ATTENTIONS & PREVENTATIVE MEASURES
1. Environment
a. The machine works in environment where air conditions are dry with a dampness level of max 90%.
b. Ambient temperature should be between -10 to 40 degrees centigrade.
c. Avoid welding in the rain, to avoid water entering the machine.
d. Avoid welding in dust area or the environment with corrosive gas.
e. Avoid gas welding in the environment with strong airflow.
2. Safety Checkpoint
Our welding machine has a 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. Excessive operation under over voltage, over current or over heat may damage the machine; the
operator must pay attention to the following:
a. The working area is adequately ventilated!
The welding machine is medium and small model. But the running of the machine will also generate high
currents, which natural air flow cannot satisfy its cooling demands. Therefore, each machine has an
internal fan to ensure its stable performance. Make sure the intake is not blocked or covered. There should
be 0.3 metre distance around the welding machine. 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 keep an eye on maximum duty current (compared to the selected duty cycle) to make
sure that the machine working current does not exceed maximum duty cycle current. Over-load current will
damage and even burn the machine.
If machine exceeds standard duty cycle, it may stop working and switch to protection status. The
temperature control switch is activated by over heat released under this circumstance. Meanwhile, the
overheat indicator lights up.
Under this situation, you do not need to pull out the power plug since the internal fan can work to cool down
the machine. When the overheat indicator stops, the temperature has been lowered down to standard
range, operator is
able to starting working again.
c. No over voltage!
Power voltage can be found in diagram of parameters. Automatic compensation circuit of voltage will
assure that welding current keeps is in allowable range. If power voltage is exceeding allowable range
limits, it can damage the components of machine. The operator should understand this situation and take
preventive measures.
