DEVICE FOR CHANGING ELECTRODE HAVING ENHANCED SAFETY

摘要

The invention relates to a device for changing an electrode of an electrode-carrying tool (2) of a welding device, said electrode-changing device comprising a first portion (12) for housing an electrode-carrying tool (2), said first portion (12) comprising a means for keeping the electrode-carrying tool (2) stationary and a second portion (14) that is mounted around the first portion (12) covering the portion of the electrode (8) that projects outside the first portion (12), the second portion (14) being separatable from the first portion (12) by means of translation along the electrode and being rotatably movable relative to the stationary portion (14) when said second portion surrounds said stationary portion, the second portion (14) comprising a means (33) for clamping onto or unclamping from the mandrel (6) and a means (36) for securing the electrode (8) of the second portion (14), thus enabling the removal of the mandrel (6) when the first portion (12) and second portion (14) separate.
