The Rothenberger Industrial Rolot 611 is a lead-free solder rod designed for general installation and plumbing work. This package contains three 650 g rods made from a Sn91Zn9 solder alloy, each with a diameter of 10.0 mm and a length of 400 mm. The solder has a melting temperature of 199 °C and is suitable for soft soldering tasks such as gutter installation, sheet metal connections, and general installation jobs. This solder alloy is specifically formulated for non-potable water installations and is ideal for working with thin sheet steel and tinning applications. The Rolot 611 offers reliable performance for professional installation work where lead-free solder is required. The solder rods are supplied without flux, so a separate flux application is necessary for optimal soldering results. This product is part of Rothenberger's industrial quality tool range, designed to meet the demands of professional craftsmen in installation technology and metalworking. The solder composition ensures good flow properties and stable joint formation when using appropriate heating devices. The substantial weight of 650 g per rod allows for longer working times between rod changes, enhancing efficiency in larger installation projects. The consistent diameter and uniform length of each rod provide predictable melting behavior and precise application control. This solder is not recommended for drinking water systems due to its specific alloy composition. The product is identified by the model number 1000002362 and represents Rothenberger's commitment to specialized materials in professional craft applications.
