Advantages of welding powder                                                                          

 

1, Current carrying capability from welding point is same as conductor with good conducting performance. After inspection, the DC resistance ratio and change rate
are almost zero before and after welding. This is the level that any of the traditional
welding method cannot be compared

 

2, No need of resources from outside. It can be operated indoor and outdoor

 

3, It won't be damaged by surge current. The test shows the conductor will be melted
earlier than welding points when under high current impact in short period
4, Corrosion or slack will not be produced from welding. As it is weld junction,no
contact surface, no residual stress, junction is stable and reliable as long term
conductive body
5, As it is welding junction, connector and conductor are combined on molecular.So
it has a good mechanical strength and is a permanent junction
6, Equipment is simple, convenient and handy. The operation is easy and can be done
without professionals  







OPERATION INSTRUCTION                                                                                       

 

  Check to ensure the graphite mold and conductor is clean ,no residue before making the connection

 

  Use a propane torch to dry wire conductors and remove remaining cleaning residue, solvent, or water before making the connection.

 

  Close the graphite mold lid before ignition ,and close the lid tightly

 

  Insert the conductors and position them for the connection.Ensure them in the center of cavity.

 

  Keep the irrelevant personnel 1.5M away when welding

 

  Keep the inflammable goods 1-2M away when welding

 

  The operator must be equipped thermal barrier glove

 

  Don't face to the mould opening when welding

 

  The operator keep 1.5M away mould is must after ignition

 

  Don't touch the mould and connected parts directly after welding

 

  Open the mould and take the joint out with wrench 10-20S later after reaction .

 

  Insulate the joint after the conductor cooling completely .
