Configuration
MIGATRONIC disclaims all responsibility for
damaged cables and other damages related
to welding with undersized welding torch 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.
Lift instructions
The lifting points must
be used (please see
figure) when lifting
the machine.
The machine must
not be lifted with
mounted gas bottle.
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).

CONNECTION AND OPERATION

Important: stretch out welding hose, earth cable and
interconnecting cable, as necessary, as shown in the figure to
avoid affecting the welding performance and at worst
destructing the welding machine.
Important!
In order to avoid destruction of plugs and
cables, good electric contact is required when
connecting earth cables and intermediary
cables to the machine.
Connection of shielding gas
The shielding gas hose is fitted to the back panel of the power
source (3) and is connected to a gas supply with a pressure
reduction to 2-6 bar. One/two gas cylinders can be mounted on
the bottle carrier on the back of the trolley.
