Re: BOSS LEVEL CUSTOM SPOT WELDER

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...

Re: BOSS LEVEL CUSTOM SPOT WELDER

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.

Re: BOSS LEVEL CUSTOM SPOT WELDER

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...

Re: BOSS LEVEL CUSTOM SPOT WELDER

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

Re: BOSS LEVEL CUSTOM SPOT WELDER

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...

Re: BOSS LEVEL CUSTOM SPOT WELDER

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...

Re: BOSS LEVEL CUSTOM SPOT WELDER

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.

Re: BOSS LEVEL CUSTOM SPOT WELDER

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 +

Re: BOSS LEVEL CUSTOM SPOT WELDER

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...

Re: BOSS LEVEL CUSTOM SPOT WELDER

It is weird. 0.2 nickel is Nothing for this welder. Mine melts nickel above 10ms usually 7ms is enough. Can you post a pic of your setup? Can you try another lipo? Try to set the multistage multiplier X2 If you can weld 0.1 you can add more layers yet you must be able to weld 0.2 and beyond. Others ...

Re: BOSS LEVEL CUSTOM SPOT WELDER

If the price difference is not too big I'd go for the 60c
With 4000 mah you can probably make a 10s 6p with one charge. I don't pay attention to that and Refuel the lipos as many times as needed.

Re: BOSS LEVEL CUSTOM SPOT WELDER

They look perfect to me. Did you test those times? If they are good it is perfect. The cooling mod is recommended or a must depending on the behaviour of your machine, weather.... if you can't go any further than 50 welds you should do it. It is very easy and cheap to do. I never have to stop since ...

Re: BOSS LEVEL CUSTOM SPOT WELDER

I am more than glad you fixed it. It is true that lee used crappy b grade lipo but it is a hobbyking lipo anyway. Some people reported issues at other forums. Thin wires and wrong parallel connectors are to blame. I wanted to make a video about common issues but I am very busy lately. You are right,...
