Configuration
MIGATRONIC disclaims all responsibility for damaged
cables and other damages related to welding with
undersized welding
measured by welding specifications e.g. in relation to
permissible load.
Important!
In order to avoid destruction of
plugs and cables, good electric
contact is required
connecting earth cables
intermediary cables to the machine.
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 arising due to
connection of a generator are not included in the
guarantee.
Lift instructions
The lifting points must be
used (please see figure)
when lifting the machine.
The machine must not be
lifted with mounted
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 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.
Connection of torch for MIG/MAG welding
The welding hose assembly is pushed into the central
connector coupling (4) and the nut (5) is tightened by
hand. If a water-cooled torch is used, the cooling hose
is connected to the blue quick-release fitting (7) and
the return hose to the red quick-release fitting (6). The
return lead is connected to the negative pole (8).
Moreover, a multi-plug must be connected on the front
of the machine (9) if the torch is a MIG Manager
Note: MIG Manager
connection kit is mounted in the machine (special
equipment).
