Elettro CF Pro MIG 296 Instruction Manual page 7

Any intervention carried out inside the welding
machine must be performed by qualified personnel.
2.2 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
connected to the voltage indicated on the panel
beside 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 picture 3.
• The supply voltage may not be changed on single-
phase power sources.
• Do not use the welding machine without its cover or side
panels for obvious safety reasons, and to avoid altering
the cooling conditions for internal components.
2.3 EXTERNAL CONNECTIONS
2.3.1 Connecting the mass clip.
Connect the earth cable terminal to the socket D of the
welding machine, and connect the earth clamp to the
workpiece.
2.3.2 Cylinder placement and connecting the gas hose
• Position the cylinder on the cylinder holder of the
welding machine, using the chains provided to fasten it
to the rear panel of the machine.
• Periodically check for wear of chains and order
replacements if necessary.
• The cylinder must be equipped with a pressure regulator
complete with flow gauge.
• Only after positioning the cylinder, connect the outgoing
gas hose from the rear panel of the machine to the
pressure regulator.
• Adjust the gas flow to approximately 10/18 liters/minute.
2.3.3 Connecting the wire feeder
This power source accepts the wire feeders WF20, WF40
and, only if it is a SYNERGIC PRO MIG power source,
also the wire feeders WF22 and WF44.
The performance and operating options of the wire feeder
are described in the instructions enclosed with the wire
feeder itself.

4 WELDING
4.1 INSTALLATION
Make sure that the wire diameter corresponds to the
diameter indicated on the wire feeder roller.
Use wire feeder rollers with a "U"-shaped groove for
aluminium wires, and with a "V"-shaped groove for other
wires.
