Assembling the welding machine
The standard composition of this welding installation consists
of:
• MAXI 405 or 505 generator.
• Earthing cable 4 m long (optional).
Accessories also include front and back wheels for moving
the welder, a chain for fastening the gas cylinder to the cylin-
der trolley easily, a handle especially for moving the machine
around manually, two eyebolts for lifting the machine off the
ground, a pivot to make sure the wire feeder is in the right po-
sition above the machine. Perform the following operations be-
fore using the machine:
• Open the case (box carton) and take out all the accessories
at the back of the welder.
• Mount the back wheels following the description given in
Fig. A.
• Unpack the welder system.
• Check that the welding apparatus is in good condition, other-
wise immediately inform the retailer or distributor.
• Check that all ventilation grilles are open and that no objects
obstruct the free passage of air.
• Lastly mount the handle, pivot and eyebolts following the de-
scription given in Fig. A.
How to lift up the system
Before lifting the unit, open the bag containing the eyebolts (at-
tached to machine), remove the two eyebolts complete with fi-
bre washers and mount them on the upper part of the cover.
IMPORTANT: Only lift the unit using the two eyebolts.
The wire-feeder has a handle and a hook so that it can be
hung up.
NOTE: The lifting and transporting devices conform with Eu-
ropean regulations. Do not use other equipment to lift or trans-
port the feeder.
