Abstract

In a plasma spraying apparatus comprising a negative part(1)(52), a positive part(2)(42), an insulator(3) connected between the two parts, and a cooling water filler pipe which cools the positive and negative electrodes, the present variable electrode gap type plasma spraying apparatus is characterized by the structure composed of: a rotating handle ring(22) combined on the external supporting bar(16) to move the negative part(1)(52) forward and backward; a rotating connection ring(36) installed to connect mutually the negative part(1)(52) and the insulator(3) with the positive body(2); and a lid(46) on the screw(44) of the positive body(2).
