Since it has a screw shape, it takes a long time to attach and detach the chip, and even if the axis is slightly misaligned or the screw forming accuracy is deteriorated, the screw cannot be completely screwed, resulting in poor workability. Furthermore, since the tip and the adapter are screwed together and integrated, there is a problem that it is not possible to perform sufficient cooling, wear occurs in a short time, and it is necessary to frequently replace the tip, There is also a problem in that high-precision screw molding is required and the production cost becomes high.

The drawing shows a contact tip of an electric welding machine used for assembling automobile parts. The tip 1 has a wire feed hole 3 in the center,
This is basically the same as this type of conventional contact tip in that the tip 1 is mounted in the hollow portion 4 of the adapter 2 from the tip side, which is composed of a cylindrical adapter 2.

On the other hand, a tubular portion 7 is extended from the lower portion of the chip 1, and a screw portion 8 that is screwed into the screw portion 5 of the adapter 2 is formed at the base portion of the tubular portion 7. When the chip 1 is screwed and fixed to the adapter 2, a slight gap 9 for cooling is formed between the cylindrical portion 7 and the inner peripheral surface of the adapter. The tip 1 and adapter 2 are
It is preferable to forge with a chromium-copper alloy that is excellent in conductivity and hardness and is inexpensive.

て効率的でローコストの溶接処理が行えることとなる。With such a structure, the welding wire is automatically fed from the wire feed-out hole 3 of the tip 1 and the wire is energized through the tip 1 to arc-weld the object to be welded in a cutoff gas atmosphere. This is basically the same as the conventional contact chip. In the present invention, the threaded portion 8 is formed only on the base portion of the tubular portion 7 extending below the chip 1, and the outer diameter of the other tubular portion 7 is the same as that of the adapter 2.
Since it is slightly smaller than the inner diameter of the tip 1, when the tip 1 is attached or detached, the portion of the tube portion 7 without the screw portion 8 serves as a guide and the tip 1 is easily and smoothly attached to the adapter 2.
Since it can be introduced into the hollow portion 4 and the shaft portion to be inserted into the adapter is not entirely screw-shaped as in the conventional case, the chip can be attached and detached in a short time. In addition, since a slight gap 9 is formed between the tip 1 and the adapter 2, sufficient cooling can be performed, wear does not occur even after long-term use, and tip replacement work is reduced, resulting in improved efficiency. Welding process can be performed at low cost.

It can be used stably for a long period of time, and the production cost can be reduced.
