Further, the thickness of the outer protection insulating sleeve is consistent with that of the outer tube of the gun neck.

Further, the connecting rod is connected with the cable and fixed through the nut.

The utility model has the advantages that:

1. the utility model discloses well welder shell contains neck outer tube, neck inner tube, neck outer tube inner wall and neck inner tube outer wall fixed connection, and the neck inner tube is connected with the copper main part. Compact structure, welder diameter is little, and welder extension, unique inside and outside union coupling mechanism has guaranteed welder's mechanical rigidity. Robot welding under a plurality of narrow-gap working conditions can be realized.

2. The utility model discloses well rifle neck outer tube and rifle neck inner tube welded fastening guarantee welder's rigidity, and the rifle neck outer tube mainly plays the supporting role, the rifle neck outer tube with copper main part welded fastening is more firm.

3. The utility model discloses well external protection insulating boot thickness is unanimous with rifle neck outer tube thickness, guarantees the uniformity of welder outside surface diameter.
