INSTALLATION – PRODUCT OPERATION
Only qualified personnel authorized by the manufacturer should perform the installation of the welding equipment. During set up,
the operator must ensure that the machine is not connected to the mains.
Risk of harm caused by mobile elements !
The wire feeders contain moving parts that may catch hands, hair, clothes or tools which can lead to injuries! Take extra care.
• Do not touch pivoting or mobile parts or parts used for the feeding parts !
• Make sure that all panels remain closed when in use !
GENERAL DESCRIPTION
AUTOFEED 450 is a mobile MIG/MAG/Open-Arc wire feed case. The plastic casing makes it naturally electrically insulated and it also has the IP23
pro-tection rating meaning it is protected against water projections and external elements. It powers itself by using the voltage available on the
welding circuit. This voltage can come from a current source (CC), a voltage source (CV), an alternative signal, a positive direct signal or negative
direct signal. AUTOFEED 450 pilots the arrival of the gas, the welding current and wire feeding. The welding current, welding voltage, wire feeding
speed and power supply voltage are displayed.
The powerful wire feed motor assembly has 4 drive rolls and is suitable for standard and cored/flux wire up to 2.4mm thick..

CONNECTIONS AND RECOMMENDATIONS
Make sure the welding generator is switched off when connecting or disconnecting the wire feeder.
The unit is powered by connecting the power cable in the case to a welding generator. You must choose the polarity based on the type of wire used.
The welding cable potential will be the same as the welding torch.
Connect the second polarity of the generator to the piece to weld.
