General Welding Consumables · Welding Consumables
This maritime equipment utilizes electromagnetic waves to transmit and receive information, enabling navigation and collision avoidance in various maritime environments. The SC-71LHM Cored / M21, manufactured by Hyundai Welding Co., Ltd. (Pohang), is a reliable X-Band and S-Band radar system compliant with IMO SOLAS regulations. The system's performance is backed by DNV approval. Common operational issues may include magnetron end-of-life after 5,000 to 8,000 operating hours (in magnetron models), antenna bearing motor bearing damage after 30,000+ hours, display backlight failure, heading marker alignment drift, and waveguide moisture intrusion due to pressure issues. To ensure optimal performance, Hyundai Welding Co., Ltd. recommends replacing the magnetron every 5,000 to 8,000 hours, lubricating the antenna bearing annually, conducting weekly performance monitor tests (as per IMO requirements), and scheduling annual inspections. Ship owners should also maintain a spare magnetron on board (for magnetron models), as lead times for replacement parts can range from 1 to 3 weeks.
