Abstract
Items constituting a resistance welding schedule are set to desired numerical values by pressing three kinds of keys, namely a shift key for designating one item after another, and increment and decrement keys for setting or changing a numerical value corresponding to each designated item. Each item is displayed in an individual display section of a display unit, with the display sections being made to blink sequentially as each corresponding item is designated. The numerical values are displayed directly item by item and are set sequentially as the respective items of the schedule are designated.
