at the same spot as the work return lead. To do so, a second
ground clamp, fitted to the protection lead, must be atta-
ched next to the ground clamp of the work return lead.
3.3.3 Connecting the gas hose.
• Keep the cylinders in an upright position by chaining them
to their support.
• Keep the cylinders in a place where they cannot be damaged.
• Do not lift the machine with the cylinder on its support.
• Keep the cylinder away from the welding area and uninsu-
lated electric circuits.
• Cylinders containing inert gas have to be equipped with a
pressure reducer and a flowmeter.
• After having positioned the cylinder, connect the gas hose
that comes out from the rear of machine to the pressure
reducer output.
• Regulate the gas flow to 8¸10 l/min.

5 WELDING
5.1 INSTALLATION AND STARTER
• Machine installation must be done by a competent staff. All
connections must correspond to the rules in force (CEI 20-
10 HD 427) and must respect laws concerning accidents.
• Check that the wire diameter corresponds to that indica-
ted on the roll and mount the wire coil.
• Connect the pipe coming out of the extension with the
cylinder flowmeter.
• Position the welding machine so as to allow free air circu-
lation inside it and avoid that metal or any other.
5.2 THE MACHINE IS READY TO WELD
• Connect the ground terminal to the part to be welded.
• Turn the machine on.
• Extract the conic gas nozzle by rotating it clockwise.
• Unscrew the current nozzle.
• Press the torch trigger to feed the wire until it comes out
from the torch.
WARNING: Keep your face away from the terminal nozzle
while the wire comes out.
