NOTES OR PREVENTIVE MEASURES
1. Environment
1) The machine can perform in environment where conditions are dry with a dampness lever of
max 90%.
2) Ambient temperature is between 10 to 40 degrees centigrade.
3) Avoid welding in sunshine or drippings.
4) Do not use the machine in environment where condition is polluted with conductive dust on
the air or corrosiveness gas on the air.
5) Avoid gas welding in the environment of strong airflow.
2) Safety
norms
The welding machine has installed protection circuit of over voltage and current and heat.
When voltage and output current and temperature of machine are exceeding the rate
standard, welding machine will stop working automatically. Because that will cause
damage to welding machine, user must pay attention to the following.
1)
The working area is adequately ventilated!
The welding machine is powerful machine, when it is being operated, it delivers high currents,
and natural wind will not satisfy machine cooling demands. So there is a fan inside the machine
to cool down machine. Make sure the intake is not in blocked or covered, it is 0.3 meter from
welding machine objects of environment. User should make sure the working area is
adequately ventilated. It is important for the performance and the long life of the machine.
2) Do not over Load!
The operator should remember long life duty cycle of the machine and has to be operated
within the permissible limits & Duty cycle.
Keep welding current is not exceed max duty cycle current.
Over-load current will damage the machine.
3) No over voltage
Power voltage can be found in the technical parameter table Automatic compensation
circuit will ensure
that welding current is
in allowable limit. If power voltage is
exceeding allow weld range it may cause damage to components of machine. The operator
should understand the situation and lake preventive measures.
4) There is a grounding screw behind welding machine, there is grounding marker on it
Mantle must be grounded reliable with cable which section is over 6 square millimeter I
order to prevent from static electricity and leaking.
5) If welding time is exceeded duty cycle limited, welding 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 weld again.
