Invention relates to the equipment for pressure welding of tubes with heating by arc controlled by magnetic field, and it can be used in different fields of industry and building, during welding of tubular details of different purpose and configuration, for fulfilling the installation and repair work. Machine for pressure welding of tubes with heating by arc controlled by magnetic field is improved due to the modification of hydraulic cylinders of precipitation, which are executed as the cylinders of double-sided action with one-sided rod. Due to simplification of the mechanism of setting of arched clearance and precipitation high-quality welded joints are made, which considerably facilitate the work of operator and increase the productivity of operation.
