<P>PROBLEM TO BE SOLVED: To easily detect short-circuiting abnormality by using bar code information, in a bar code control style controller for electric welding, and its current-carrying control method. <P>SOLUTION: This controller for electric welding for connecting, by means of current-carrying, an electric welding joint provided with a bar code with a predetermined current rise allowable value appropriate to the electric welding joint recorded in current-carrying control information, and its current-carrying control method are composed. The current rise allowable value is encoded into six sections such as 1=4%, 2=6%, 3=8%, 4=10%, 5=12% and 6=14% by the type and nominal diameter of the joint, and recorded in one of digits as one of maker basis data. <P>COPYRIGHT: (C)2009,JPO&INPIT |
