4-2 . Safety requirements

Welding provides protection against overvoltage / overcurrent / overheating. If any 

of the above events occurs, the machine stops automatically. However, over- 

stress damage to the machine , keep the following guidelines :

1. Ventilation . When welding a strong current going through the machine , so the 

machine is not enough natural ventilation for cooling . The need to ensure ad

-

equate cooling, so the distance between the plane and any object around it at 

least 30 cm . Good ventilation is important to normal function and service life of the 

machine.

2. Continuously , the welding current does not exceed the maximum allowable value. 

Current overload may shorten its life or damage to the machine .

3. Surge banned ! Observance of feszültségsáv follow the main parameter table . 

Welding machine automatically compensates for voltage , allowing the voltage 

within permissible limits of law. If input voltages exceed the specified value , dam

-

aged parts of the machine .

4. The machine must be grounded! If you are operating in a standard, grounded AC 

pipeline in the event of grounding is provided automatically . If you have a gen

-

erator or foreign , unfamiliar , non-grounded power supply using the machine , the 

machine is required for grounding connection point földelésvezetékhez to protect 

against electric shock .

5. Suddenly stopping may be during welding when an overload occurs or the ma

-

chine overheats . In this case, do not restart the computer , do not try to work with 

it right away, but do not turn off the power switch , so you can leave in accord

-

ance with the built-in fan to cool the welding machines .

5. Maintenance

1. Remove power unit before maintenance or repair!
2. Ensure that proper grounding!
3. Make sure that the internal gas and electricity connections are perfect and 

tighten, adjust if necessary, if there is oxidation, remove it with sandpaper and then 

reconnect the cable.

4. Hands, hair, loose clothing should be kept away under electric parts, such as wires, 

fan.

5. Regularly dust from the machine clean, dry compressed air, a lot of smoke and pol

-

luted air to clean the machine every day!

6. The gas pressure is correct not to damage components of the machine.
7. If water would be, for example. rain, dry it in the machine and check the insulation 

properly! Only if everything is all right, go after the welding!

8 When not in use for a long time, in the original packaging in a dry place.
