In general, the automatic (auto, machine) or semi-auto welding method in carriage welding such as pipe orbital joint welding is different from general covered arc welding that is discontinuous using a single rod (electrode). It is very efficient because it continuously performs welding work using the welding wire supplied semi-automatically or automatically.

The welding wire is supplied to the welding torch through the welding wire feeder so that a smooth welding operation can be performed, and the welding wire is smoothly supplied to the welding torch during welding so that the welding wire can be smoothly supplied to the end of the welding wire at the same speed as the supplied speed. A welding tip for supplying a welding wire while maintaining the speed is coupled.

However, when welding is performed using a conventional welding torch, the wire is supplied as it is wound on the welding rod spool along the liner, and the wire is delivered with a high cast and helix ratio. There was a problem in that the supply of the welding wire was not performed properly due to kinking during the supply process or local concentrated frictional resistance due to eccentricity of the liner. And since the work must be stopped in order to remove the twisted welding wire, there is a problem that the welding work takes a lot of time. In addition, there is a problem in that the welding wire, which is twisted during the supply of the welding wire, is disposed of after removal, so that the material cost for welding is high.

In addition, since the welding wire is wound on the spool of the welding wire feeder, uneven wear occurs inside the welding tip according to the cast ratio of the welding wire, and the probability of occurrence of defects increases when used for a long time, bending greater than the cast ratio When this occurs, there is a problem that the welding wire is cut.

In addition, when the liner is disposed on a straight line with the welding torch to reduce the cast ratio of the welding wire, the size of the equipment increases, thereby limiting the space, and the cast ratio occurs according to the location of the welding torch, so the fundamental problem is solved couldn't
