Setting the wire feed pressure

Illustration A

Start by making sure that the wire moves smoothly through the wire guide. Then set the pressure of

the wire feeder's pressure rollers. It is important that the pressure is not too high.

To check that the feed pressure is set correctly, you can feed out the wire against an insulated

object, e.g. a piece of wood.

When you hold the welding torch approximately 5 mm (0.2 in.) from the piece of wood (illustration

A), the feed rollers should slip.

If you hold the welding torch approximately 50 mm (2 in.) from the piece of wood, the wire should

be fed out and bend (Illustration B).

The wire reel hub incorporates a friction brake which is adjusted during manufacture for optimum

braking. If it is considered necessary, adjustment can be made by turning the thumb screw inside the

open end of the hub clockwise to tighten the brake. Correct adjustment will result in the wire reel

circumference continuing no further than 1/8 in.-3/16 in. (3-5 mm) after release of the trigger. The

electrode wire should be slack without becoming dislodged from wire spool.

CAUTION!

Overtension of the brake will cause rapid wear of mechanical wire feeder parts, overheating of

electrical components and possibly more incidences of contact tip burnback.

5.7

One dual groove feed roller is supplied as standard. Change the feed roller to match the filler metal

wire diameter.

1) Open the spool side door.

2) Release the pressure roller arm by levering the tension screw.

3) Lift the pressure roller arm.

4) Remove the feed roll retaining screw by turning it counterclockwise.

5) Change the feed roll.

6) Tighten the feed roll retaining screw by turning it clockwise.

7) Secure the pressure roller arm and wire drive tension screw.

8) Close the spool side door.

NOTE!

Visual indication on the face of the drive roll indicates the diameter of the groove on the

outside of the drive roll and the groove that is in use for the selected wire diameter.
