Abstract: An apparatus used in removing an electrode tip from the tip end of a welding tool, such as a welding gun, including a main body having a vibration block which is repeatedly hit by a hammer at a rate of, for example, 3,600 times a minute. The vibration block is provided with a tip end holding hole which receives the tip end of the welding tool. When the welding tool with the tip end in the tip end holding hole is vibrated by the hammer which is vibrated by pressured air, the electrode chip is vibrated and removed from the welding tool by the vibration. The removed tip can stay in the tip end holding hole after being removed, thus being prevented from flying out of the vibration block.
