NOTES OR PREVENTIVE MEASURES
1.
Environment
1
）
The machine can perform in environment where conditions are dry with a dampness level of max
90%.
2
）
Ambient temperature is between -10 to 40 degrees centigrade.
3
）
Avoid cutting in sunshine or drippings. Do not let water enter the gas.
4
）
Avoid cutting in dust area or the environment with corrosive gas.
5
）
Avoid gas cutting in the environment with strong airflow.

Safety norms
Our cutting machine has installed protection circuit of over voltage, over current and over heat. When
voltage, output current and temperature of machine are exceeding the rate standard, cutting machine
will stop working automatically. Because that will be damage to cutting machine, user must pay
attention to following.
1
）
The working area is adequately ventilated
！
Our cutting machine is powerful machine, when it is being operated, it generated by high currents,
and natural wind can’t be satisfied with machine cool demands. So there is a fan in inter-machine
to cool down machine. Make sure the intake is not in block or covered, it is 0.3 meter from cutting
machine to objects of environment. User should make sure the working area is adequately
ventilated. It is important for the performance and the longevity of the machine.
2
）
Do not over load
！
The operator should remember to watch the max duty current (Response to the selected duty
cycle).Keep cutting current is not exceed max duty cycle current. Over-load current will damage
and burn up machine.
3
）
No over voltage
！
Power voltage can be found in diagram of main technical data. Automatic compensation circuit
of voltage will assure that cutting current keeps in allowable range. If power voltage is exceeding
allowable range limited, it is damaged to components of machine. The operator should
understand this situation and take preventive measures.
4
）
There is a grounding screw behind cutting machine, with a grounding marker on it. Before
operation, cutting crust must be grounded reliable with cable which section is over 6 square
millimeter, in order to prevent from static electricity, and accidents because of electricity leaking.
5
）
If cutting time is exceeded duty cycle limited, cutting machine will stop working for protection.
Because machine is overheated, temperature control switch is on “ON’’ position and the indicator
light is red. In this situation, you don’t have to pull the plug, in order to let the fan cool the machine.
When the indicator light is off, and the temperature goes down to the standard range, it can cut
again.
