General Welding Consumables · Welding Consumables
This maritime equipment falls under the radar system category, essential for navigation and collision avoidance. The SW-5NiLT / C1 model, manufactured by Hyundai Welding Co., Ltd. (Pohang), complies with IMO SOLAS regulations and operates on both X-Band and S-Band frequencies. This radar system uses electromagnetic waves and is DNV-approved. Common issues reported include magnetron end-of-life after 5,000 to 8,000 hours of operation, bearing damage in the antenna rotation motor after 30,000 hours, backlight failure in the display, heading marker misalignment, and moisture ingress in the waveguide due to compromised pressure sealing. For maintenance, it is recommended to keep a spare magnetron on board, as the lead time for replacement is 1 to 3 weeks. The magnetron should be replaced every 5,000 to 8,000 hours of operation, and the antenna bearing should be lubricated annually. Weekly performance monitoring tests are required by IMO regulations, and an annual inspection is necessary to ensure proper functioning.
