Provide your customers with on-the-spot soldering for jump rings on charm bracelets and chains with this unique machine! Developed by Rio Grande for a leading chain-store company, the Hot Spot® is the perfect tool for serving your customers' jewelry needs while they wait, keeping profits from walking out the door. Hot Spot is the ideal choice for fast, easy, jump ring soldering in your store! Use solder-filled jump rings for a cleaner and easier application. Compact, solid-state unit takes up very little bench space. Specifically designed to permanently fuse solder-filled jump rings (not suitable for other standard soldering jobs). The electrical current that runs through the charged graphite electrode heats the solder core so it flows into the jump ring seam, leaving less to clean up. Extremely localized, adjustable heat won't damage most stones.
