CONTACT TIP OF GAS SHIELD ARC WELDER

摘要

PURPOSE:To make the stability of feeding to wire and the stability of arc better by constituting to push the wire inside through hole to the wall face of through hole by pusher. CONSTITUTION:A pusher 16 is pushed upward against the spring action of a spring 17 and passes through the tip of wire W since the pusher 16 is pushed by the tip of the wire W when it is inserted into a through hole 13. After the tip of the wire W passed through the pusher 16 presses the wire W by being pushed back with the spring action. The wire W therefore advances in order by electrifying with coming into contact forcibly and strongly by sliding with the wall face of the through hole 13 by the press of the pusher 16. Thus the contact electric resistance is reduced, the feeding stability is improved and the generation of spatters is reduced.
