This depends on the size of the nugget required and machine cooling capacity. Most common class two electrodes will work just fine. The best is typically DSC or Dispersion Strengthend Copper.
It could be many reasons. Try turning up the weld tap switch one or two notches or the current by about five percent heat.
Sparks and spatter might be a good thing depending upon the application. For projections or cross wire welding this is normally the case. If there is arcing like noise at the begining of the weld turn up squeeze time five cycles.
Use the highest current and lowest time to make the spot weld. Refer to typical weld parameters charts and tables as the starting point for your specific weld schedule questions.
The best, most complete book is the RWMA manual. (Yes we do sell these.)
The plating is normally a yellow di-chromate coating. If this gets too thick it will be difficult to weld. Higher tap settings should help. Use class two electrode materials next.
Yes.
From initiation to end of hold is normally less than one second. The biggest time is loading and unloading of your parts.
Mid Frequency Direct Current. It is a combination of Transformer and Controller/Timer that uses three phases. AKA Inverter Technology.
Yes but the cost of the equipment is also much more. It might be justifiable when all of the conditions are carefully evaluated.
