HD 500 Industrial Glue Gun

AdTech’s HD 500 utilizes 5/8-inch glue sticks to accomplish its primary mission—to apply long glue lines with maximum output and fewer reloads. When industrial users are required to quickly dispense large volumes of hot melt adhesive, this is the tool they turn to. The 300 watt PTC heating system is capable of providing continuous use, and one pull from the trigger will lay down a 6-foot glue bead—more than triple that of the PRO 200. The HD 500 also boasts the highest glue output—seven pounds per hour—allowing industrial users to spend less time reloading our 5/8-inch sticks, which are twice the weight of the 1/2-inch sticks used by other industrial models. Plus, the tool’s temperature adjustment dial allows users to quickly fine-tune the operating temperature from low-temp (270°F) to ultra high-temp (425°F). Similar to the PRO 200 and HD 350, this versatile glue gun accepts a full range of specialty nozzles to match specific application needs.
