The system improves the weld beads. The invention provides a means to build the sensor into the wire-feed assembly. The wire, which passes through a liner in the assembly on its way to the weld area, is connected to a pivoting arm which transmits the lateral force to a load cell. The load cell produces an electrical signal proportional to the force. A set screw on the arm preloads the cell to a minimum force while another set screw prevents the force on the cell from exceeding a preset maximum value.
