Product description

Without changing the terminal voltage of the arc welding generator, the product can obtain the external characteristics required by the arc power supply by connecting the rheostat into the welding circuit. The rheostat can adjust the welding current in sections. By connecting the knife switch and the arc welding machine circuit, the required specification welding current value can be achieved through the combination / superposition of the knife switch. For example, when testing 200A, close the knife switch of 100A and 100A (200a = 100A + 100a), and its resistance element is a customized alloy wide flat belt wound on the resistance skeleton, It is connected to the knife switch base and terminal post of the panel through the conductive row.
