| Abstract: | The technical and economical significance of developing a touch-arcignition system is put forward. The condition of employing touch-arc-ignition system and some important problems in the designing of the system are discussed in detail. By means of mathematical analysis of its dynamic process,the practicability of the system is proved.At last the degree of the contamination between workpiece and tungstun is analyzed by EPMA. The results of EPMA analysis and practical experiments show that the system developed is more reliable and steadier than high frequency are ignition system. |
