MEASURING MODE
Select the measuring mode for the part detection.



absolute

measures the way the welding head actually covers.



reference

the distance between both electrodes is determined.

Note: reference

should only be used with part detection.

HEAT
Set a minimum waiting time (heat up time) before an evaluation or a
breakdown is carried out.

Setting range: 0 – 9999 sec.

COOL
Set a minimum waiting time (cool down time) before the displacement value

(S3/S6) is calculated.
Setting range: 0 – 9999 sec.

5.5.2

Configure Part Detection

CHANNEL
Shows the currently selected channel, to which the displacement sensor is

connected. To change the channel click on it.

PART… / DISPLACEMENT…
Switch between part detection and displacement measuring.

ON/OFF
Enables/disables the main function ‘DISTANCE’.

SENSOR

Choose the signal form and the resolution of the displacement sensor
