8-7. Touch Sensor Operation
The touch sensor feature allows the robot to locate a weldment using the wire feed system and welding power source. The weld output terminals pro-
vide a path for touch sensor voltage when this feature is turned on at the peripheral receptacle. Turning on touch sensor causes a DC voltage to be
present on the welding wire. When welding wire touches the weldment, the voltage sensing circuit closes, and a +24 volts DC output signal is sent to the
robot control indicating weldment detection. Touch sensor DC voltage on the welding wire is 80 volts DC. As soon as touch sensor turns on, WIRE LIVE
appears on the front panel display.
