USE
WIRE FEEDER CONNECTED WITH REMOTE
CONTROL CONNECTOR
Wire feeder connection
Connect the wire feeder to the welder with the
welder turned off:
-Welding cable between the machine's (9) welding
plug (+) and the wire feeder.
-Welding cable between the machine's (10) welding
plug (-) and the piece to be welded.
-Control/power cable between the machine's
connector (X1) and the corresponding connector
on the wire feeder.
Start the machine welder
The "ON" LED will be off and will turn on only when
there is voltage at the welding plugs (and therefore
at the wire).
The voltage is only present when the welding torch
button is pressed.
The setting of the welding voltage is done using the
knob on the wire feeder.
The adjusting knob on the welder is automatically
inhibited.
WELDING DIGITAL CONTROL
WARNING
You can use the wire feeder only by respecting
the pin configuration as shown on the below
mentioned table.
