may get blocked which could
cause motor damage. If not tightened enough, the
rolls may not be able to feed the wire.
For the
TM 360W, TM 420W, TM 500W, TM
650W
machines, repeat this operation for the sec-
ond knurled knob.
N.B.
When changing the diameter of the wire,
make sure the correct groove of the wire-feed roll
is facing towards the inside of the machine.
To do this, check that the value corresponding to
the wire diameter and wire type being used is leg-
ible (facing towards the outside of the machine).
Remember that the rolls with a “V-shaped” slot
are suitable for feeding iron or steel wires.
Rolls with a “U-shaped” slot are suitable for alu-
minium wires.
Attention:
Before proceeding with the next steps,
make sure the torch cable (
Fig. 3
) is tight and that
no angles or burrs are present on the welding
wire. Please follow these precautions to ensure
the correct operation of the wire guide.
6. CONNECTION BETWEEN THE SEPA-
RATE TROLLEY AND BASE
Before carrying out the operations described in
the following paragraphs, connect the separa-
ble trolley and the machine base for the
TM
360W - TM 420W - TM 500W -TM 650W
machines
.
N.B.
The red and blue tubes (
33 and 34 of Fig
4A
) are only supplied with some machines.
1.
Find the connection side as shown in
Figure 4B.
2.
Connect the power electrical connector (
36 of
Fig 4B
) to the appropriate coupler (
36 of Fig 4C).
3.
