5. INSTALLATION
WARNING! ALL
ELECTRICAL CONNECTIONS MUST ALWAYS BE CARRIED
OUT WITH THE WELDING MACHINE SWITCHED OFF AND
DISCONNECTED FROM THE POWER SUPPLY.
THE ELECTRIC CONNECTIONS MUST ONLY BE CARRIED OUT BY
EXPERT OR QUALIFIED TECHNICIANS.
ASSEMBLY (180A and 220A versions)
Unpack the welding machine, assemble the separate parts contained in
the package.
Assembling the return cable-clamp
Assembling the welding cable-electrode-holder clamp
POSITIONING THE WELDING MACHINE
Choose the place where the welding machine is to be installed so that
there are no obstructions to the cooling air inlets and outlets; at the same
time make sure that conductive dust, corrosive vapours, humidity etc.
INSTALLATION OPERATIONS

cannot be drawn into the machine.
Leave at least 250 mm of free space all around the welding machine.
WARNING! Position the welding machine on a level surface
with sufficient load-bearing capacity, so that it cannot be
tipped over or shift dangerously.
CONNECTION TO THE MAIN POWER SUPPLY
- Before making any electrical connection, check the rating plate data on
the welding machine to make sure they correspond to the voltage and
frequency of the available power supply where the machine is to be
installed.
- The welding machine must be connected only and exclusively to a
power supply with the neutral conductor connected to earth.
- To guarantee protection against indirect contact use the following
types of residual current devices:
- A type (
- In order to satisfy the requirements of the EN 61000-3-11 (Flicker)
standard we recommend connecting the welding machine to the
interface points of the main power supply that have an impedance of
less than Zmax = 0.2 ohm.
- The IEC/EN 61000-3-12 Standard does not apply to the welding
machine.
If the welding machine is connected to an electrical grid, the installer
or user must make sure that the machine can indeed be connected (if
necessary, consult the company that manages the electrical grid).
Plug and outlet
Connect the power supply plug to a mains socket fitted with fuses or an
automatic circuit-breaker; the corresponding earth terminal should be
connected to the (yellow-green) earth conductor of the power supply.
Table 1 (TAB. 1) shows the recommended delayed fuse sizes, in amps, for
the main supply, which have been chosen according to the maximum
rated current output from the welding machine, and to the nominal
power supply voltage.
WARNING! Non-compliance with the above regulations
renders the manufacturer's safety system (class I)
inefficient, with resulting serious risks to people (e.g.
electric shock) and things (e.g. fire).
WELDING CIRCUIT CONNECTIONS
WARNING! BEFORE CARRYING OUT THE FOLLOWING
CONNECTIONS MAKE SURE THAT THE WELDING MACHINE
IS SWITCHED OFF AND DISCONNECTED FROM THE POWER
SUPPLY.
Table 1 (TAB. 1) shows the recommended sizes of the welding cables
(in mm ), according to the maximum current output from the welding
2
machine.
Furthermore:
- Fully rotate the welding cable connectors in the fast coupling (if
present), to guarantee perfect electrical contact; on the contrary, the
connectors will overheat causing their rapid wear and loss of efficiency.
- Use welding cables that are as short as possible.
- Do not use metal structures that are not part of the workpiece, when
replacing the welding current return cable; this can endanger safety
and give unsatisfactory cleaning results.
AND WELDING CIRCUIT CONNECTIONS IN MIG-MAG MODE
Connecting to the gas bottle (if used)
- The gas bottle that can be positioned on the trolley supporting surface:
max 30kg.
- Gas bottle can be loaded on welding machine bottle support platform:
max 30kg (for 180A version only).
- Screw the pressure reducer(*) onto the gas bottle, inserting the
appropriate adapter supplied as an accessory when Argon or an Argon/
CO mixture is used.
2
- Connect the gas input hose to the reducer and tighten the clamp.
- Loosen the adjustment ring nut on the pressure reducing valve before
opening the gas bottle valve.
(*) Accessory to be purchased separately if not supplied with the product.
Connecting the welding current return cable
Must be connected to the workpiece or to the metal bench on which it is
positioned, keeping it as close as possible to the joint being done.
Torch
Prepare the torch when loading the wire for the first time, by dismantling
the nozzle and the contact tip, to ease its exit.
