WARNING! BEFORE USING THE WELDING MACHINE READ THE INSTRUCTION MANUAL CAREFULLY! FOR QUALIFIED AND SPECIALLY TRAINED PERSONS ONLY AFTER PROPER READING OF THIS MANUAL IS ALLOWED TO USE AND TO MAINTAIN THIS WELDING MACHINE.

1. Safety operation

• 
  It is highly recommended always to follow the safety rules. Wear protective clothes and special means to avoid injuries to eyes and skins.
  
• 
  Use the welding mask or special protective glasses while working with the welding machine. Only by viewing through the filter lens on the welding mask your eyes are secured by your operation.
  
• 
  Prevent the sparks and spatter from harming your body.
  
• 
  Under no circumstance allow any part of your body to touch the welder's output bipolarity (torch and work piece).
  
• 
  Do not operate under water or more humid place.
  
• 
  Fumes and gases produced when welding are hazardous to health. Make sure to work in places where there are exhaust or ventilation facilities to keep fumes or emissions away from the breathing zone.
  
• 
  Please remember to keep arc rays away from the other nearby people when welding. This is only due to the interference from arc rays.
  
• 
  There will be high temperature when welding work piece, so please don't directly touch on it
  
• 
  No touching on the output connection or any other electrification parts while welding.
  
• 
  No touching on the electrification parts after turning on the power. Cut off the power supply after operation or before leaving the welding site.
  
• 
  No welding in the dangerous site where easily get an electrical shock.
  
• 
  No welding for the container loaded inflammable or explosive materials.
  
• 
  Safe measures should be adoptted while operating in high place to avoid accident.
  
• 
  No entering the welding site for persons not concerned.
  
• 
  Welders possible have electromagnetism and frequency interference, so keep away people with heart pace or the articles which can be interfered by electromagnetism and frequency.
  

• 
  Check the connection of input and output cables and the earth (ground) connection, etc.
  
• 
  Maintenance should be conducted by the trained personnel.
  
• 
  The newly installed machine or the welder not in use for some time needs to be checked by multimeter have the right insulation resistance between each winding and the case.
  
• 
  When the welder is used outdoors, it should be kept from rain or long exposure to the sun.
  
• 
  Check is needed from time to time to make sure the welding cable is in good condition if the welding machine is in frequent use. Check at least once each month if the welder is in regular use. It is necessary to check when the welder is in mobile use.
  
• 
  If the welder is not in use either for a long time or temporarily, it should be kept dry and have good ventilation to free it from moisture, erodible or toxic gas.
  
• 
  Dust removal is needed every year. Check the machine's fasteners, moving-iron, current regulation screws, etc to make sure there are no loose connection problems.
  
• 
  The dust, acid and erodible dirt in the air at the job site can not exceed the amount required by the norm (excluding the emission from the welder).
  
• 
  The welder must be installed in the place where it can not be exposed to sun and rain. Also it must be stored in less humid place with the temperature.
  
• 
  When the machine is operating, the temperature must not be higher than +40°C or lower than -10°C.
  
• 
  There should be 50 cm space about for the welding machine to have good ventilation.
  
• 
  Make sure that there is no metal-like foreign body to enter the welding machine.
  
• 
  Electrode must be taken down from holder when no welding.
  
• 
  No violent vibration in the welder's surrounding area.
  
• 
  Make sure that there is no interference with the surrounding area at the installation site.
