From Weller this is the WSTA4 Pyropen, a refillable gas-powered soldering iron a unique professional, cordless, versatile piece of soldering equipment plus can be used as a hot air soldering iron. Excellent for use when working in the field as this soldering iron is a lightweight, compact soldering iron and ready to use within 30 seconds. The WSTA4 Pyropen fills with butane gas and we recommend using only the Weller PGR1 butane gas refill, stock number 2161668. When closed the Pyropen soldering iron looks like a standard pen, the top protects the solder tip when not in use and the base of the pen holds the reservoir of butane gas. You do not need to an external ignition source to ignite the soldering iron as it features the Piezo igniter. Replacement hot air soldering nozzles and solder tips are available and the Pyropen is a great addition to any soldering kit.
