DESCRIPTION OF FUNCTIONS

The MIG-x machine range consists of the following
machines:
MIG 385x S
MIG 445x S
The machines are divided into the following main
modules: power source, wire feed unit, indicator panel
and optional water module.
Power source
The power source consists of a three-phase welding
transformer, two voltage selector switches, a rectifier
and an inductor. The power source has always cooling
with automatic stop. Approx. 4 min after the last
welding the fan stops and starts automatically by a
new welding. The fan will start running when the
internal temperature is above 60
If the power source is equipped with a cooling unit
both this and the fan in the power source will start
running.
Indicator panel
The indicator panel indicates errors and shows
whether the machine is turned on.
Wire feed unit (MWF 8x/MWF11x)
The wire feed unit has always 4-roll drive system
(18m/min). For many welding operations it is
recommended to use 4-roll drive, especially when
welding with fluxcored wire. Furthermore, it is essential
to use wire feed rolls which correspond to the
dimension of the wire and to use torch liners of the
correct diameter and material in the welding torch.
Water module (Option)
The water module consists of a water tank, a
watercooling system and a water pump.

INITIAL OPERATION

Mains connection
The machine must be connected to a three-phase
mains supply and it is important to ensure that the
mains supply voltage is in accordance with the voltage
to which the machine is built. The safety conductor
(earth) is yellow/green.
The machine is equipped with a thermal cut-out
protecting against overload of the machine and
excession of max. current for the mains cable. It is
possible to select the mains fuse so the mains cable is
only protected against short-circuits. The protection
indicated on the type plate of the machine will provide
protection against both overcurrent and short circuits.
Dispose of the product according to local
standards and regulations.

Configuration

MIGATRONIC disclaims all responsibility for damaged
cables and other damages related to welding with
under sized 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.
