SERIOUS DANGER ! 1
NEVER weld in confined spaces (e.g. in a con-
tainer vehicle, a cistern or a storeroom etc.) where toxic, inflamma-
ble or explosive materials are, or have been, located or stored.
Cisterns, in particular, may still contain toxic, flammable or explosi-
ve gases and vapours years after they have been emptied.
SERIOUS DANGER! 3
NEVER use the Welder to melt frozen water
pipes.
SERIOUS DANGER ! 2
NEVER weld a cistern that contains (or has stored)
toxic, inflammable or explosive materials. They could
still contain toxic, flammable or explosive gases and vapours years
after they have been emptied. If you are obliged to weld a cistern,
ALWAYS passivate it by filling it with sand or a similar inert sub-
stance before starting any work.
WELDING ENVIRONMENT VENTILATION
Ventilate the welding environment carefully. Maintain
sufficient air-flow to avoid toxic or explosive gas accumulation.
Welding processes on certain kinds or combinations of metals can
generate toxic fumes. In the event of this happening, use air-sup-
ply respirators. BEFORE welding, read and understand the wel-
ding alloy safety provisions.
GAS TYPES
These welders use only inert (non-flammable) gases for welding
arc protection. It is important that the appropriate type of gas is
chosen for the type of welding being performed.
UNIDENTIFIED GAS CYLINDERS
NEVER use unidentified gas cylinders.
PRESSURE REGULATOR 1
NEVER connect the cylinder directly to the Welder.
Always use a pressure regulator.
PRESSURE REGULATOR 2
Check the regulator is performing its function properly.
Read the regulator instructions carefully.
PRESSURE REGULATOR 3

Check the gas hose is not damaged.
GAS HOSE 2
Always keep the gas hose well away from the work
area.
ELECTRIC SHOCK
Together with the previous instructions, the following pre-
cautions should be strictly observed to reduce the risk of
electric shock
ELECTRIC SHOCK INJURY
DO NOT touch a person suffering from electric shock if
he/she is still in contact with the cables. Switch the mains power
source off immediately THEN provide assistance.
CABLE CONTACT
Do not tamper with power cables if the mains power is still
switched on. Do not touch the welding circuitry. Welding cir-
cuitry is usually low voltage, however, as a precaution, do not tou-
ch the welder electrodes.
CABLE AND PLUG PRECAUTIONS
Check the power supply cable, plug and wall-socket regularly.
This is particularly important if the equipment is relocated often.
REPAIRS
Never attempt to repair the Welder yourself. The result would
not only cause warranty cancellation but also high danger risks.
MAINTENANCE PRECAUTIONS
Always check that the electric power supply has been discon-
nected before performing any of the maintenance opera-
tions listed in this manual ( e.g. before replacing any of the fol-
lowing: worn electrodes, welding wires, the wire feeder etc.)
Never point the welding gun or the electrode towards yourself
or others.
Check no power supply cables, telephone cables or other
electrical items (e.g. computer cables, control lines etc.) are
in the vicinity of the Welder.
Check there are no telephones, televisions, computers or other
transmission devices close to the Welder.
ELECTROMAGNETIC COMPATIBILITY
Make sure that people with pace-makers are not in the imme-
diate vicinity of the Welder.
Do not use the Welder in hospitals or medical environments
(including veterinary surgeries). Make especially sure there
is no electrical medical equipment being used close to whe-
re welding is being done.
Should the Welder interfere with other apparatus, take the fol-
lowing precautionary measures:
1. Check the Welder’s side panels are securely fastened.
2. Shorten the power supply cables.
Place EMC filters between the Welder and the power source. (Con-
tact Fimer Technical Dept. in this respect )

1. MIG WE DING
In MIG welding, a metal electrode consist-
ing of a wire is melted in a weld pool. The
wire electrode is continuously fed by a
welding torch at a constant and controlled
speed. The torch is connected to the posi-
tive pole, while the ground cable is con-
nected to the negative pole. When the wire
is fed and touches the workpiece, an elec-
tric arc is produced. The arc melts the wire
which is then deposited on the workpiece.
MIG welding uses a special metallic wire as
an electrode and an inert gas (CO2,
CO2/Argon mix or pure Argon) to protect
the weld pool. Welding with continuous
feeding of the wire allows using a higher
current density than that used in welding
with coated electrodes. This allows increas-
ing the weld penetration and reducing the
number of passes required to fill the joint.
The welding unit consists of a DC power
source, a wire feeder, a torch and a ground
clamp. Each welder has two switches (13
and 14 of Fig. 1) used to regulate the weld-
ing current (the TM 230 and TM 260 models
only have Switch 13 for this purpose) and
two potentiometers (1 and 9 of Fig. 1) to
respectively regulate the welding time and
wire speed. The welding current and wire
speed must be regulated taking into consid-
eration the thickness of the workpiece to be
welded. Thicker pieces require a higher
welding current and higher wire speed. The
wire speed can be adjusted during welding
to obtain better results.
IMPORTANT: The welding machine must
only be used by trained personnel.
All the TM welding machines are wire
welders produced with advanced technolo-
gy that makes them extremely reliable. In
fact, minimal maintenance is required to
ensure long life of the equipment without
any problems.
The user-friendliness of the welding
machine allows for rapid interchangeability
of operators.
For an excellent welding performance, it is
recommended to use a welding spray. This
will increase the sealing capacity and
reduce weld spatter.
2. POWER SUPP Y CONNECTION
Before connecting the machine, check the
voltage, number of phases and power fre-
quency. The admissible power supply volt-
age is reported in the “Technical
Specifications” section of this manual and
in the machine’s rating label. Make sure
there is sufficient power to run the
machine. The “Technical Specifications”
section of this manual contains information
on the type of line protection devices to
use. The machine comes with a specific
power cord which should not be extended.
If an extension cord is necessary, use one
that has the same or a larger cross section
than the machine’s cord depending on the
length of the cord.
3. OUTPUT CONNECTIONS
The welding cables are connected with a
quick coupling system that uses special con-
nectors. The ground cable must first be con-
nected to its connector (15 or 16 of Fig.1) and
then the torch cable (19 di Fig. 1). This con-
nector also allows connecting the electrical
contacts of the torch and the hose that carries
the welding gas to the torch.
Refer to the following sections for more infor-
mation on the connections to be carried out
before proceeding with the welding.
