WARNING!
Danger due to welding processes starting unexpectedly if the Error reset signal is
always active and the Welding start signal is set at the same time.
This can result in severe personal injury and damage to property.
▶
Ensure that the Welding start signal is not set during troubleshooting if the Error
reset signal is active at the same time.
Additional information for TWIN systems:
The signal resets the error on both power sources.
Touch sensing
(TouchSensing) -
Single Bit
WARNING!
Danger from electrical current. When Touch sensing is activated, a voltage of
approx. 70 V (up to 3 A) is applied to the wire electrode/gas nozzle.
May result in serious injuries or death.
▶
Do not touch the wire electrode and the torch body (gas nozzle, contact tip) when
Touch sensing is active.
▶
When Teach mode is active, do not touch any electrically conductive parts that are
touched by the wire electrode and the torch body (gas nozzle, contact tip, etc.).
The Touch sensing signal can be used to detect contact between the wire electrode or
the gas nozzle and the workpiece = short circuit between workpiece and wire electrode
or gas nozzle.
-
If the Touch sensing signal is set, the control panel of the power source displays
touch and a voltage of approx. 70 V (current limited to 3 A) is applied to the wire
electrode/the gas nozzle.
-
If a short circuit occurs, this is reported to the robot controller by the Arc stable sig-
nal / Touch signal (see page
) and Touch signal (see page
).
-
The output of the Arc stable / Touch signals (see page
) and Touch signal (see
page
) lasts 0.3 seconds longer than the duration of the short circuit current.
-
As long as the Welding start signal is set, the Touch sensing signal cannot be activ-
ated.
-
The welding process can also be started if the TouchSensing signal is active. This
automatically deactivates the touch function.
-
TouchSensing can be activated independently of the operating mode (internal para-
meter selection, special 2-step mode characteristics, Job Mode, etc.).
