PROBLEM TO BE SOLVED: To provide projection welding equipment where components are correctly held to an electrode, and the electrode can be correctly moved to a prescribed part. SOLUTION: An electrode rotary unit 10 is formed by coupling a rotary shaft 55 with a rotary base member 57 provided with a moving electrode 58 and a rotation driving means 56 of rotating the rotary shaft 55. The rotary angle is set in such a manner that a feeding position at which components 1, 84 are fed to a holding part 60 in the moving electrode 58 and a welding position rotated from the feeding position and at which the components 1, 84 are confronted with the mating member 5 are taken. The electrode rotary unit 10 is supported via a moving mechanism 8 of moving to the longitudinal direction and the cross direction and a rotating mechanism 9 coupled to the moving mechanism 8 and changing the direction of the rotary shaft 55.
