Compared with the construction characteristics and function between the t raditional stud welder and invert capcitor discharge stud welder,the main circu it of invert capacitor discharge stud welder,control circuit,discharge circuit and charge circuit are analyzed in detail in this article.

A multi-pulse ignition system based on capacitor discharge was developed,in which,real-time adjustment of the ignition interval and number can be realized.

The ignition of capacitor discharge is a process of oscillation by capacitor discharging to RL circuit set.

On capacitance discharge,voltage drop-time and current-time curves are tested through two electrodes,and the dynamic resistance-input energy relationship of semiconductor bridge is derived.

In order to find out more efficient treatment technology, the removal of medium-low concentration hydrogen sulfide (H_2S) and carbon disulfide (CS_2) from gas stream were studied experimentally with Ultraviolet (UV) photolysis, which is emitted by novel electrodeless lamps powered by microwave discharge or condenser discharge.
