3. INSTALLATION OF THE MACHINE
Before use
Several checks are necessary before using the unit to ensure good performance of the machine:
-
Check the electrical line voltage: it should be between
200V and 240V
, 3 phases, with a
40A delayed circuit breaker,
curve D (or aM type
fuse).
-
Check the cross section of the cable going from the main electrical board to the socket where the machine will be plugged in
to: it should be
4x10 mm
2
(AWG8). If the cable is longer than 10m, use a 10mm² conductor. If you are using an electrical
extension
cord, use a 6mm² conductor (use 10mm² if the total length of the electrical line + extension cord is greater than 10m).
-
Connect a
3 phase plug with earth
(minimum 40A) to the power cable.
-
In case of bad connection or bad voltage on the electrical line, the following screen will appear :
On the right hand side of the screen appears the voltage on each phase.
Overvoltage : the mains voltage lies beyond 268 V rms.
Low voltage : the mains voltage lies below 160 V rms.
Unbalanced phase : one phase has a significantly lower voltage than the
other two.
Missing phase : one phase is not connected properly.
-
Caution: in order to avoid voltage drops which can generate bad welding spots, do not overload the electricity supply, do not
use cables with insufficient diameter/cross seciton. Do not use a mains socket that is located too far from the circuit breaker.
-
If the machine is not sufficiently powered, it will not be possible to ensure a good quality weld.
-
Check that the
compressed air
network can deliver a
minimum of 7 bars
(dry air), then connect the compressed air
network to the back of the machine.
The machine must not be used on a compressed air network with a pressure lower to 3 bars.
