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.
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.
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.
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.
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).
