35 KW Annealing Machine (Without Cooling) adopts a dry-type transformer and is equipped with a pneumatic clamping mechanism. This mechanism can clamp the tube onto the electrodes and make use of low voltage and high-current to create short-circuit with the metal case to heat and anneal the components, which makes preparations for the further bending and shaping of the components. And this machine consists of a clamping control of delay electrifying, an electrifying timing control and a delay power-off control . So it can avoid producing electric arcs between the components and electrodes that will destroy the surface finish quality of the components. This transformer has a series of tap changing which can change the output voltage according to different demands so as to anneal and process components made of copper, aluminum, stainless steel or iron-clad components.
