Review on 🔥 WSTA3 Pyropen: A High-Performance Cordless Soldering Tool for Professionals by Matthew Aiono

Aside from requiring you to have an ignition source (spark or flame) in your tool kit, this thing is made to last. I made sure the butane was empty before loading it into my luggage tool bag. Make sure you pack a note for TSA or your country's travel security agency detailing that you evacuated all the gas or that it could be a gift to someone else! The device had a stable outside temperature. I used it to terminate a submerged cable splice. I think if the TSA doesn't confiscate it, it will travel in my pocket for years. The metal body is a plus, but not shockproof.
