ことが防止される。When the cylinder 12 is contracted from this state,
Both tip dressers D1 and D2 approach each other, and each welding tip T is cut by coming into contact with the cutting blade 22 through the opening 201. At this time, for example, if the cutting blade 22 of the first tip dresser D1 comes into contact with one of the welding tips T first, as the cylinder 12 contracts, only the second tip dresser D2 approaches the first tip dresser D1. The cutting edge 22 of the second tip dresser D2 contacts the other welding tip T with a slight time delay. In this way, the pair of welding tips T are connected to the corresponding first and second tip dressers D1 and D2, respectively.
Cutting is performed by contacting the cutting edge 22 of 2 with uniform pressure. The load that the cutting blade 22 receives due to the contact of the welding tip T is absorbed by the elastic deformation of the buffer member 26 that supports the back of the cutting blade 22, thereby preventing excessive load from being applied to the cutting blade 22. .

Moreover,
Even if the welding gun inserted between both tip dressers is roughly positioned, the cutting edges of both tip dressers can be brought into contact with the corresponding welding tips with equal pressure, so the welding tips can be placed evenly. Cutting becomes possible.

This makes it possible to improve cutting accuracy and durability of the cutting edge.
