4-2 . Safety requirements
Welding machine provides protection against over-voltage / over-current / 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 has
not enough ventilation for cooling . Good ventilation is important to normal function and
service life of the machine.
2.
Current overload may shorten life time or damage the machine .
3. Observ the tension range , follow the main parameter table ! Welding machine
automatically compensates voltage , allowing the voltage within permissible limits. If input
voltag exceed the specified value, some parts of the machine can be damage .
4. The machine must be grounded! If you are operating in a standard, grounded AC network
the grounding is provided automatically . If you have a generator or foreign, non-grounded
power supply using the machine, the n the machine requir es grounding connection point to
protect against electric shock .
5. Suddenly stopping may be during welding when an overload occurs or the machine over -
heats . In this case, do not restart the machine , do not try to work with it right away, but do
not turn off the power switch . L eave the built-in fan to cool the welding machine.
5. Maintenance
1. Remove power unit before maintenance or repair!
2. Ensure proper grounding!
3. Make sure that the internal gas and electricity connections are perfect and tight
A djust if
necessary ! I f there is oxidation, remove it with sandpaper and then reconnect the cable.
4. Hands, hair, loose clothing should be kept away from electric parts, such as wires, fan.
5. Regularly clean the machine from dust with dry compressed air .
6 . When the machine is wet , for example from rain, dry the machine and che ck the insulation!
7. When the machine is not in use for a long time, store it in the original packaging in a dry place.
4. Precautions
4-1. Workplace
1. W elding equipment should be kept away from dust, corrosive gas es , flammable liquids.
Working enviroment shall not exceed 90% humidity!
2. Avoid outdoor welding unless protected from direct sunlight, rain and snow . W ork area
tempera ture must be between -10 °C and +40 ° C .
3. P osition the device at least 30 inches away from the wall or any other object .
4. Select a well ventilated area to perform welding.
