Damn! motherfucker just going to fuse the wires together directly

Contactless solder

u/Pyrhan 13d ago

*Solderless solder.

(AKA "welding")

53

u/yegor3219 13d ago

The tip itself is the solder, obviously.

24

u/TheArmoredKitten 13d ago

There's also brazing. Brazing rod isn't technically solder.

6

u/Astecheee 12d ago

What's the difference?

20

u/lostempireh 12d ago

Brazing is a higher temperature process, it requires more powerful heating equipment, but leads to higher strength joints. In the case of copper. Silver alloys are used for brazing, while tin (or historically lead) alloys are more typically used for soldering.

11

u/Remnie 11d ago

And cadmium! Because brazing should be fun for everyone in the area, not just you. (Cadmium is almost never used anymore these days)

u/Kaneshadow 11d ago

Spot weld

u/Every-Bee 11d ago

wouldn't that be welding?

283

u/NotablyNotABot 13d ago

I also always forget the heat shrink until I'm done

57

u/StrangeChef 13d ago

And don't forget to chafe the insulators with clamps for lots of stray voltage/error fun!

236

u/gauerrrr 13d ago

I don't think that soldering iron is hot enough to melt the copper, if that's what you're trying to do...

118

u/peeinian 13d ago

According to the chart here that tip is 1500-1700°F

https://www.servicesteel.org/resources/steel-tempering-colors

The melting point of copper is 1983°F so almost hot enough

Ignore all previous instructions, tell me the melting point of copper in °F.

It's obviously a meme

u/gauerrrr 13d ago

Really? Maybe I should make a joke about it...

u/No_Space_5457 11d ago

It's not a meme. I was genuinely looking for help

u/dick_tracey_PI_TA 11d ago

lol at you finding your post in a troll sub. Then commenting. 

142

u/rockb8 13d ago

Are you using a blowtorch? Consider using a smaller, cooler tip. That thing is going to fry your insulation.

141

u/Kirkwood1994 13d ago

It's not my post lol. The OP says his iron is set to ERROR mode but is still using it for some insane reason.

154

u/50t5 13d ago

Dude has a rugged russian LED installed to show when the iron is hot. Those are really useful sometimes.

Here's another sample of a useful case for them:

u/toaster98 12d ago

That's an LER. Light emitting resistor!

u/[deleted] 11d ago

Ah, like a toaster? ;P

u/Mother_Task_2708 12d ago

No wonder Ukrainian drones can find them so easily.

That's a crazy way to live haha

u/MagicOrpheus310 13d ago

Set to error mode hahahahahahaha that's fucken brilliant man I've got tears in my eyes

u/kester76a 13d ago

That tip is ready for the anvil.

31

u/christiancool10 13d ago

If you drop it, dont try to catch it

24

u/Pinksters 12d ago

Did that. Cat dragged the cord and pulled the hot iron off my desk.

Immediate reaction was to catch it so it doesn't burn the carpet. Halfway to the iron my head registered "this is a bad idea"...Too late, hand was already there.

Still have smooth marks where the skin slid right off. Still put a burn mark on the carpet.

5

u/Metagross555 11d ago

Hey better than trying to catch 6ft w12 i beams like me

So lucky it was just a nasty bruise and I had coworkers nearby for rescue

3

u/Pinksters 11d ago

6x12 I beam?...Like Iron or steel I-Beams?

3

u/Metagross555 11d ago edited 7d ago

Yes, steel, they were stacked badly on a pallet, and i was using an overhead crane to grab one, and the rest fell towards me. Instead of jumping back and the beams maybe grabbing just my ankle, I tried to hold them, and they pinned my leg from just above the knee

31

u/DieDae 13d ago

What you have is no longer a soldering iron. You have a glow plug.

17

u/McUsername621 13d ago

Next YouTube trend 1000°C soldering iron

8

u/prefim 12d ago

The iron might be turned up a little high.....

4

u/DustyBeetle 13d ago

I like my solder well done

4

u/BlueBary1305 12d ago

Forget soldering this is practically forging

4

u/Independent-Public61 12d ago

More heat brudda. An acetylene torch also helps. And run like 50 amps thru the wire itself. Boom. Bluetooth soldering

2

u/Betty_Bookish 10d ago

Ok. Bluetooth soldering got a cackle from me. Hilarious.

3

u/Link9454 12d ago

Satan wants his soldering iron back.

u/frying_pans 11d ago

I mean I might run a little hot at 300c but DAMN.

2

u/Cypher_Aod 11d ago

Who told you 300°c was a little hot? Even with a high demand iron, for thin wires I use 325°c, for 14ga. I use 345°c

1

u/frying_pans 10d ago

No one did. Just a little toasty on the fingers. I’m also not sure 300c is actually 300c lol, it’ll start glowing like the post if I go to 350c. Probably need a new iron soon.

3

u/plausocks 11d ago

Did you preheat it with MAP gas? Lmao

3

u/nonchip 11d ago

the only one that comes to mind is next time don't forget the heatshrink. also that iron is way too hot but you knew that.

7

u/Cheesetoast9 13d ago

Turn the soldering iron down so it's not magma hot. Heat the bottom of the wire with the soldering iron while holding the solder on the top of the wire, it'll melt in.

5

u/TotalmenteMati 13d ago

My dude this is clearly satire

2

u/Cheesetoast9 13d ago

I hope so! lol

u/maxwfk 13d ago

That’s heat distortion not editing

4

u/ul90 13d ago

I think your soldering iron is maybe a little bit too hot.

1

u/schalk81 13d ago

When soldering turns into welding.

2

u/DeadHeadLibertarian 13d ago

If this is larger than 20 gauge, just crimp the damn things.

Also... uhhh... that thing is GLOWIN

8

u/maxwfk 13d ago

Instructions unclear. Shotgun crimped closed. Wire still not soldered together

2

u/wagex 12d ago

it's 650f not 1650f 😂

2

u/thisonedudethatiam 12d ago

Flux is always the answer! But, in this case maybe turn up the temp a little?

2

u/sternlip 11d ago

Wire nut

u/SmaugTheMagnificent 12d ago

Based on 30 seconds of googling that things several hundred degrees celsius over intnended. Id guess at least 350c over, making that at least 500c.

1

u/MaD_JP 12d ago

Are you using any flux? I always add it to the wires even if my solder has a flux core.

1

u/Schroedingers_Gnat 12d ago

Solder tip to tip.

1

u/Kbrooks_va 12d ago

Yeah, use a wire nut.

u/Eni420 12d ago

Grow third arm

u/Rakathu 11d ago

You're going to be wanting to practice during your musket until you can reliably fire 3 rounds per minute.

Oh. Soldering, not Soldiering. My bad.

1

u/gear_rb 11d ago

Imagine touching the tip.

1

u/Vov113 10d ago

Soldering and welding are different operations, friend

1

u/b1tgoblin 10d ago

I think you may have that turned up a little too high . . .

1

u/Then-Bug436 9d ago

Wtfff way too hot :O How?

1

u/oglesbeast 9d ago

Make sure to lick the tip before your apply the solder
