General Welding Consumables · Welding Consumables
This radar system operates on the principles of electromagnetic radar, utilizing both X-Band and S-Band frequencies to meet the requirements set by the IMO SOLAS regulations. The L8/S-707 model from Hyundai Welding Co., Ltd. in Pohang is designed to ensure compliance and safety at sea. The radar system is approved by DNV, ensuring it meets stringent maritime standards. Common issues encountered with the device include the end-of-life of the magnetron after 5,000 to 8,000 hours of operation, bearing damage in the antenna rotation motor after 30,000 hours, and backlight failure on the display. Heading marker drift and moisture ingress in the waveguide are also noted issues. To address these, Hyundai recommends keeping a spare magnetron on board for prompt replacement, with a lead time of 1 to 3 weeks. Regular maintenance includes replacing the magnetron within the specified operating hour range, annually lubricating the antenna bearings, and conducting weekly performance monitoring tests as required by IMO regulations. Annual inspections are also recommended to ensure optimal performance and safety.
