7.4 CONNECTING TO POWER SUPPLY
Requirements for power network parameters (voltage, permissible range of mains voltage
fluctuations etc.) are given in the table with technical parameters of device and on the rating
plate of cutter.
Before connecting the unit to the power source:
• Check whether the parameters comply with the requirements for unit.
•
Check: mechanical condition of the power cord and plug. The connection status of the power
cord with plug and unit (loose not allowed). If the power cord or plug is damaged or loose
connection is between them, it is forbidden to connect the cutter until fault has been rectified.
• The cutter machine can be connected to the network only when the power socket is properly
grounded.
7.5 CONNECTION OF THE DEVICE
Before connecting the equipment and compressed air to the device, make sure that the unit is
disconnected from the source power and the power switch
6
is in the OFF position.
7.5.1 Connecting the plasma torch
1.
Before connecting the plasma torch, make sure that the control pins in the plug are connec-
ted like in scheme
(see 7.7).
2.
Connect the plug into central socket
4
with due care and caution. Pay particular attention
to the fitting of control pins.
3.
Secure the connection by tightening the lock nut. Check if the connection is tight.
7.5.2 Assembly and connection the compressed air
The compressed air or nitrogen which are used for plasma cutting should be free of contaminants such
as particles, oil and or excessive moisture. For this purpose must be used special compressed air
preparation elements such as: water separator, water filter, solid particles filter, oil filter, oil mist filter, etc.
Use the proper pressure reducer which allows reduction of input pressure to the limit value.
To an appropriate working pressure.
1.
Make sure that the air filtering block is installed properly.
2.
Check the pressure coming out of the compressor or installation. Remember that the pres-
sure cannot be greater than 3.5 – 5bar - the maximum permissible inlet pressure to the filter
block and to the device.
3.
Connect properly the air hose to the input terminal
8
(see 7.3)
.
4.
Make sure that there are no leaks.
5.
The working pressure is adjusted with the device turned on.
6.
The value of working pressure should correspond to the values recommended
(see 6.2)
.
7.5.3 Device connection
1.
Connect properly plasma torch into socket
(see 7.5.1)
.
2.
Connect the compressed air into device
(see 7.5.2.).
3.
Connect return cable into SK socket „+”
3
.
4.
Connect the plasma cutter into power supply
(see 7.4)
.
5.
Turn on the unit by setting power switch
6
in the ON position.
6.
Device is ready to cut.
