I use a conical solder tip for through hole soldering too. I use a chisel tip if I have to solder braiding or a large ground plane. I prefer a damp sponge to clean the tip rather than an abrasive scrubber.
For this exercise I clean the tip everytime.Many You Tube videos show guys carrying hot solder around on the dirty tip of their soldering iron.
I'm using a conical tip as well. I am heating the joint not the solder so (I don't see what is wrong). What about the chisel tip for more area?I use 1.6mm conical tips for through hole and 0.8mm tips for SMD. I too prefer using a damp sponge for cleaning the tip.
Concerned that I will accidentally drop solder from tip into joint before its properly heated and have a cold joint.A little solder on the tip before you solder will help bridge the gap between the iron, lead and board. More solder means greater heat mass, more thermal energy transfer. A dry iron just won't do.
Amusing and informative! Thx.
No.Concerned that I will accidentally drop solder from tip into joint before its properly heated and have a cold joint.
If you use sn63/pb37 alloy, you can't make a cold joint. Unlike sn60/pb40 it has no plastic region. It goes from liquid to solid without being susceptible to disruption.Concerned that I will accidentally drop solder from tip into joint before its properly heated and have a cold joint.
Soldering is sort of like many skills. Practice and more practice. Find an old scrap board and take components off and put them back. The more you work at it the better you become.Concerned that I will accidentally drop solder from tip into joint before its properly heated and have a cold joint.
You're only putting a small amount of solder on the tip.Concerned that I will accidentally drop solder from tip into joint before its properly heated and have a cold joint.

Ok. using a soldering iron. I found the toggle mode for C/F and I am working in degrees ~750F. I was at480F and bumped i up to 750F. I am using lead-free 0.7% copper, 99.3% Tin. Am cleaning the iron frequently with a brass sponge and tinning the tip at every session. I am using a chisel tip to increase the area of heat transfer. The tip feels warm 3/4" away from hand but nothing exceptional, maybe it is the tip. My setup was a bundled purchase from Amazon. My soldering station is an YiHUA 862BD+. I have soldered years ago, but in hindsight I was creating cold joints, etc.You're only putting a small amount of solder on the tip.
This thread has over 30 posts and you still haven't given us sufficient information to determine why the solder isn't melting. 480F or 480C? What type of solder? Have you ever soldered anything successfully? Are you actually using a soldering gun?

What do you suggest in place?Put that 99C solder in the bin - dreadful stuff. It's also susceptible to Tin Pest.
If you are not making the product commercially then 60/40 or 63/37 Tin/Lead.What do you suggest in place?
