4.2.4 Connection of voltage detection cable (Voltage detection cable is
used)
This section explains the procedure for connecting the voltage detection cable.
TIPS
• For connection of welding torch, refer also to "4.2.3
-
Connection of welding torch".
1.
Connect the torch cable and the voltage detection adapter to the wire feeder.
2.
Cut the voltage detection cable for base metal side to a suitable length.
3.
Connect the voltage detection cable for base metal side to the base metal.
4.
Connect the voltage detection cable for base metal side to the voltage detection terminal of the wire
feeder.
TIPS
• Voltage detection cable for base metal side can also be connected to the direct voltage
detection terminal for base metal of the welding power source. When using the welding
power source by lifting with hoisting equipment, connect the voltage detection cable for
base metal side to the direct voltage detection terminal for base metal side.
For reducing the influence of inductance noise, take note of the following caution on connection and
wiring example of voltage detection cable.
Connection for voltage detection cable is complete. Procedure is followed by "4.2.7
-
Connection of
shielding gas".
