Cordless Soldering Iron - recommendations?

Re: Cordless Soldering Iron - recommendations?

Hakko FX-901 is one option which is also easy-to-carry battery-powered soldering iron and cordless design that makes this iron very handy to use virtually anywhere. I recommended this for hobby handicrafts such as stationary models and radio-controlled models.

Re: Cordless Soldering Iron - recommendations?

Here is a photo of the other version of this soldering iron controller

This works a little bit different I have figured out how to go into the menu and set the sleep and shut down timers for how I want it to work on battery power

Quicko T12-942

I just love this version of this this soldering iron controller

I just have one complaint about it and that is that does not have the feature that when you turn the encoder switch to the left it put it into the sleep mode or the power down mode but I can live with it

That the Ksger model does have this feature but it is a pain to set the temperature you frist have to push the temperature encoder switch then you can change the temperature

But like said earlier I like and dislike some features on each one

But what I do like about both of them are the tips are that they are very easy to use and heat very well

Re: Cordless Soldering Iron - recommendations?

I tried the Ksger soldering iron controller on that Medical Grade Switching Power Supply
for some time and seems to not have any problems powering it and it works very well on battery power as well I have two different versions of this soldering controllers there are different things about each one that I like and some things I do like about them

Re: Cordless Soldering Iron - recommendations?

One final note I also ordered a 20 piece set of soldering iron tips for this soldering controller from AliExpress for $38.00

One final note on the power down mode the display still stays ON and as soon as you move it powers back ON and back to the set point

Re: Cordless Soldering Iron - recommendations?

Here is a picture of the setup that I come up with

All battery parts were bought at Lowe’s Store *

The USB charger converter $20.00 *
The battery 4amph $50.00 *
The battery charger $25.00 *
The soldering controller $13.00 * AliExpress

So for $103.00 I have a very good setup

I used a 5 amp re-set-able fuse going to the power cord

I still going to convert a ZD-915 soldering station and use the same USB converter housing to power this unit as well now that I found a 24 volt battery pack for fairly good price

One note I have seen a tear down ( on You Tube ) of this battery pack and they do use very good quality batteries in there battery pack

One other note what I like about this soldering controller is that when you do not touch the iron for a little while it goes into the sleep mode and if you still do not touch it goes into power down mode very important feature for it being used on battery power ( and very inconvenient if being you are powering it on a home outlet the power down mode)

Re: Cordless Soldering Iron - recommendations?

Here is the battery pack for a battery operated soldering iron

This unit cost $20.00 and very is hack and easy convert to power this soldering iron

Re: Cordless Soldering Iron - recommendations?

nice idea,
but it looks like they are still trying to offload all the old 900 series handles.
those are terrible - if the tip was any further from the handle you would need a picany rail to mount a scope!!

Re: Cordless Soldering Iron - recommendations?

I noticed some cordless T12 stations that use a power tool (slider) battery. $60 USD. Search for "T12 Slider Battery" on fleabay.
Versions available are Dewalt, Mikita, Milwaukee M18, Bosch 18V.
It's another way to go.

Re: Cordless Soldering Iron - recommendations?

and have about 500 medical packs waiting to be stripped.
i love these.
they are max 2 years old and few if any cycles.

Where are you getting them from

Re: Cordless Soldering Iron - recommendations?

just as well, with the cost of the cartridges!!

Re: Cordless Soldering Iron - recommendations?

It's all about how the heat is conducted to the tip, see eg EEVblog #1064
I would not say it's as good but in a comparison to my 80w Weller WSP80 soldering station the TS80 does not loose by much.
Put another way desoldering large caps on multilayer PCB's is not super easy with either of them.
However paired with my powerbank it sure beats it in portability: I use if for example on machines with soldered batteries:
Huge advantages in battery operation both in convenience but also in no risk shorting out a battery with a grounded iron...

Re: Cordless Soldering Iron - recommendations?

TS80 USB-C QC3.0 charge is apparently 9V 3A for 18W. You need a Quickcharge powerbank for that.
TS80 "Power Input: 3.6V-6.5V/3A, or 6.5V-9V/2A, or 9V-12V/1.5A ~ (QC 3.0)"

No boost-converter in TS80 teardown, the P-fet goes from +in to the tip and there is a step-down converter.

https://www.eevblog.com/2018/08/11/e...ng-iron-review around 16:45 the pcb is open.

