3-14. 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 provide 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.
3-15. Remote Program Select
.
Remote Program Select is factory set to “On”. WaveWriter or File Management software is required to turn this function “Off”.
When Remote Program Select is On, a remote device or robot pendant may be used to select programs. When Off,
program selection must be done from the welding power source front panel.
3-16. Remote Program Setting
.
When Remote Program Select is “On”, program selection will be determined by remote input once a weld is initiated. Prior to welding, program
selection can be done in a normal manner from the welding power source front control panel.
