However, the hot wire TIG welding apparatus 60 according to the conventional example described above has the following problems. The feed speed of the welding wire 63 is adjusted by the remote controller 6.
Although it is possible to rotate the volume provided in the welding wire 6, the actual feeding speed of the welding wire 63 and the heating current of the welding wire 63 are controlled by the auxiliary power supply 65.
It is necessary to look at the ammeter 73 and the wire feed speed meter 74 provided in the system. There is no problem when performing the welding work near the auxiliary power supply 65, but when performing the welding work away from the auxiliary power supply 65, it is necessary to check the heating current and the feeding speed of the welding wire. Have difficulty. In addition, increase and decrease of the wire supply speed are performed by the remote controller 6.
It was difficult to change the wire speed during the welding operation because the volume in 6 was operated. Such a switch for increasing or decreasing the wire feeding speed can be tentatively incorporated into the wire feeding torch 75. However, since the wire feeding torch 75 is of a pencil type, it is used for inching the welding wire 63. If a push button switch or the like is provided, there is a problem in that, when the push button switch is pressed during operation, the torch swings and the protruding tip of the welding wire 63 touches the work. The present invention has been made in view of such circumstances, and it is possible to confirm a heating current of a wire and a feeding speed of a wire at a welding operation position, and in some cases, change the speed of the wire during the welding operation. It is an object to provide a possible hot wire TIG welding device.

た。
If the feed speed of the welding wire 15 is too high, the feed speed of the welding wire 15 is gradually reduced by pressing the deceleration button 24 of the wire supply torch 14. If the feed speed of the welding wire 15 is too slow, the speed increasing button 23 of the wire feeding torch 14 is used.
By pressing, the feed speed of the welding wire 15 gradually increases. The feeding speed of the welding wire 15 can be confirmed by looking at the wire feeding speed meter 32 of the wire feeding device 13 arranged at hand. Also, the welding wire 15
The heating current is adjusted by adjusting the power coefficient volume 31 of the wire supply device 13 at hand, and the current actually flowing can be confirmed by the heating ammeter 33. As described above, the operator can adjust the feeding speed of the welding wire 15 and the heating current at hand, and can check the actual feeding speed and heating current of the welding wire 15 at hand. Workability has been significantly improved.

The hot wire TIG according to any one of claims 1 to 3.
As is clear from the above description, the welding device is a gun type wire feeding torch, and an operating means for increasing / decreasing the feeding speed of the welding wire is provided on the wire feeding torch. Since the wire feed speed meter for the wire is provided, the actual feed speed can be further confirmed while adjusting the feed speed of the welding wire at hand.
Therefore, workability of hot wire TIG welding can be improved. In particular, a hot wire TI according to claim 2
In the G welding apparatus, a current adjusting means for adjusting the heating current of the welding wire is further provided in the wire supply apparatus, and a heating ammeter for displaying the heating current of the welding wire is provided in the wire supply apparatus. While adjusting
The heating current can be checked at hand. Further, in the hot wire TIG welding apparatus according to the third aspect, the operating means comprises a push button switch, and the push button switch is arranged so as to push the operation button in a direction parallel to the axis of the wire supply torch. Therefore, when the push button switch is operated, the wire supply torch does not run out and the position of the welding wire does not shift.
