Still a great welder. Working fine both solder and welder and my one and only reliable device.
That's my experience so far.

Yes they are in stock. Lee always has some units ready to ship.Check the first post under "disclaimer". Instructions there.
There are other welders at the sale section if you wanna take a look.

this project is so amazing. You have done an impressive job.

Sorry. This board was sold many days ago. I forgot to update. I apologize.

Nice review mate. Thank you.

Yes. You can weld nickel for parallel and copper on It for series. That can be done.

No. Copper on copper makes poor welds.
Wide tabs is the way to go.

My source is good but they sell kilos.

The courtesy strips sent by lee are 0.1 plated. You will destroy them on 4s. Test them with very low settings. For any question about how to use the welder you can watch this video 75XBlGjcBVQ For 0.1 copper i use 7-8ms X2 at full battery, as soon as the voltage drops i rise one ms and make a few mo...

Welcome to the club. So you have gone straight for 4s... Go slowly. Some testing is recommended as 4s has different flux times.

I did a flat pack for electric skateboard. 10s3p samsung 30q waterproof 60amps shared port bms

[youtube][/youtube]I have for sale a very light skateboard. It's been used very few times, i have many other builds so i want to sell those i barely use. It has a very high performance battery welded with copper. Made with sony konion vtc6 6s2p and 60 amps bms. Fvt 120amps esc. Speed deck. Maytech v...

Aluminium is extremely difficult to solder.
Also is not magnetic.

I did a second part of the pen video. Now with interchangeable tips.

So what?

Sorry... No english. I guess they will make some as soon as they are done developing and start mass production.

There's very few information so far but the official news is that Chint (chinese energetic multinational) Has bought 25% of the c...

Copper needs 4s. 3s has no effect at all on It. I use Two 4s nanotech in parallel. The reason for wide strips is that copper on copper makes poor welds, also i like the wide tabs method, series and parallel at the same time,less work and much better conductivity and heat dissipation. Win win. Those ...

Nice video ty. Yes i think it could handle 0.12 because i did 0.2 after all but i do not recommend going beyond 0.1 This machine was not designed to weld copper but nickel. Pushing beyond the limits will kill the fets in no time. The Heat and difficulty at 0.1 is considerable. I didn't test It mysel...

I guess you didn't visit this thread for a long time. Yes i welded many copper batteries. That one is 0.1
I succeded welding 0.2 but it's too dangerous for both the machine and user.
0.1 is perfectly doable with the Boss welder.

I did a welding pen and i taped it. I hope it helps people to do their own welding pens.

Well after my failed experiment i did my copper battery as usual, this time i didn't tape it as it is prety similar to another build. Nothing new to explain so no point for a video.

Great! A build with video. I will add It at the builds post on the first page.

Well i have been sick and didn't talk about It anymore. The experiment failed. The nanolayer of carbon dissolved in the water so i don't know how long It would protect in real life conditions the tabs. It can be improved by applying more heat with the torch but since the tabs are so slim the metal w...
