2.4.3 Safety Precautions for Electricity Use
Make sure that voltage of all equipment meets the requirements of the machine, and that the power cord and the circuit
breaker are securely connected so as to avoid damage to the equipment caused by lack phase.
The shell of each equipment must be grounded to avoid damage to electrical components of the equipment caused by static,
and to avoid injury to the operator caused by circuit failure and electric leakage.
When replacing electrical components, cut off power, and wait for a period of time before operation. Live-wire work is
strictly prohibited. Regularly remove dust on the circuit breaker, transformer and wiring board to prevent current from
breaking through dust, which may cause damage to the equipment.
Turn off the industrial control computer first and then turn off the main power supply after the work is completed.
2.5 Connection to Gas Circuit
Two air pipes extend from the lathe bed. One is used to connect nitrogen (compressed air or nitrogen is used while cutting),
and the other is used to connect oxygen. Connect the nitrogen pipe to the nitrogen supply unit through the nitrogen gauge,
and connect the oxygen pipe to the oxygen supply unit through the oxygen gauge.
Refer to the schematic diagram of gas circuit in the standard file for details.
Refer to the requirements in the running materials for gas specification.
Attention points of gas circuit installation
1) Gas purity may affect the speed and effect of cutting, and high-purity gas may bring high speed and better effect.
2) For different countries or regions have different standards, our standard configuration of nitrogen and oxygen gauges may
be unable to connect to your gas supply device; under such situations, please purchase nitrogen and oxygen gauges
separately in the local market.
3) The temperature of the supplied gas should be not over 50℃;
4) In principle, it is recommended to keep in contact with gas suppliers in the issues of gas supply;
5) If gas source is farther away, it is strictly prohibited to lay down gas pipes and cable in the same pipeline, and gas pipes
are separately connected to the joint of the machine tool;
