WELDING CONDITION PROGRAMMER OF A MICROCOMPUTER CONTROLLER FOR A RESISTANCE WELDER

摘要

PURPOSE: To set welding conditions with ease without any error and to obtain excellent operability by indicating each control element in terms of a character or symbol and selecting the intended element by lighting the corresponding pilot lamp by seeing the intended control element. CONSTITUTION: A mode selecting switch A selects one of starting systems by stepwise feeding. A switch KLM is a data setting switch, and the operator sets data by pressing said switch while observing the digital pilot lamp in the upper part. A counter 1 is a ring counter which increments at every one push of a mode switch A and returns to 1 upon rising to 4. A counter 2 is used when the element selecting switch is simplified and CWJ are omitted. An encoder is an encoder for coding the element names indicated by the lamps which are lighted when switches BWJ are pushed[JP59153588A]
