摘要： An electrode tip holder, a welding method, and an electrode tip adjusting device. The electrode tip holder comprises a chuck body having an inner diameter hole with a first tapered inner peripheral surface diverging toward the tip thereof, a lock nut threaded with the tip male screw part of the chuck body, and a collet fitted to the inner diameter hole. The collet is axially pressed since the lock nut is threaded with the tip male screw part and reduced in diameter by the elastic deformation of a slit to hold an electrode tip fitted to the inside thereof. The chuck body comprises a coolant supply port supplying a coolant to a groove part and a coolant recovery port recovering the coolant from the groove part which are opened at positions facing the groove part.
