General Welding Consumables · Welding Consumables
The S-Band and X-Band radar design concept hinges on electromagnetic waves to detect objects at sea. Developed by Hyundai Welding Co., Ltd. (Pohang), the S-7018.G model adheres to strict IMO SOLAS requirements. Regular maintenance is key, with a focus on the magnetron's lifespan of 5,000 to 8,000 operational hours and annual service that includes checking for antenna bearing lubrication and performing weekly performance tests as mandated by the International Maritime Organization (IMO). Keep a spare magnetron handy, given its critical role; replacements typically take between one to three weeks. Antenna rotations are prone to wear after 30,000+ operating hours, while display backlight failures, heading marker drifts, and water intrusion in waveguides due to pressure disturbances can also hamper performance.
