Configuration; Initial Operation - Migatronic FOCUS STICK 160 E PFC Manuel D'instruction

Mains connection
After connection of the mains cable the machine is ready
for use. Please note that all cable connections must be
made by authorized and qualified staff.

The machine will function optimally and satisfactorily if
voltage is kept above permissible minimum voltage.
Warning! There is an imminent danger of damaging the
extension cable if it is coiled during use of the machine,
since the cable will not be cooled sufficiently. The
extention cable must not, at the same time, be used for the
supply of any other equipment.
Connection of welding cables
Connect the welding cables to the front of the machine.
Please note that the plug must be turned through
45 degrees after insertion into the socket. If the plug is not
installed correctly, it will be damaged due to excessive
contact resistance, and as a consequence the machine will
be damaged too. Any extension of welding cables will
reduce the maximum performance of the machine. This is
caused by the fact that the electrical resistance of the
cable will cause a decline in voltage, which is directly
dependent on the length of the cable.

Configuration

MIGATRONIC disclaims all responsibility for damaged
cables and hoses and other damage related to welding
with an 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.

INITIAL OPERATION

Fuse
230V 16A
Usage of the machine
When welding with a FOCUS STICK 160E PFC
machine, some heating of various components of
the machine takes place and during breaks in
welding these components will cool down again.
Mains
It is not possible to overload the machine in
cable
normal use, and the machine can work
continuously at current settings up to 100A during
2
3x2.5mm
MMA electrode welding. If the machine is set for
currents higher than 100A, there will be a need for
periods during which the machine can cool down.
Higher current and higher ambient temperature
will result in longer cooling periods.
The length of the cooling periods depends on the
current setting, and the machine should not be
interrupted during cooling. If the cooling periodes
during use of the machine are not sufficiently long,
the overheating protection will automatically
interrupt the welding process. The yellow LED will
alight and thus indicates that the machine has
been disconnected due to overload. The LED
switches off when the machine has cooled down
sufficiently. The permissible load can be seen
from the paragraph "Technical data".
Example:
60% max. load when MMA welding means that a
cooling period of four minutes after welding for six
minutes is required at a current setting of 120 A;
this calculation presupposes 10 minutes between
the start of each welding period.
The machine has been specially designed for
simple welding jobs and is therefore not intended
to work with high loads over a long period of time.
Mobility
The carrying handle of the machine is strong
enough to be used for movement or carriage,
including lifting by hoist or crane.
During operation the machine must not be carried
around or fixed to a person.
Positioning
Due to its low centre of gravity the machine can
also be placed on tilted bedplates; during its
operation, however, the machine should be
placed in a way that will ensure that pulling of the
welding cables will not cause the machine to tip
over.
It must be made sure that the air intake and outlet
are not blocked, and the machine must not be
placed in a position that will obstruct the
circulation of cooling air.
When used on scaffoldings and the like, the
machine must be fastened properly. The handle
may be used for this purpose.
MIGATRONIC disclaims all responsibility, if the
machine is used for any purpose other than
welding.
