They are rods, normally 1? The e5543 of a pair of prods are placed on the part and current passed from one prod to the other through the part. They are spring-loaded clamps with braided copper pads on the inside of the jaws.

The clamps are clamped onto the part and a current is passed from one clamp to the other through a part. E5543 are braided copper or lead pads placed at each end 6 of the part.

Current is passed from one pad to the other through the part.

Pads are normally used with stationary equipment and rigged so that the pads are in contact with the part asgm pressure.

Therefore, equipment must be available to transform line current and, when required, to rectify it. The equipment should contain an ammeter to indicate the magnetizing amperage, suitable switches, and, when required, timers to control the length of time that the current is applied. If different amperages are required, the equipment shall produce the maximum required amperage with a suitable control for reducing the amperage to the required lower levels.
