4.3 Welding environment and safety
Environment
a) The machine can perform in environment where conditions are dry with a dampness level
of max 90%.
b) Ambient temperature is between -10 to 40 degrees centigrade.
c)
Avoid welding in sunshine or drippings. Do not let water enter the gas
d) Avoid welding in dust area or the environment with corrosive gas.
e) Avoid gas welding in the environment with strong airflow.
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 rate
standard, welding machine will stop working automatically. Because that will be damage to
welding machine, user must pay attention to following.
a)
The working area is adequately ventilated
Our welding 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 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.
b) Do not over load
The operator should remember to watch the max duty current (Response to the selected
duty cycle).Keep welding current is not exceed max duty cycle current. Over-load current
will damage and burn up machine.
c) No over voltage
Power voltage can be found in diagram of main technical data. Automatic compensation
circuit of voltage will assure that welding 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.
d) There is a grounding screw behind welding machine, with a grounding marker on it. Before
operation, welding 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.
