The BX1-650 is a high-capacity, heavy-duty AC arc welding power source designed to meet the rigorous demands of industrial fabrication, construction sites, and repair shops. Utilizing a robust moving-core transformer design, it delivers exceptionally stable alternating current (AC) output, which effectively minimizes arc blow when welding magnetized or thick steel plates. Built with high-grade magnetic steel laminations and premium copper windings, this machine ensures optimal thermal efficiency, a prolonged duty cycle, and minimal power loss. Its stepless current adjustment mechanism allows operators to fine-tune the output precisely to match specific electrode diameters and workpiece requirements. Engineered for longevity and harsh environments, the BX1-650 features forced-air fan cooling and automatic thermal overload protection to prevent overheating during continuous, high-current operations.
