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 welding in sunshine or drippings. Do not let water enter the gas
4
）
Avoid welding in dust area or the environment with corrosive gas.
5
）
Avoid gas welding in the environment with strong airflow.
2. Safety norms
Our welding machine has installed protection circuit of over voltage, over current and over heat. When
voltage, output current and temperature of machine are exceeding the rated standard, welding
machine will stop working automatically. Because this will be damage to welding machine, user must
pay attention to following.
1
）
The working area is adequately ventilated
！
Our welding machine is powerful machine, when it is being operated, it generated high currents,
and natural wind cannot satisfy with machine cool demands. So there is a fan inside the machine
for its cooling demands. Make sure the intake is not in block or covered, there should be 0.3 meter
distance from welding 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.
WARNING
Blind experiment and careless repair may lead to more problems and make formal check and
repair more difficult. When the machine is electrified, the bared parts contain life-threatening
voltage. Any direct and indirect touch will cause electric shock, and severe electric shock will
lead to death.
NOTICE: In the period of guarantee maintenance, if user makes wrong check and repair for
malfunction of welding/cutting machines without our permission, the free maintenance
guarantee offered will be invalid
