一般に溶接機の電撃防止器は溶接棒ホルダ側と
被溶接物側間の無負荷電圧80〜90Vを1.5秒以内
（以下遅動時間という）に遮断し、30V以下にし
なければならない。 Generally, the electric shock protector of a welding machine must cut off the no-load voltage of 80 to 90V between the welding rod holder side and the workpiece within 1.5 seconds (hereinafter referred to as delay time), and reduce it to 30V or less.

いた。 Conventionally, when inspecting or repairing a welding machine, such as measuring the no-load voltage or delay time of a welding machine's electric shock protector, or testing the operation of a remote current adjustment device, it is necessary to check the measurement points and individual measurement instruments. Since segmented measurements were carried out by connecting the terminals with lead wires, malfunctions could occur due to poor contact at the contact parts of the meter or the mounting part of the test element for remote current adjustment, and a large number of preparation tools were required. Therefore, work efficiency was poor, and it took 30 to 40 minutes to inspect one welding machine.

ある。 This invention was made with the above points in mind, and includes a voltmeter connected in parallel to the secondary terminal of the welding machine, a shock protector operation test push button switch,
Since the electric shock protector test circuit is equipped with a stopwatch that is activated when the push button switch is turned on, the no-load voltage and delay voltage of the electric shock protector can be determined by simply connecting this test device and the welding machine using four lead wires. This makes it possible to check the operating time, which improves safety and workability in inspection and repair work of welding machines, and reduces the inspection time per welding machine by 5.
This has the effect of greatly reducing the time required for inspecting and repairing welding machines, such as reducing the time required for inspection and repair work to about a minute.
