Description

Single cable for welding machine

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single cable for a welder, and more particularly, to a single cable for a welder connecting a carrier and a welder of a submerged arc welder using a high current.

Submerged Arc Welding is generally used in areas where high strength is required, such as assembling a ship block or a steel frame, the angle of the cabin, the I-shaped ribs, the vertical orientation of the plate, etc., ought.

In this submerged arc welding, molten metal is generated by the arc heat between the base material and the welding rod, and the tip of the welding rod is welded with being buried in the flux.

Here, the arc light generated during welding is shielded by the flux and is not visible from the outside, so the word 'submerged' is used.

1 schematically shows a submerged arc welder.

1, a typical submerged arc welding includes a carriage 10 moving along a rail R, a feed motor 20 feeding a welding wire 21, a carriage 10 mounted on the carriage 10 A sprayer 30 for supplying the flux 31 and a welder 40 for supplying electricity.

Here, the carriage 10 and the feeding motor 20 are connected by a cable.

FIG. 2 is a plan view of a conventional cable for a submerged arc welding machine. As shown in FIG. 2, a conventional welding cable is composed of two welding power lines and one signal and control line.

Such a conventional cable is composed of three wires, so that the wires are sometimes twisted and tangled when moving, and the bulky cable is uncomfortable to hold and store.

Of course, in order to improve this, three wires were wound around with a tape (T), but when used for a long time, the tape (T) was peeled off, making the periphery dirty and damaging the wires.
