Edit: using a 25W iron whose tip wasn't heating up properly. Had to use its sides to get the solder to melt, which affected precision.
It's ugly af but it works
I'm a solder soldier
And I'm so sorry for that last part
Now I need to by something that holds everything in place, because what took most time was, well, that.

1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of “discuss” rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This isn't an advice forum
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.
There are a number of content specific communities with subject matter experts who can help you.
Some other communities to consider before posting:
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with “So” - starting a post with pointless phrases, like “I hope this is allowed” or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.
The tip was likely heating up just fine, what you encountered was probably thermodynamics.
Very common for novices to intuitively use the point of the tip. For anything but the smallest joints, it actually is the least effective part of the iron.
Soldering is a game of heat transfer. While you use the iron to transfer heat and try to wet the solder, that thermal energy is being dissipated into the rest of the project - circuit traces, components, and often the heftier ground plane. You’re essentially trying to beat the dissipation rate.
The point of the tip - and especially a conical tip - has a small surface area. Small surface area transfers a small amount of heat. The sides, conversely, have a larger surface area which results in more heat transfer. Most techs gravitate towards chisel or knife tips since they give a wide, flat surface to put into contact with the work.
Ultimately, your circuit works - yay! If you’d like to improve the quality of your joints:
For more stubborn projects, preheating the work with a heat gun can help combat thermal dissipation - just be mindful not to scorch your project!
Thanks for pointing that out! :D Perhaps I should get a chisel shaped tip with the Weller 1010 that I am considering buying.
Fun fact, if you do, get a 2.4mm chisel. That's the most common spacing between pins on multi-pin components, and offers a reasonable amount of surface area. Saves you a LOT of hassle
