Checking
1. Make sure the machine is properly grounded!
2. Make sure that all connections are perfect, especially grounding of the machine!
3. Check that the electrode cable connection to be perfect!
4. Make sure that the polarity is correct outputs!
5. Welding spatter can cause a fire, so make sure there are no flammable materials
the work area!

Operation
1. Turn on the main power switch! The LCD display shows the current value and the fan
starts rotating.
2. Adjust welding parameters for welding in accordance with the value specified for
practical application.
3. Usually the welding current is formed in accordance with the electrode diameters as
follows. Make sure that it is current with reserve your unit has, otherwise do not even
try to get the job done!
