OPTIONAL
) (Fig 9)
Fig. 9
If a cooling unit is used, proceed as follows:
• Remove the panel M
• Insert the cooling unit inside the compartment so that
the fluid level inspecting slot can be seen from the front
of the unit.
• Fasten it to the welding machine trolley by means of
provided screws.
3.6 POSITIONINg
Position the welding machine to allow for a free air circu -
lation inside the machine and make sure to prevent intro-
duction of metal powders or any other dust.
3.6.1 Sloping planes.
Since this welding machine is equipped with wheels with -
out brake, do not position it on sloping planes, to prevent
machine tilting or uncontrolled movement.
3.7 START-UP
• Only skilled personnel should install the machine.
• All connections must be carried out in compliance with
current standards (iec/cei en 60974-9) and in full ob-
servance of current safety laws.
• Mount the plug on the power cord, being especially
carefully to connect the yellow/green conductor to the
earth pole.
• Make sure that the supply voltage corresponds to the
rated voltage of the welding machine. In “Multi Voltage”
models, the machine automatically adapts to the sup-
ply voltage of the unit it’s connected to.
• Size the protective fuses based on the data listed on
the technical specifications plate.
