Review on 🔌 Quad Power Solid State Supply for Improved SEO by Mark Erandio

I bought this Elenco SR3B professional soldering iron because it was only $16 compared to $42 for a Weller WP25 soldering iron. The Weller WP25 and Weller WP35 soldering tips are held in place next to the soldering iron tip by a knurled nut on the end of the soldering iron body. With repeated use, the knurled nut will oxidize and corrode, making it almost impossible to remove. The Elenco SR3B has a knurled nut near the end of the handle, farther from the heating element and away from the soldering iron tip, meaning it's much less sensitive to the heating and cooling of the heating element. The knurled nut on this iron is much less likely to oxidize and corrode than Weller and Ungar soldering irons. Before connecting a new soldering iron for the first time, I always remove the knurled nut and apply anti-seize compound to the knurled nut threads. and tighten the knurled nut again. Then I also apply flux to the tip of the soldering iron before turning it on for the first time. After turning on the soldering iron, I immediately apply solder to the tip and hold it there until it melts so the tip can NOT oxidize. When I'm done soldering, I unplug the connector, quickly wipe it off with a sponge, and add solder to the tip until it cools enough that it can't melt the solder. This prevents the tip from oxidizing as the tip cools. The only downside I can find on this soldering iron is a large metal ring that is attached to the handle with three screws. This ring gets hot and can burn your finger if you touch it. As long as you hold the yellow rubber grommet with your fingers, you won't have any problems. The Weller SL325, SL335 and SL345 also have this metal bushing which keeps the heater close to the handle which can cause burns. The Weller WP25, WP35 and WP45 have a plastic ring that keeps the heater in place and feels cool.
