Weldmatic W65 + W66 4RD Wirefeeder
Model No W65, W66 9
5 Installation
Remote Wirefeeder
The remote wirefeeder is connected to the
Weldmatic power source via the composite
cable interconnecting lead. Check all
connections are firmly made to ensure good
electrical contact, and to prevent gas leaks.
Ensure correct size and type of drive roll is
fitted.
Fitting The Gun and Cable Assembly
The supplied welding 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
The quality of the consumable
wire greatly affects how reliably a
gas metal arc welder will operate.
For best results when welding
mild steel, we recommend quality
WIA AUSTMIG ES6. Dirty, rusty or
kinked wire will not feed smoothly
through the gun cable and will
cause erratic welding. Deposits
from the wire will clog the gun
cable liner requiring it to be
replaced prematurely.
Place the spool of welding wire onto the
spool holder. The location pin should mate
with a hole provided on the wire spool body.
Secure the spool with plastic nut. Check the
adjustment of the spool brake, which should
be set to prevent over run of the wire spool
at the end of a weld, without unduly loading
the wirefeed motor. The braking can be
adjusted by using an allen key to adjust Hex
head bolt inside the hub.
Feeding the Consumable Wire
At the wirefeeder, release the compression
screw and rotate the top roller arms to the
open position. The end of the welding wire can
now be passed through the inlet guide, over
the first lower roller, through the intermediate
guide, over the second lower roller and into
the output wire guide tube. Check that the
drive roll grooves are correct for the wire in
use. The appropriate size is stamped on the
visible side of the installed rollers. Check also
that the correct size contact tip is fitted at
the gun end. Feed roller and tip details are
shown in Section 10 of this manual.
Return the top roller arms to the closed
position and adjust the compression screw
to provide sufficient clamping of the drive
rollers to achieve constant wirefeed. Do not
over tighten.
With the equipment energised, operate the
gun switch to feed wire through the gun cable.
