CIRCUIT OF CURRENT DETECTION FOR ARC SENSING SYSTEM

摘要

In industrial welding robot system in that the welding torch performs the seam tracking through the left and right weaving, the welding torch is controlled accurately by detecting the current flowing the welding torch. When the direct power source is supplied to the welding torch (4) and the material (5) through the reactor (2), the current induced in the current detector (3) is applied to the sample- and-hole circuit (10).
