Abstract
Based on variable polarity TIG welding power system platform in the dual inverter has been set up on the power supply,in order to ensure the normal use of the design,the contact type for a variable polarity power supply TIG welding arc,the whole process is divided into short circuit arc stage,arc stage and the current slow rise three stages.The current value and speed of the short stage and the main stage can be changed as needed.The experiments have proved that the arc ignition is suitable for not only the variety polarity source but also can apply on pulse current source,without any obvious tungsten weariness and arc extinguish,and the arc ignition success rate is quite high.关键词
