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
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
