Abstract

PURPOSE: To permit the lengthening of cable by reducing the friction of wire inside cable by feeding it at a regularchanging speed without temporary stoppage time when wire for welding is fed through conduit cable.
CONSTITUTION: When wire for welding is inserted into conduit cable, the feeding rate of wire is kept averagely constant while changing it regularly and also approximating temporary stoppage time to almost zero. In this way, the coefficient of friction is lowered and at the same time the contact point is transferred in succession, and also loss due to friction is reduced to increase the feeding capacity of wire. Thus, it is possible to stabilize the feeding wire and also to lengthen the conduit cable by more than 5 m. For example, for a 5 m long conduit cable, wire is fed with a more than 50% average rate of amplitude at frequency of more than 10 KHz and with a temporary stoppage time of a less than 5 m/sec change.
