Battery welder

Abstract

There is provided a battery welder including: a welding output device to which a welding rod is connected; a welding control device configured to control a welding output by a set welding current value; a battery device configured to supply electric power to the welding output device via the welding control device; and a computation and display device configured to compute a battery condition of the battery device and display a computation result, and including a processor and a display device. The processor calculates a remaining battery capacity based on information acquired the from battery device, calculates a number of welding rods that can be welded based on a welding output for each of welding current values, and causes the display device to display the number of welding rods that can be welded.
