Welding filler metal wire feeding flexible dual inner cable for MIG welding machine

摘要

The present invention relates to an induction pipe having a double inner tube structure in an induction pipe for welding seam supply of a MIG welder, and its purpose is very high in the process of the seam being released from a container or bobbin containing the seam and reaching a welding torch of the MIG welder. Strong and flexible to ensure safe passage between weld line bobbin to weld line feeder for smooth supply, weld line passes continuously while welding line passes smoothly to improve smooth supply characteristics and service life of guide pipe. The inner tube that has less wear due to friction and the inner tube which has strength and flexible elasticity to protect the function of the inner tube and provide a smooth passage and improve the service life. To provide an induction tube composed of. In the construction of the present invention is a cross-sectional configuration of the guide pipe surrounding the welding seam for MIG welding, it consists of a welding line from the center, the inner inner tube and the inner inner tube surrounding it, consisting of a reinforcement portion and a covering portion It is done.
