Abstract: A system and method of welding is provided where welding power supply has a first output electrically coupled to a welding electrode and a second output electrically coupled to a switching mechanism. The welding power supply provides a welding current through either of the first and second outputs to weld at least one work piece. The switching mechanism has at least a first and second switch position, where the first switch position is coupled to a first position on the at least one work piece and the second switch position is coupled to a second position on the at least one work piece, which is remote from the first position. During welding the switching mechanism switches between the first and second switch positions to change a current path for the welding current during through the at least one work piece.

Abstract: An arc welding method comprising the steps of accelerating a feeding speed of a welding wire to cause shorting between the welding wire and a base metal when a welding end signal is input during a period of arcing, retracting the welding wire backward thereafter until a wire retracting speed reaches a predetermined rate, controlling the wire retracting speed constant at this speed for a predetermined duration of time, then stopping the backward retraction of the welding wire, and then terminating a welding power output after supplying a predetermined amount of welding current for a predetermined duration of time starting from a time when opening of the shorting occurs during the backward retraction of the welding wire.

Abstract: A system and method of starting a welding operation is provided where an electrode is advanced towards a work piece in a pulsed fashion and having a voltage level which will provide a first current when contact between the electrode and the work piece is made. After contact the electrode is retracted so that a welding arc is established and after the welding arc is established the current and wire feed speed is increased to a welding level.

Abstract: A fryer for deep frying a turkey has an outer cooking pot for containing hot oil. A splatter sleeve is telescopically slidable into the pot, the sleeve having a surrounding side wall, an open top surrounded by a top sleeve rim and an open bottom surrounded by a bottom sleeve rim. A lid is sealingly seatable upon the top sleeve rim and has a lid hole. A lid latch latches the lid to the top sleeve rim. A turkey support has a turkey support base, extends upwardly from the base to a handle top end and is insertable through the hole in the lid. When these components and a turkey are assembled, suspended from the handle and lowered into hot cooking oil, the sleeve is sufficiently long that it enters the oil before the turkey thereby assuring a complete splatter barrier.

Abstract: An adjustable food flavoring device with removable smoker box for use in a gas grill is disclosed. The apparatus includes an inverted V-shaped upper plate, an inverted V-shaped lower plate, a feature or features to prevent the movement of the assembly once a user obtains the desired length, a plurality of tabs to keep ceramic briquettes in their desired locations, and a removable smoker box in which to place articles for heating and burning to produce smoke that flavors the food being cooked on the grill.

Abstract: A temperature auto-compensation grill includes rotatingly connected upper and lower grilling units; a heating circuit including a heater and a thermostat having a change-over switch; and an operating mechanism including a linkage that is slidingly connected to the lower grilling unit, a first end of the linkage making contact with the change-over switch and a second end of the linkage extending from the lower grilling unit and making contact with the withstand portion of the upper grilling unit in an open position. The upper grilling unit has a withstand portion withstands that contacts the second end of the linkage and slidingly pushes the linkage when the upper grilling unit rotates from a closed position to an open position. The thermostat has a first steady temperature in the closed position, and a second steady temperature in the open position, and the first steady temperature is lower than the second steady temperature.

Abstract: A lip assembly of a turbojet engine nacelle is equipped with at least one electric de-icing system. The lip assembly includes at least one electric heating member, electrically powered through at least one power conductor. Each power-supply conductor is associated with a neutral conductor or “ground” arranged in a regrouped manner adjacent to a corresponding power-supply conductor.

Abstract: Disclosed is a heat roller control device comprising a high temperature malfunction detection unit configured to receive a temperature value detected by a heat roller temperature sensor; an electrical power control unit configured to cut off, when receiving a high temperature malfunction detection signal, power feeding to a heat roller from an electrical power unit; an analog-to-digital converter configured to periodically convert plural of the temperature values from the heat roller temperature sensor to plural digital temperature values; a temperature value storage unit configured to receive and store the plural digital temperature values from the analog-to-digital converter; a temperature value processing unit configured to read and process the plural digital temperature values stored in the temperature value storage unit; and a high temperature malfunction determination unit configured to receive the processed data, and then based on the processed data, determine whether high temperature malfunction occur
