For example, a fuse with a rated current strength of 16 amperes must be able to withstand 1.25 times this rated current strength (i.e., must withstand 20 amperes) for at least one hour without melting the fusible element. The tripping of the fusible element during an overcurrent condition...
By means of the single welding electrode 1 a molten bath 4 is produced in the workpieces to be welded to each other, which have a thickness of 5 mm, at a current of 300 amperes, which molten bath has relatively large dimensions. [0004] These disadvantages are now avoided in the ...
