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
(20.1)
and with a
small spanner unscrew and remove the tip
(20.2)
.
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.

the hose barb

on the back.
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

portable take care with additional items i.e. gas bottles
etc.
