The CPVF500 is a next-generation CO₂/MAG welding machine from OTC DAIHEN, utilizing full digital IGBT inverter technology. Its excellent welding performance is achieved through OTC's unique waveform control, which stabilizes the arc and minimizes spatter, with improved arc starting. A new stick welding mode is added for multi-purpose use. Advanced welding condition management stores up to 30 jobs, with 10 directly selectable from the remote control; panel lock and password protection prevent accidental changes. The 100% duty cycle meets high-efficiency demands, and the 1‑knob voltage presetting simplifies operation. Safety features (torch switch protection, automatic gas shutoff) and internal adjustments (arc characteristics, soft arc mode, constant penetration control) make it adaptable to various applications.
