Initial Operation - Migatronic PI 320 DC Manuel D'instruction

Mains connection
Before connecting the power source to the mains
supply, ensure that the power source is of the same
voltage as the mains voltage provided and that the
fuse in the mains supply is of the correct size. The
mains cable (1) of the power source must be
connected to the correct three-phase alternating
current (AC) supply of 50 Hz or 60 Hz and with earth
connection. The sequence of the phases is not of
significance. The power source is switched on with the
mains switch (2).
Lifting instructions
The lifting point must be used as shown in the
following drawing. The machine must not be lifted with
a mounted gas bottle!
Configuration
MIGATRONIC disclaims all responsibility for damaged
cables and other damages related to welding with
undersized welding torches and welding cables
measured by welding specifications e.g. in relation to
permissible load.
Warning
Connection to generators can damage the welding
machine.
When connected to a welding machine, generators
can produce large voltage pulses, which can damage
the welding machine. Use only frequency and voltage
stable generators of the asynchronous type.
Defects on the welding machine arisen due to
connection of a generator are not included in the
guarantee.
Important!
In order to avoid damage to plugs and
cables, good electric contact is required
when connecting the work return cable
and welding torch to the machine.
Dispose of the product according to local
standards and regulations.

INITIAL OPERATION

PI 320/400/500
PI 350
Gas connection
Connect the gas hose (3) to the gas system by means
of a gas pressure reducer with flow control. Fit and
secure the gas hose to the gas connection (4) on the
front of the machine.
Connection of welding cables
Connect the welding cables and the return current
cable to the front of the machine.
Please note that the plug must be turned 45 degrees
after insertion into the socket - otherwise the plug can
be damaged due to excessive contact resistance.
Always connect the TIG torch in the minus (-) socket
(5) and the return current cable in the plus (+) socket
(6).
