Manual magnetic disconnects are a combination of manually and magnetically operated contactors enclosed in a wall-mounted enclosure. The contactors for the disconnect switches are the same as the contactors mill type magnetic controllers.  Silver faced contacts are standard. All external connections to the contactor panel are made on the front of the panel. The incoming line terminals are located at the top and the load terminals are located at the bottom of the contactor-mounting panel. Control circuit wiring connections are made on the side of the panel.

Shielded Metal Arc Welding (SMAW), also known as Manual Metal Arc (MMA) welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode coated in flux to lay the weld. An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric arc between the electrode and the metals to be joined. As the weld is laid, the flux coating of the electrode disintegrates, giving off vapors that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination.
