Oh i see the hole now. I have better light. Yes, you probably had a failure. Lee is sleeping now. Will wake Up in 4 hours or so.

The fet error message means:
Underpowered battery(is It full?)
Failure
Reload your lipo and check carefully the machine. Look for burnt traces. If the machine does not resume work mail lee. He Will tell you what to do.

http://i63.tinypic.com/2l88as9.jpg I did the test outdoors under the Sun so the settings can’t be seen easily. I started from 4ms X2 Up to 9ms I think 4-5 ms X2 is enough. Beyond 7ms is too deep with my setup. Notice that nickel on nickel might need higher flux. If you weld on the same spot that yo...

4s on nickel 0.2

Just tested 4s on 0.2 nickel. It's more difficult than 3s but perfectly doable. I recommend 3s for nickel, if you only have 4s adjust it slowly and you will make it (depending on your setup)

I LOVE this thread. Amazing job.

"graphene" has indeed been abused lately. Many products put that Word in their products even if they don't have It at all. I think this is genuine graphene this time. MIT has a well deserved reputation and there's no need to sell smoke. Those golf balls.... I have my doubts. Maybe they add nanotubes...

It seems MIT has done It. Right now it is a slow and delicate proccess but possible anyway. Focused on extreme efficient filters atm. Video of the machine included. http://news.mit.edu/2018/manufacturing-graphene-rolls-ultrathin-membranes-0418#news-video-block Nanotubes of graphene are possible time...

Yes graphene has been reported to work fine. I use nanotech, they are flawless. The burst is the key. High burst and at least 4000 mah work fine as long as It is not overrated. Graphene and nanotech have around 130C burstX4 ah= 520 amps pulses(in theory) the machine is rated for 880 amps. For good w...

Cool. You are taking off. Have a nice flight.

Joku that lipo has a decent continuous C rate yet a tiny burst. The burst is the only thing that matters.
We need Big amps for thick strips.

What lipo are you using?

hey spongeworthy .Mail Lee and explain to him your problem.

The latest model is more resilient to 4s but i suspect (not confirmed by the creator) that it requires a better 3s lipo to provide fine results on thick/wide tabs. I always used a top quality lipo (the one spinningmagnets pointed) and i have the V1 so i can't confirm it. Latest users reported low pe...

Yes wire thickness matters a lot. It is a shame lipos are so C overrated. A Good lipo is a good investment.

Part of the power will be lost on heat and transport. Nevertheless you need 5 hours and you are going to make 8 hours (rated) packs at only 2 amps. You should be ok with that. I recommend you test on a cutter blade first. So you know how efficient your setup is in order to make perfect welds. Usuall...

Yes lipos work like that but they are often overrated. If those values are real it could work. It is normal if the points stick after welding. Make sure they are perfectly clean. Rub them gently on sand paper every now and then and use the right time flux. They should not stick so often once you hav...

10c? I don't think so. Too low. 0.2 requires big amps.

Yes, no need to parallel them. With Those lipos you will not have low performance problems.

Nice. If you put them in parallel remember not to use wired adaptors.
Use one of these

Yes. The korean post office is very efficient. Buy a good lipo. I recommend you hk nanotech or graphene.
Aim for 5000 mah and 40c +

Sure.

Nice choice. Everybody says mica's book is very good. This is also the right forum. The sphere rocks da house.

I watched your video. Your pen seems to have the points a little too separated.Try to get them any closer with some pliers. Are they clean? i rub them with sandpaper often. It improves the welds. The rest of the setup seems perfectly fine. You need to make more than just one weld to make they firm n...
