How To ensure BSG stator TIG welding quality

To ensure TIG welding quality The previous process such as enamel remove (contorl the remove size should be more than 8mm)cropping need to ensure the stator quality before welding The PLC control welding one slot by slot, 

Question and Answer

1.  About sequence of welding process, Inputs parameters (Like Current, Voltage, Hold time, Etc...)

      and specification,Material handling method (Loading / Unloading mechanism, etc..)

         The welding process is fully automatic, the door is closed during welding process,

       and Loading/Unloading by operator, 

       Other parameter is accoring to actual situation of the stator

 2.    What is the exact purpose of argon gas in this welding machine ?

          How to Join the two copper coils without filler rod ?

          The purpose of argon gas which ejected by welding gun is to protect the stator workpiece,

           as the temperature is very high,
