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.
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 rated standard, welding machine will
stop working automatically. Because that will be damaged to welding machine, user must pay attention
as following.
1)
The working area is adequately ventilated
The welding machine is powerful machine, when it is being operated, it generated by high currents,
and natural wind will not satisfy 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.
2)
Do not over load
The operator should remember to watch the max duty current (Response to the selected duty
cycle). Keep welding current do 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 welding current keep in allowable rangement. If power voltage is exceeding
allowable rangement limited, it is damaged to components of machine. The operator should
understand the situation and take 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 in 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.
