Abstract: A device for coating printed circuit boards with a fluid coating compound applied to the board surface is disclosed. The device has a conveyor for the printed circuit boards, a sprayer arranged over or under the conveyor, and a covering element on at least one side over an edge area of the printed circuit boards, wherein the area of the covering element covering the edge area of the printed circuit board can be moved away from the printed circuit board. The device also has a wiper, which wipes the coating compound moved away from the printed circuit board off from the covering element and supplies it to a holding tank.

Abstract: The invention relates a method for gas-shielded metal-arc welding during the re-strike during the welding process. It is object of the invention to provide a gas-shielded metal-arc welding method to permit as low an energy intake as possible in the short-circuit phase for the arc welding. According to the invention, this object is solved by a method, characterized in that at the beginning of a short-circuit, a control is activated and remains active for the duration of the short-circuit, which increases an energy intake (phase A) when a characteristic threshold value S1 is fallen short of, and terminates the energy intake when a threshold value S2 is reached, and than lowers the energy intake (phase B).
