Further, when the operation of the liquid coating unit 29 is explained with reference to FIG. 4, the torch 40 is located above the spray cylinder 30 as shown by the solid line, and then descends so that the tip of the shield nozzle 41 is the proximity sensor 31. When passing through the annular portion of the FRL unit 33, the solenoid valve 32 is opened by the output of the proximity sensor 31, and the compressed air input from the tube 34, together with the anti-spray liquid in the lubricator of the FRL unit 33, the tube 35, the solenoid valve 32, When the spray is ejected from the tip of the spray cylinder 30 through the tube 36 and the shield nozzle 41 reaches the position described by the one-point chain line, the torch 40 rises, the spatter adhesion preventive liquid is applied to the inside of the shield nozzle 41, and the shield nozzle When the tip of 41 comes off from the annular portion of the proximity sensor 31, the solenoid valve 32 closes and the ejection of the spatter adhesion preventive liquid stops.

The frequency of operation of each part differs depending on the welding condition environment and welding conditions. For example, the cutter part 17 cuts the welding wire 18 for each welding, and the cleaner part 1 removes spatter every 20 times of welding. When the spatter adhesion prevention liquid is applied once a day at the liquid coating unit 29, the welding wire 18 is cut at the cutter unit 17 at the end of welding on that day, the spatter is removed at the cleaner unit, and the liquid is applied. The spatter adhesion preventive liquid is applied in the part 29 to prepare for the next day's work.

As described above, according to the present invention, the cleaner portion 1 with the sensor 14 for detecting the spatter adhering to the shield nozzle 41 and the shield nozzle 14 for cutting the tip of the welding wire 18 are provided. It consists of a cutter unit 17 with a sensor 26 to detect, a liquid application unit 29 with a sensor 31 for applying a spatter adhesion prevention liquid to the shield nozzle 41 and detecting the shield nozzle 41, and a substrate 15, and is equipped with a sensor 14. A second mounting plate in which the cleaner portion 1 is mounted inside the first mounting plate 16 mounted vertically to one end of the board 15, and the cutter portion 17 with the sensor 26 is mounted vertically to the other end of the board 15. A liquid application portion 29 with a sensor 31 attached to the outside of the 27 and further attached to the inside of the fourth mounting plate 38 vertically attached to the rear of the substrate 15 with the sensor 31 attached to the rear of the cleaner portion 1 to the substrate. Since it is attached to 15, each operation can be performed in the shortest route by a simple configuration, an appropriate amount of spatter adhesion preventive liquid can be applied, and the solidified ball of the welding wire 18 can be cut. It has the effect of being able to do it.
