9-11. Typical Robot Signals
A. Signals Robot Must Have
1. Arc start (referred to as contactor on circuit diagram)
2. Arc detected (current detection)
B. Commonly Used Robot Signals
1. Purge (gas on)
2. Jog forward (motor start)
3. Jog reverse (retract)
4. Wire speed command (wire speed control)
5. Voltage/trim/arc adjust command (depends on selected mode of transfer) Voltage-MIG, Trim-M technology pulse, Arc adjust-Accu-pulse
(basically arc length control)
C. Often Used Robot Signals
1. Standby signal (this means power source is ready to weld)
2. Remote program select (allows robot to change programs)
3. Wire stuck signal (relay closure)
4. Error signal (relay closure)
.
Relays are not used with a digital or Ethernet interface.
D. Seldom Used Robot Signals
1. Touch Sense
2. Water flow error (if using a water flow switch hooked to the power source)
3. Current feedback
4. Voltage feedback
