Automatic controlling method for welding wire extension
专利汇可以提供Automatic controlling method for welding wire extension专利检索，专利查询，专利分析的服务。并且PURPOSE:To perform titled control at high accuracy irrespective of CP power source and CC power source in controlling method that detects welding current and wire feeding speed by detecting true deviation value of extension. CONSTITUTION:For instance, wire feeding speed W is controlled to make arc voltage constant. An extension controller 13 is constituted centering around a microcomputer, and welding current I that makes wire extension for a specified wire diameter a parameter and speed W characteristic value are stored in a read-only memory ROM. When detected welding current value Id detected by a detector 11 during welding and detected wire feeding speed Wd detected by a detector 8 are inputted, the controller 13 calculates and detects the extension value ld during basing on I-W characteristic value stored in ROM. Then, difference DELTAl between set extension value lr of a setting device 14 and ld is calculated and detected, and a torch 1 is shifted and controlled by a driving controller 15 through a servo-motor 9 and a slider 6 according to DELTAl.，下面是Automatic controlling method for welding wire extension专利的具体信息内容。
