INITIAL OPERATION
Mains connection
The machine must be connected to a mains supply
and protection earthing. After the mains plug (1) has
been connected to the mains the machine is ready for
use. Please note that all cable connections must be
made by authorised and qualified staff. Switch on and
off the machine by means of the breaker (2) on the
rear of the machine.
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.
Connection of welding cables
The electrode holder and return current cable are
connected to plus tap (3) and minus tap (4). Observe
the instructions from the electrode supplier when
selecting polarity.
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.
