soldering iron allergic to solder
January 11, 2013
Im just starting to make my Start Here Robot, but I'm having real problems soldering.
The solder just will not stick to the soldering iron, or the contacts on my picaxe 28x1. Its so frustrating. I have done soldering before an never had this problem, only difference being that I used to use my Grandads 40 year old soldering iron, and this time I am using a new one that I bought - its pretty cheap and cheerful but it still melts the solder. It just doesnt "flow". The solder is just the stuff that came with the iron, lead free stuff, not rosin cored, but I am using separate flux.
I have cleaned the tip repeatedly with a wet sponge, i am using flux on the tip before I start trying to solder and I am heating up the pins i am soldering, then adding the solder. I cant tin the tip though because the solder just wont stick to it :(
Any help would be really appreciated
