With this gun, you can solder up to large diameter landing gear wire. (Save the inside wheel collar and solder on a flat washer instead).
Remember to thoroughly degrease the parts being joined . Alcohol with a clean rag, and a new pipe cleaner dipped in alcohol for inside of parts. Then...scuff up the surfaces with clean, dry sandpaper. Wipe clean again. Be careful how you
handle the parts after cleaning, for the oil from your skin/fingers will compromise joint integrity.
Next is heat. Plenty of it! Heat the parts so that they (the parts) themselves melt the solder. Quick(and careful) wipe of the completed connection with a clean rag followed by a close inspection with a magnifying eyepiece. Go Fly!
