PURPOSE:To secure the constant pressurizing force cope with the position of a gun and to prevent the generation of defective welding by changing the set pressure of an equalizing cylinder via a pressure variable means according to the inclination of the main body of a welding equipment. CONSTITUTION:The set pressure of an equalizing cylinder 6 is varied by setting the air pressure fed from a pressure control box 10 to the value coped with a positional signal according the inclination of a welding equipment main body 3 at each welding spotting position. With the equipment of this composition the welding coped with a position can be executed and a defective welding can be prevented.
