MACHINE PROGRAMME
PI 350/500 AC/DC
PI 350/500 AC/DC is a water-cooled three-
phased welding machine for MMA and TIG
welding. The machine can be delivered both
separately without a trolley or with an integrated
trolley included.
Welding hoses
The machine can be equipped with TIG welding
hoses, electrode holders and return current
cables from the MIGATRONIC programme.
Moreover, we can offer you the following:
Foot control (remember to insert a special
version without jumper inside, dedicated for
water cooled torches)
Handpotmeter (8-pole connector)
IGC (Intelligent Gas Control) kit
Water flow control kit
CWF wire feed unit
CAN remote control
INITIAL OPERATION
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.
Generator use
This welding machine can be used at all mains supplies
providing sine-shaped current and voltage and not exceeding
the approved voltage tolerances stated in the technical data.
Motorised generators observing the above can be used as
mains supply. Consult your supplier of generator prior to
connecting your welding machine. MIGATRONIC recommends
use of a generator with electronic regulator and supply of
minimum 1.5 x the maximum kVA consumption of the welding
machine. The guarantee does not cover damage caused by
incorrect or poor mains supply.
Dispose of the product according to
local standards and regulations.

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.
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).
