As a matter of fact there is gold plating on the driver, it makes the solder stick better and resists corrosion :yh:
and it has reverse polarity protection and a hi temp cut off circuit and if you get to close to a raccoon it beeps :crackup:
Got my driver awhile back, forgot to take time to say thanks for a good deal. Awesome packaging!
B.T.W. Nice soldering work! Wish my shaky old fingers could do that clean a job.
Thanks again, you're the best!
