck may be replaced with a fixed wire guide extending in the pressure welding direction, wherein the wire is pressure-welded by moving a wire chuck not having the above wire guide portions, in a state of holding the wire, synchronously with the pressure welding blade in the pressure welding direction. |
