rter phase asynchronous motor and a DC arc welding generator coaxial configuration. AX series DC arc welding machine current regulation has two coarse and fine adjustment. Coarse There are three stop positions, fixed in the lid concave groove, which is moving through the brush holder to achieve. Move along the steering motor brush holder, the operating current is reduced; conversely, the operating current increases. Fine tuning is to change the shunt winding resistance varistor by hand wheel to achieve. AX1 series DC arc welding machine has a current regulating coarse and fine two kinds. Coarse is by changing the line panel series excitation winding turns to achieve. Fine-tuning is changed by the handwheel and realized Reed winding transformer groups resistance. AX3 series DC arc welding machine has a current regulating coarse and fine two kinds. Coarse There are two block from large and small tokens of single-throw switch to achieve. Fine-tuning by hand wheel moving brush to achieve. Polarity change can flip the down, smooth remember number to achieve double-throw switch.
