NOTES OR PREVENTIVE MEASURES
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.
Our plasma 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,
plasma cutting machine will stop working automatically. Because that will be damage to plasma
cutting machine, user must pay attention to following.
1
） The working area is adequately ventilated
！
Our plasma cutting machine is powerful machine, when it is being operated, it generated by high
currents, and natural wind c
an’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 plasma 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 plasma cutting machine, with a grounding marker on it.
Before operation, cutting crust must be grounded reliable with cable which section is over 6
square millimeters, in order to prevent from static electricity, and accidents because of electricity
leaking.
5
） If cutting time is exceeded duty cycle limited, plasma 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 t
his 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.
