speed that varies with changes in arc voltage. When not welding, the display will show what the

wire feed speed will be at the displayed voltage.

Lighting inside the wire feed unit

Lights are fitted inside the cabinet of the wire feed unit. The light located by the wire bobbin turns on

automatically when welding starts or when the left side door is opened. The light is automatically

turned off 4 minutes after welding has stopped or the side door has been closed. The light located by

the feeder mechanism turns on automatically when the left side door is opened and turns off when the

door is closed again. The lights automatically switch on when the feeder is started, when any of the

parameters on the internal control panel are changed, when wire inching is performed and after

welding tasks. The lights automatically switch off after a few minutes.

The bobbin brake force should be increased just enough to prevent wire feed overrun. The actual

brake force required depends on the wire feed speed and the size and weight of the bobbin spool.

Do not overload the bobbin brake. If the brake force is too high, it may overload the motor, resulting in

a lower-quality welding result.

The bobbin brake force is adjusted using the 0.236 in. (6 mm) hexagon Allen screw in the middle of

the brake hub nut.

1) Open the left door of the wire feeder.

2) Untighten and remove the brake hub nut and remove the old wire spool.

3) Insert a new wire spool into the feeder unit and straighten out the new welding wire 3.94–7.87 in.

(10–20 cm). File away burrs and sharp edges from the end of the wire before inserting it into the

feeder mechanism.

4) Lock the wire spool onto the brake hub by tightening the brake hub nut.

5) Thread the wire through the feeder mechanism (according to the illustration on the inside of the

feeder unit).

NOTE!

Replace the brake hub nut and the brake hub sleeve if they are worn out and do not lock

properly.

6) Close and lock the left door of the wire feeder
