Attentions and preventive measures
1.Circumstances
1)
The welding operation should be on a relative dry environment.The air humidity should not more than
90%.
2)
The temperature should be during
-10 C to 40 C.
3)
Avoid operating the machine in the rain or sunshine, avoid water entering the machine.
4)
Do not operate machine in dust environment or aggressive gas environment.
5)
Avoid shielding gas welding operation in the environment of strong air flow.
2.Safety
1. Make sure the working area is adequately ventilated .
Welding machine is light and its structure is compact .The electromagnetic fields generated
by the high currents .So natural wind is not satisfy in cooling down components .there is
axial-flow fan in inter-machine in order to force to cool
down it .
2. No over-load !
Limited to welding current strictly according to max allowable current of all kinds
of duty cycles . Do not exceed load working in order to prevent from shorting use
lifetime of welding machine even burning up machine .
3. No over-voltage !
Power voltage of welding machine is listed on the main technical datasheet .With the normal
condition , automatic compensation circuit of voltage may ensure that welding current will not exceed to
allowable volume . If power voltage is exceeded to the allowable volume, that may be damaged to
components. Please more careful .
4 . There is a grounding screw behind machine and marked with ground. Before using, please must be
connected reliably by cable with cross- section is more than 6 square millimeter, which release the static
and prevent the accident happening.
5. If it is over the duty cycle when working, the machine will stop working and enter the state of
protection. On this situation, the overheat temperature control switch would be started and make the
machine stop working. The red light is on at the front panel,but still keep the fan running to make the
machine cooling.when the red light is off,the temperature will be back to the standard range,then it can
work again.
Problems and analysis of cutting
1. The phenomena listed here may be related to the accessories, gas supply, environmental factors and
power supply conditions you use. Please try to improve the use conditions to avoid such situations.
2. Rough cutting surface, poor cutting effect.
A. This kind of situation shows that the performance of the cutting machine has not been
effectively developed. You can check as follows:
a. Confirm that the compressed air source is stable and has enough pressure. Generally, the gas pressure
