5 INSTALLATION AND START-UP FOR MIG
WELDING WITH GAS
Position the welding machine so as to allow the free circulation
of air inside and, as much as possible, prevent metal or other
dusts from penetrating.
• The machine must be installed by professional personnel.
• All the connections must be performed in compliance
with applicable standards (IEC/CEI EN 60974-9) and with
accident-prevention laws.
• Make sure the power supply voltage corresponds to the
welding machine rating.
• The protection fuses must be sized according to the details
shown on the technical data plate.
Make sure the earth lead D, inside the reel
compartment, is connected to the negative pole
coming out of the dividing wall.
Alongside the 2 terminals, the polarity is printed in
relief. The positive pole + is that at the top, nearest
to the wire feed motor. The negative pole – is the one
12
lower down, nearest to the earth lead exit.
Connect the earth lead clamp D to the piece to be welded.
Open the side door. Fit the wire reel according to the
instructions provided below.
REEL FITTING SEQUENCE
F
NOTE. During the fitting sequence, the welding machine
must be switched off to prevent the moving motor roller
representing a risk for the operator.
• Fit the reel on the support inside the compartment as
shown in fig. 1.
• The reel must be fitted on the support so the wire
unwinds in an clockwise direction. It is important for
the wire to be stopped on the reel on the visible side,
see fig. 2. Block the reel on the support, as shown in
the illustration.
• Make sure the drive roller is correctly positioned
according to the diameter and type of wire used. To
