1.
Check that input power is turned off with the disconnect switch connected to the welding power source.
2.
Remove the attaching screws and open the cover for external connection.
3.
Remove the blind bush and pass the cable through.
●
Process any given blind bush among the several available types.
4.
Connect the cable to the terminal for external connection.
●
Strip the cable cover by 25/64 to 7/16" (10 to 11 mm) from the end while pressing the button on the terminal block
and insert the cable.
●
Fix the cable with cable ties so that no gap may be created between the cable and the blind bush.
5.
Check the wiring and place the cover for external connection back to the welding power source.
4.6 Wiring of Voltage Detection Cable at Base Metal Side
When the extension cable is 99 ft (30 m) or more in length in total, use of the voltage detection cable at the base metal side
is recommended.
The voltage detection cable needs to be wired so that the correct feedback of the arc voltage can be obtained. Connect the
voltage detection cable as near as possible to the base metal to avoid detection of voltage decrease.
Use the voltage detection cable at base metal (optionally available: K5416N00 or K5416G00) by connecting with the wire
feeder or to the voltage direct detection terminal at the base metal side on the front of welding power source.
When using the voltage detection cable, set the internal function F38 to "1". (

•
Ensure to start the operation only after shutting off the input power by the contactor of
the power distribution box connecting the welding power source. Otherwise, electric
shock may occur.
