Can you use a $15.88 Walmart soldering iron to do serious soldering?

In this video I go back to the beginning of my more than 45 years of experience soldering and buy a $15.88 Chinese soldering iron from my local Walmart store and compare it to a Weller PES51 pencil iron connected to my WESD51 soldering station and a Hakko FM-2027 connected to my FM-203.

I have said that you can use the cheapest soldering iron to solder SMD devices like SOIC-8s and QFP-32s. In subsequent videos I will attempt to solder pin headers, a DS1307 real time clock in a SOIC-8 package and a LGT8F328P MCU in a QFP-32 package.

The goal of these videos is to make clear that even beginners can solder modern SMD devices using basic soldering equipment that is readily available locally to most people.
