2.1.7 Connection of Voltage detecting cable (workpiece side)
(for WB-M350L/WB-P350L/WB-P400L/WB-P500L)
To fully utilize the welding performance when the wire material is a steel or SUS, it is difficult to
wire the voltage detecting cable in such a manner to ensure accurate feedback of the arc voltage.
INFO.
Connect the voltage detecting cable (torch side) to the connector of the upper
arm. For installation procedure, please refer to the instruction manual “Welding
Torch for Robot” and “Coaxial Power Cable for Robot”.
Connection of Voltage detecting cable (workpiece side)
(1) Connecting the voltage detecting cable (workpiece side)
Connect voltage detection cable (workpiece side) to a place near to workpiece as possible.
Wire the torch (voltage detecting wire) to along with the voltage detecting cable (workpiece
side) as much as possible and lower the shaded area Figure 2.1.8.
Connect the voltage
detecting cable in such
a manner to minimize
the shaded area.
Figure 2.1.8 Routing of the Voltage Detecting Cable (workpiece side)
(2) In case of plural welding stages
Connect the workpiece cable to each stage subsequently, and then connect the voltage detecting
cable (workpiece side) to the stage which was connected at last (so as to avoid detection of
voltage drop occurring in the workpiece cable).
