3.2 INTERNAL CONNECTIONS
• Any intervention carried out inside the welding
machine must be performed by qualified personnel.
• Before working inside the welding machine, make sure
that the plug is disconnected from the power mains.
• After final inspection, the welding machine is con-
nected to the voltage indicated on the power supply
cable.
• To change the supply voltage, remove the right side
panel and arrange the voltage change terminal board
connections as shown in the figure 5.

• The supply voltage may not be changed on single-
phase power sources.
• Do not use the welding machine without its cover or
E
side panels for obvious safety reasons, and to avoid alter-
ing the cooling conditions for internal components.
3.3 EXTERNAL CONNECTIONS
3.3.1 Connecting the mass clip.
• - Connect the earth cable terminal to the socket V of the
welding machine, and connect the earth clamp to the
workpiece.
3.3.2 Cylinder placement and connecting the gas hose
• Position the cylinder on the cylinder holder of the weld-
ing machine, using the straps provided to fasten it to the
rear panel of the machine.
• Periodically check for wear on the straps, and order
replacements if necessary.
• The cylinder must be equipped with a pressure regula-
tor complete with flow gauge.
• Only after positioning the cylinder, connect the outgoing
gas hose from the rear panel of the machine to the pres-
sure regulator.
• Adjust the gas flow to approximately 10/18
liters/minute.
3.3.3 Connecting the wire feeder
This power source accepts the wire feeders Art.1652 and
Art. 1654.
To connect the power source and wire feeder, use the
extension Art. 1182 (5 m) or Art. 1182.20 (10 m).
The performance and operating options of the wire feed-
er are described in the instructions enclosed with the wire
feeder itself.
