Welding wire feeding cable

Abstract

Disclosed is a welding wire feeding cable comprising: a ball-type member (110) comprising a ball portion (119) formed on one side thereof, a fastening means (113) provided on the other side thereof, and a through-hole (114) formed through the inner center thereof; a socket-type member (120) comprising a socket portion (126) formed on one side thereof such that a ball portion coupling portion (125)is provided therein, a fastening means (123) provided on the other side thereof, and a through-hole (124) formed through the center of the other side thereof; multiple roller seating grooves providedon one or both selected from the periphery of the through-hole (14) formed through the other side of the ball-type member (110) and the periphery of the through-hole (124) formed through the other side of the socket-type member (120); and multiple rollers (400), wherein, after the rollers (400) are seated on the roller seating grooves, respectively, the ball-type member (110) and the socket-typemember (120) are coupled by the fastening means (113, 123) such that the same constitute cable units (100) as a single unit body, and the ball portion (119) is fitted / coupled to the ball portion coupling portion (125) such that the multiple cable units (100) are successively connected and extend.

Description

technical field [0001] The present invention relates to a welding wire supply cable, and more particularly to a welding wire supply cable capable of supplying soft metal wire such as aluminum to a long distance by adopting a structure that can reduce supply resistance when supplying the welding wire. Background technique [0002] Usually, welding wires with diameters of 0.8, 0.9, 1.0, and 1.2 mm are mainly used for MIG welding and non-MIG welding, and the welding wires are connected by supply cables. From the wire box to the welding gun, the length of the above-mentioned supply cable usually does not exceed 6m. [0003] Since the above-mentioned welding wire is subjected to pipeline resistance when passing through the above-mentioned supply cable, it is not possible to use a long supply cable of 10 m or more. That is, because of the pipeline resistance inside the supply cable, it cannot be supplied at a stable speed, so that there may be a sudden large amount of welding wir...

AI Technical Summary

Problems solved by technology

However, even in the case of using helical springs to form the supply cable, soft metals such as aluminum can still cause supply problems due to excessive resistance

For this reason Teflon tubing is often used when doing aluminum welding, but in this case still suffers from supply resistance and is prone to tearing due to friction, resulting in replacement cycles for supply cables Problem with short wire and wire getting caught in the middle of the supply cable

[0006] Therefore, there will be a problem that the welding quality will deteriorate because the welding wire cannot be discharged uniformly from the welding torch.
