Fitting the Gas Cylinder
Place the gas cylinder on the tray at the
rear of the optional welder trolley (if using).
Retain the cylinder with the chain provided.
Fit the gas regulator to the cylinder. DO NOT
apply grease or oil to these joints.
Fit the end of the gas inlet hose from the
back of the power source to the connector
supplied with the gas regulator, and secure
with the clamp also supplied.
Fitting the Gun and Cable Assembly
The supplied gun/cable assembly
is equipped with a ‘Euro’ wirefeeder
connector which incorporates all required
connection points for welding current,
shielding gas and gun switch control.
To attach the gun/cable assembly to
the wirefeeder mechanism, engage the
mating parts of the male and female Euro
connectors, then rotate the locking ring
clockwise to firmly secure the connection.
Fitting the Consumable Wire
Slide the spool over the retaining tab, locate
the drive pin, and push spool up against the
flange so the retaining tab engages
the spool hub.
Check wire spool rotation tension.
Adjust spool holder wing nut to prevent over
run of the wire spool at the end of a weld,
without unduly loading the wirefeed motor.
Feeding the Consumable Wire
At the wirefeed assembly, release the
compression screw by swivelling it outwards.
This allows the top roller arm to spring to
the open position. The end of the welding
wire can now be passed through the inlet
guide, over the bottom driven roller, and
into the output wire guide tube. Check that
the drive roll groove is correct for the wire
in use. The appropriate size is stamped on
the visible side of the installed roller. Check
also that the correct size contact tip is fitted
at the gun end. Feed roller and tip details
are shown in Section 11 of this manual.
Return the top roller arm to the closed position
and adjust the compression screw to provide
sufficient clamping of the drive roll to achieve
constant wirefeed. Do not over tighten.
With the equipment energised, operate the
gun switch to feed wire through the gun
cable. Holding the trigger for 5 seconds
without welding will allow wire to feed at
maximum speed.
Wire “Inch” - “Load”
When the trigger is pressed the wire will
slowly feed out, until the wire touches the
work piece, then the arc will start and wire
speed will change to selected speed.
If the wire does not touch work piece within
5 seconds, then the wire speed will increase
to maximum to assist wire loading. The wire
speed cannot be adjusted during this time.
