Why use an acetylene soldering iron instead of propane for roofing?
An acetylene soldering iron burns hotter than propane, helping the copper tip heat quickly and maintain working temperature, particularly in cold weather. This makes the Aero Duplex a strong option for professional roofers who regularly solder gutters, flashing, standing seam details, and other architectural sheet metal.

The Aero Duplex is designed for professional roofing and sheet metal applications involving copper, galvanized steel, and stainless steel. It can be used for soldering roof flashing, gutters, architectural sheet metal, and standing seam roofing details when the proper solder, flux, and surface preparation are used.
