ASSEMBLY
Remove the plastic wrapper then slide the spool
back over the hub, ensuring that it sits snugly,
and replace the collar, spring and plastic knob,
tightening it sufficiently to allow the spool to
rotate smoothly but with a slight amount of
braking friction.
Do not over tighten as this will exert undue
pressure on the wire drive motor and may cause
serious damage.
Threading the Welding Wire (Fig.5)
Loosen the plastic knob (A) by turning it
anticlockwise, (this device maintains pressure on
the wire).
Pull, on the plastic knob, so that the screw rod
hinges out of its slot. This releases the pivoted
pressure roller bracket (C). Raise the bracket
and pull out any wire that has been left in the
wire liner (D), pulling it from the nozzle end of
the hose.

Pull out the end of the wire from the rim of the
spool, taking care NOT to release it. The spool is
wound firmly and should remain this way.
Ensuring the wire is straight and not kinked in
any way, clip off the end cleanly, ensuring there
are no burrs or sharp edges. If it is remove the
end using sharp wire cutters.
Proceed to feed it through the guide tube (E),
over the groove on the roller (B), and into the
wire liner (D), by about 10 - 15 cm (Fig.6).
Reposition the pressure roller bracket (C, Fig.5)
and plastic knob (A, Fig.5) and tighten slightly.
Caution: Tightening the knob too tightly will
crush the wire and damage the wire feed.

Close the side panel of the machine and plug
into a 230-240V, 50HZ outlet. Turn the welder On
using the On/Off switch (Fig.7) then holding the
torch straight out from the welder press the
trigger on the torch (Fig.8). The wire feed roller
will operate feeding the welding wire through the
torch.

Fig 8
Do not point the end of the torch at any part of
your body or face, the welding wire is very sharp
and can cause an injury. When the wire has
emerged from the end of the torch release the
pressure on the trigger, turn the On/Off switch to
the Off position then refit the contact tip and
shroud. Finally trim off any excess wire to 3mm
from the end of the contact tip.
