3. Fit the wire spool so that it feeds off the base of the
reel towards the wire drive unit (18).
4. Pull tensioner (18.1) forward off the tension arm
(18.2), the tension arm (18.2) will spring up out of the
way.

5. The wire must sit in the appropriate groove for the
wire gauge. The groove size is etched on the side of
the roller. Remove nut to see the groove size that is
NOT in use. The drive roller (18.4) can be removed
from shaft, to change the groove size for appropriate
wire gauge. Unscrew and remove the retaining cap.
6. Pass the filler wire through the guide (18.3) and over
the top of the drive roller, make sure the wire is well
inside the torch liner before closing the arm (18.2)
and tensioner (18.1).

9. Press the feed trigger on gun and observe the wire
feed mechanism. If the wire is being fed correctly it
will come out of the swan neck. If it jams you will
need to remove the gas shroud (9.1) and with a
small spanner unscrew and remove the tip (9.2).
Pass the tip over the wire and secure back onto the
swan neck. Do not over tighten. Resecure the gas
shroud and trim the wire back as required.
Note: Ensure the tip size matches the wire size prior to
installing.

7.5 NO GAS WELDING PRINCIPLE
For a successful weld joint, the molten metal must be
protected from contaminating gases found in the air.
This is achieved by using a flux cored filler wire. The flux
is produced as the wire melts.
The flux creates a coating over the weld and once
cooled will need to be removed by chipping it off.
If allowed to cool naturally some areas of the flux may
ping off of the weld by themselves due to thermal
contraction for this reason it is recommended that eye
protection is worn
