5. INSTALLATION OF THE WELDING
WIRE
Follow the instructions below to install the weld-
ing wire (refer to
Figure 2A
).
Attention: before installing the welding wire,
always remove the gas nozzle (
Fig. 3A
) and
wire-guide tip (
Fig. 3B
) from the welding torch.
1.
Disconnect the power cord from the mains
outlet (
22 of Fig. 2 and 4C
).
2.
Unscrew the knurled knob positioned in the
middle of the welding wire spool (
23 of Fig. 2
)
and, if necessary, remove the used spool.
3.
Remove the plastic wrapper from the new
spool and place the spool on the special spool
holder (
23 of Fig. 2
). Reassemble the knurled
knob. The allen screw
(M8)
positioned under-
neath the knurled knob forms the braking system
of the wire spool. Tighten the allen screw in order
to obtain the best braking result. Too much pres-
sure may cause excessive braking which in turn
may block the wire-feed motor. Too little pressure
may not allow the wire spool to immediately stop
at the end of the welding.
4. TM 230, TM 260:
Unscrew the knob of the
wire-feed unit (
27 of Fig.2A
) and lift the upper
feed roll (
29 of Fig. 2A
).
TM 300, TM 350:
Unscrew the knob of the wire-
feed unit (
27 of Fig.2A
) and turn outwards. This
will lift the upper feed rolls (
29 of Fig. 2A
).
TM 360W, TM 420W, TM 500W, TM 650W:
Unscrew the knobs of the wire-feed unit and turn.
This will lift the upper feed roll (
29 of Fig. 2A
)
Remove any wire left over from the previous
welding.
5.
Insert the wire into the little in-feed tube
(26 di
Fig. 2A)
of the wire-feed motor and let it slide
under the wire-feed rolls.
6.
Lower the upper rolls
(29 of Fig. 2A)
and tight-
en the plastic knob
(27 of Fig. 2A)
of the wire
pressure regulator.
Tighten slightly. If tightened too much, the wire
