Initial Instructions / Fault Location - Migatronic FOCUS STICK 160 E PFC Manuel D'instruction

INITIAL INSTRUCTION
Generally
1. Main switch
This switch turns the machine on and off. When the
main switch is switched off, a clicking sound may
appear from the machine whilst the green LED on the
front (6) flashes. This is normal and is not an error.
2. Mains cable
Entry point for mains voltage supply cable
3. Welding cable sockets
DC positive and negative welding current outlet
sockets. Electrode cable to be fitted in positive or
negative outlet socket in conformity with the polarity
of the electrode, and earth return cable to be placed
in remaining socket.
4. Welding current control
This knob is used for adjustment of the welding
current. The welding current is adjustable from 20-
160 A.
5. Overheating
The yellow LED will alight if the machine is
disconnected due to overheating. Overheating arises
if the machine is overloaded. The machine
automatically reconnects when the temperature has
fallen, and the yellow LED will switch off.
Warning:
When the machine is overheated, it is important to
place the electrode holder/torch so as to avoid the
risk of establishing the arc when the machine
reconnects automatically.
6. The green LED is alight when the machine is
switched on
FAULT LOCATION
Repairs must only be carried out by Migatronic staff.
Fault symptoms:
The machine does not work:
There may be no mains supply or the mains fuse is
damaged. Check that both mains supply and mains
fuse are intact.
Check that welding cables are correctly mounted in
the plugs.
Check that the cables are not defective and that
there is sufficient earth connection as close as
possible to the workpiece to be welded.
Overheat:
The yellow LED will alight, if the machine is
overloaded. This occurs
- if welding with a higher load than permitted,
- if the machine requires cleaning, or
- if the air intake and/or outlet of the machine is
completely or partially blocked.
Check that the machine is not overloaded, cf.
"Technical data" and/or clean cooling ribs by use of
clean, dry compressed air after disconnecting the
machine from the incoming mains supply.
The machine does not produce maximum welding
output:
Check the mains voltage being connected to the
machine. Performance depends on correct mains
voltage. Voltage is measured where the machine is
connected to any extension cables.
It may be caused by the fact that the machine is
connected with too long cables, and if possible, only
primary and secondary cables should be reduced as
much as possible.
If rectification of the fault is not possible:
Contact your dealer – the machine may be defective
