4 . WIRE FEED FOR POWERMIG2750
fig.11
MAKE SURE THAT THE WIRE FEED ROLLERS, THE WIRE GUIDE HOSE
AND THE CONTACT TIP OF THE TORCH MATCH THE DIAMETER AND
TYPE OF WIRE TO BE USED AND ARE FITTED CORRECTLY.
4.1 Loosen the roller pressure adjustment screw and hinge it forwards and
downwards to allow the pressure roller housing to spring upwards
(fig.12a). Ensure that the drive roller is correctly set to drive the wire
diameter chosen (0.6 or 0.8mm). If necessary release and reverse the
roller as shown in fig.12b.
4.2
Straighten about 50-100mm of spool wire (
do not allow wire to uncoil
).
Ensure the wire is undistorted and clean cut with no burrs or sharp
points. Gently push the wire through the plastic guide, over the 6mm
or 8mm drive roller groove and into the torch fitting wire guide by 50 to
100mm. (See fig.12c) Note: Burrs or sharp points at wire tip may
damage the torch liner.

4.3
Ensure that the wire is resting in the groove correctly then close the
pressure roller housing and hinge the adjusting screw upwards to retain
it in place. (See fig.13)
4.4
Set the roller pressure adjustment screw to an intermediate value.(See
fig.14)
3.8
FIT A REEL OF WIRE. Ensure the welder is unplugged from the
mains power.
The machine is supplied with a mini spool of wire, but will
accept up to 15kg spools without modification.
3.8.1 Open the side of the unit, remove any spacer from the reelholder
and push the reel of wire over the holder end springs and onto
the holder ensuring that the spool is rotating anti-clockwise with the wire
drawing off the reel from the bottom towards the wire drive unit. The
larger spools of wire have a guide hole ‘B’ which must be pushed over
the plastic pin located at the back of the reel holder ‘A’ (See fig.10 below).
When a larger reel has been located on this pin, push the appropriate
spacer back onto the holder to keep reel engaged with the pin. The pin,
in conjuction with the braking mechanism will stop large reels from free
wheeling around the holder.
3.8.2 Rotate the reel of wire anticlockwise whilst tightening the adjuster in the
centre of the reel holder until a slight braking pressure can be felt. See
fig.11.
