I used the pin soldering iron for awhile. I got good at it so I wanted another one. Well, Harbor Freight moved to town and I got a 140 watt one. I liked that one so much I wanted another one. Well Harbor Freight had a 180 watt one on sale for $6.99. Unless I'm in a tight space, I will use the 180 watt soldering gun. I will try to shoot a video when I solder up my HU.
