I already had a gas soldering iron that works fine without electronic ignition. I bought this one because it had precisely this type of handy ignition. Ignition works fine by against the transfer of heat to the failure to is very bad: is it of the heater or metal failure I do not know? What I see by cons is that it is difficult to weld with this iron: the solder melts and flows with the wrong part or component to be welded.
