NB Series CO2/MIG/MAG Thyristor Semi-auto Gas Welding Features: 1. High voltage slow feeding device is easy to produce welding arc, stable for welding arc, with small splash, with high quality of welding line, without pore, and without crack. 2. The welding is employed with auto feeding, and is of high efficiency, low heat influence, and low workpiece deformation. 3. It is of function of high accuracy compensation for wave of power line voltage, and stability for output. 4. With F.T. T control circuits, the welding arc is of small ball, and convenient to produce secondary welding arc. 5. We fulfill the consumer requirement for design with functions of weld diameter selection, solid core or medicine core weld selection, welding arc concentration or normal selection, centralization or individual transfer selection. 6. The elements are employed with the brand products, such as relays of Japan OMRON, and welding torch of German BINZEL, which is more reliable at quality, is of multinomial protection functions, and is carefree for the customers.
