Answer / pavan

welding machines are classified based on the type of supply
1.dc welding machine
2. ac welding machine
DC welding machine is further classified into
(1)DCEN direct current electrode negative
(2)DCEP direct current electrode positive
therse DCEN and DCEP are used according to the heat
requirnmrnt on the job area

other classification of dc welding machines is based on the
instruments used
(i)rectifers (ii)transformers
and lot of classification are avaliable

Q : How to calculate cooling water pumps head, do I need to consider static head and frictional loss of the pipe with high elevation? I mean to say is discharge pipe branches to several elevations and joins to the cooling water return line. The highest elevation pipe goes to a heat exchanger at (xx) psi inlet pressure. Should I consider only pump discharge header and this piping for head calculations? How about frictional losses in return pipe? Pressure recovered in return piping is good enough to make it back to the cooling tower?
