DM500 Discontinued Professional CO₂/MIG/MAG Welding Machines

OTC DAIHEN DM500 Digital Inverter Welder (Discontinued)

The DM500 was a high-performance digital welding machine from OTC DAIHEN, featuring unique IGBT soft‑switching inverter technology with a main frequency of 80kHz for precise arc control and high efficiency. The new 4‑roll wire feeder with encoder feedback ensured accurate and stable wire feeding. CAN communication enabled easy performance expansion and seamless integration with PCs, robots, and dedicated machines. OTC’s newly developed digital reactor control provided high‑speed stable welding across the entire current range, with a wide selection of arc characteristics to meet various process requirements—excellent arc stability even in all‑position welding. With a 100% duty cycle, it was built for heavy‑duty applications. Although discontinued, its technology has been carried forward in the successor models M500 and P500 (pulse).
