Wireretract; Gasblow; Touchsensortoolsel; Touchsensoron - Kemppi A3 Integration Manual

5.1.8 WireRetract

This signal function feeds the welding wire backwards.
The wire is fed at the speed of 1.0 m/min for 3 seconds
and then stepped to 5.0 m/min.
• 0 = Wire retract off
• 1 = Wire retract on
This signal has no effect during welding or simulated
welding.

5.1.9 GasBlow

This signal function opens the shielding gas valve. The gas
valve can be controlled during welding, but not during
simulated welding.
• 0 = Gas valve closed
• 1 = Gas valve open

5.1.10 TouchSensorToolSel

This signal function sets the selection of the touch sensing
tool between the welding wire and the gas nozzle.
• 0 = Welding wire as touch sensing tool
• 1 = Gas nozzle as touch sensing tool

5.1.11 TouchSensorOn

This signal function sets the touch sensor power source
and the touch detection device to be on. The touch voltage
depends on the configuration. For more information, see
A3 MIG Welder Operating manual.
• 0 = Touch sensor off
• 1 = Touch sensor on
This signal has no effect during welding or simulated
welding.

5.1.12 OnlineControl

This signal function enables robot-controlled values for
welding wire feed speed, voltage, and fine tuning. When
the robot is in online mode and uses the WireFeedSpeed,
Voltage, and FineTuning
sponding values in the active memory channel are over-
ridden. When the robot is in offline mode, it gives full con-
trol to the welding system and the values from the active
memory channel are used.
• 0 = Robot in offline mode. The wire feed speed,
voltage, and fine-tuning values are obtained from
the active memory channel.
• 1 = Robot in online mode and controlling the
wire feed speed, voltage, and fine tuning.

5.1.13 Watchdog

This signal function resets a watchdog timer in the robot
interface unit on each transition. The signal takes effect
when the watchdog function is turned on from the DIP
switches. If the watchdog functionality is on and the robot
can't maintain transitioning of this signal, the welding
system goes into an error state. This prevents welding
accidents if the robot loses control over the welding
system.

5.1.14 ErrorReset

This signal function resets the
Error
there are no active errors in the system. If there are any
active errors, the signal has no effect. The error is active
control functions, the corre- when the error situation is not yet resolved.
