Abstract:
1. A device for removing an electrode from a mandrel of an electrode-holder tool and/or for installing an electrode in the mandrel of an electrode-holder tool, said electrode-holder tool forming part of a welding device, said electrode-holder tool being removed from the welding device before the electrode is removed or installed, said device comprising: a first part configured to house said electrode-holder tool, a part of said electrode protruding at least partly outside of said first part, said first part comprising a device constructed to stop the electrode-holder tool in translation and in rotation; and a second part installed around the first part and being configured to cover said part of the electrode protruding outside the first part, the second part being configured to be separated from the first part by sliding said second part along the electrode and also being configured to rotate relative to the first part when said second part surrounds said first part, the second part comprising a device to tighten or untighten the mandrel of the electrode-holder tool and a device to attach the electrode to the second part to allow it to be removed from the mandrel when the first and second parts are separated, or to permit insertion of the electrode when the first and second parts are installed, said second part being installed around the first part such that, when the electrode-holder tool is disposed within the first part, the electrode penetrates into the device for attaching the electrode of the second part and the mandrel penetrates into the device for tightening or untightening the mandrel.
