The CPVS500 is a classic thyristor-controlled CO₂/MAG welding machine from OTC DAIHEN, renowned for its stability and reliability. The 1‑knob voltage presetting function automatically matches arc voltage to the welding current, greatly simplifying parameter adjustment. The intuitive control panel makes operation easy even for beginners. Stable arc starting from low to high currents ensures smooth welding. Suitable for mild steel and stainless steel, the CPVS500 is a cost-effective choice for general fabrication.
1‑knob voltage presetting — Arc voltage automatically matches welding current, reducing manual adjustments and improving efficiency.
Easy operation — Welding conditions can be set easily on the front panel; user-friendly interface.