Re: Cordless Soldering Iron - recommendations?

ts80 is about 20-30w i think - it has an internal boost convertor so i dont know the supply limits.

Re: Cordless Soldering Iron - recommendations?

Cordless soldering is mainly about the available power source. How many watts do you have?

Hakko FX-901, four AA alkaline batteries 6W (NiMh 5W).
TS80 USB-C for 5V at 3A, it's a 15W iron.

For the T12 (8ohm) heaters on TS100 and 951 clone stations:
12V power, 20W.
19V power, 45W.
24V power, 72W.

This all assumes the iron is well designed and does not have crappy heat transfer from heater to tip.

Re: Cordless Soldering Iron - recommendations?

TS80 is low powered shit though - no grunt behind it.
Jilien Ilet did a side-by-side with a TS100 on utube.

Re: Cordless Soldering Iron - recommendations?

Missed this thread, you can't beat the TS80 for portability:
Uses USB-C Qualcomm quickcharge and usually you would have a charger for your phone or even better powerbank with you...
I have one in my laptop bag: beats carrying around a large Weller station for simple jobs...

Re: Cordless Soldering Iron - recommendations?

I bought two Ksger batteries protection for this soldering iron I want try them out and see how well they work

Battery-powered T12 Soldering Station Dedicated 6-series Lithium Battery 24v25.2v Balanced Protection Board

Re: Cordless Soldering Iron - recommendations?

I like the Iso-Tip for field work but I wish they made a cap to cover it. Emailed Iso-Tip again about that. Butane irons have a cover/cap. Iso-Tip 7700 around $62 USD plus li-ion, looks elegant.

I see a KSGER T12 battery-powered station uses six 18650 2,500mAh batteries 6S1P with BMS. Brick is 25.2V 2A.
The BMS board alone is around $15 USD, and the batteries are heavy. It's alot of battery power.
https://www.youtube.com/watch?v=rKljvo9g0YE

A 12V->24VDC boost-converter would make 24V 3A from 12V 7.5A (80% efficiency), or 19V 4.7A 56W if using fewer batteries:
6S 22.2V 2.8A direct drive 61W
5S 18.5V 2.3A direct drive 43W
4S 14.8V 1.9A direct drive 27W
4S 14.8V 3.8A with 19V boost 56W
3S 11.1V 5.1A with 19V boost 56W
2S 7.4V 7.6A with 19V boost 56W

It's only full power for 10 seconds on warm up or soldering big joints.

A mini T12 soldering station, 907 handle, LED controller is around $25 plus battery pack and boost-converter. RC hobbyists are adding an XT60 input connector. I still haven't decided anything.

Re: Cordless Soldering Iron - recommendations?

btw a iso-tip with a high drain 21700 li-ion and a tp4056 board works great.
i also replace bulb with a white led and resistor in the bulb base.
the yellow package high efficiency tips work best.
the standard tips overheat and glow if you hold it down.
so you cycle it.
18650,20700,ect work too. but must be at least 15a rated.
tesla model 3 cells do ok in the one i did recently.
they can be a trick to connect to the recessed aluminum + contact but the right flux and a good iron will allow you to solder quickly enough to avoid damage.

Re: Cordless Soldering Iron - recommendations?

you are wasting your time with cells at 0 v.
anything much below 2v are usually not much good.
0v cells also carry a risk of dendrite shorts.
but the good news is that these cells are usually in such poor condition that even if they are directly shorted they dont have the energy to hit thermal runaway.
i have stripped hundreds of laptop and medical packs for cells to build solar banks with.
and have about 500 medical packs waiting to be stripped.
i love these.
they are max 2 years old and few if any cycles.

yes, but it gets better,
the bad "pair" once seperated you can sometimes recover one by VERY slowly charging it at about 20-50ma.
think of it like re-forming a cap.
i use a 5v supply and a 75ohm resistor.
the current is too low to generate any heat, so explosion risk is zero - either it charges and holds at 3.7v or it doesnt.

also, some packs are all-good.
just some cells are out of balance by maybe .5v so the internal board shuts the pack down.
once you strip it they are all good.
