This Studio Pro soldering iron is the perfect choice for production, studio, and classroom use. The ¼” chisel tip heats to 750ºF, ideal for foiled or leaded work, and is excellent for working with stained glass projects. The insulated comfort grip stays cool, and the overall lightweight design is ergonomic and easy to handle. The tip comes installed, though it has a knurled nut to hold it in place, so it will be simple to switch tips when needed. Use with a temperature controller if desired. The 100 watt soldering iron has a 1-year warranty. Be sure to use this with a heat-resistant work surface, avoid touching the barrel or tip, and do not cool by dipping in water. Adult supervision highly recommended.
