CONNECTION AND OPERATION
Permissible installation
The following sections describe how the machine is made ready
for use and then connected to mains supply, gas supply etc. The
numbers in parentheses refer to the illustrations in this paragraph
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).
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.
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 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 max. 6 bar. One gas cylinder can be mounted on the
bottle carrier on the back of a trolley if any.
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. The return lead
is connected to the negative pole (6).
Torch adjustment (Dialog torch)
The current size can be adjusted both from the machine and the
welding torch if a welding hose with dialog torch is in use. This
function cannot be disconnected. The torch adjustment is passive
without Dialog torch.
Inching
The function is used for wire inching e.g. after change of wire.
Wire inching starts by pressing the green key pad and
simultaneously triggering the torch trigger. Wire inching continues
even though the green key pad has been released. It does not
stop until the torch trigger has been released again.
