A right size resistor to limit current?

Longer avg6 batteryleads and or smaller and worse connectors . Not recomended mut if you keep them under max allowed lenghts if will loose some current..

Edit: meant 8 or higher awg..

If we are talking about the same thing, mine are on the outside of the swingarm.090E0963-D550-4531-A432-F673AE91E394.jpeg I have thouse like that too. I understood that he was talking about the little plates that come with motor and not thouse frame/swingarm parts. My mistake. And yes you can insta...

Can anyone please explain how to properly install a 5KW QS (205) on an EEB frame? It comes with two bolts and a rectangular piece on each side of the axle, but with both the rectangular pieces and the freewheel, it won’t fit. I don’t have a disk on yet either, I’m going to go get one today. I can m...

Will someone please be kind and explain why something like kSupply exists? Why can't i just connect an appropriate/cheap power supply up to 8.1v to the kCap? However 2s 18650 wouldn't work->4.2x2=8.4v? Because cheap powersuplies dont have current limiting system and will destroy thenselves because ...

I've done it! I recently purchased a 3D printer and have designed a front fender mount for the Mudhugger front fender on the USD-8 fork. In my excitement to put it on and test fit it I didn't take any pictures of it fresh off the printer :P . Was using a fast print setting and a thicker layer heigh...

Would such a 12v battery be enough for spot welding with kweld or maltronics? https://www.biltema.se/en-se/car---mc/mc/mc-spare-parts/mc-batteries/mc-battery-smf-2000029838 It looks like very tiny cm battery so maybe it can weld very thin nickel but it will be very hard for the battery. It is also ...

Okay how should I say.. First there's a touch with some sparkles after that there's a good weld with nickel plate melting, but at the same time liquid is coming out. :? *edit* also twice a small flame came out. That looks bad. Under 20J there should not be any burning or discoloration with 0.15mm n...

Is that normal that the K-Weld can burn through the Battery that Electrolyte comes out? Probably Not. So has this happened to Someone else? New firmware versions have anti arc features that reduce the risk of puncture but it's powerful and capable device so with too much energy it melts through. Th...

Quick update I received my K-Weld after few welds liquid came out. First i thought this was Water from previous use but turned out it came from the "Lanzhd" Cell. I had the setting on 9.5 Joule automatic However i reduced up to 2.5 Joule and worked better. I measured the Cell voltage and still seem...

I do have a sample of some .15 nickel plated copper ....and it is available but not cheap. But useless to me unless I can get good welds with it ...which is why I asked. I tried some at 25j with the stock electrodes and the welds were not good. I will have to try a higher setting or different elect...

Ossivirt ...so 50j and you got good welds for .1MM nickle plated copper? With the regular electrodes? I now have some .15mm nickel plated copper so it sounds like I would have to even use a higher setting ..... I used just bare copper. I tried plating it also but did not receive any benefits for we...

how good are the welds compared to sunkko ? sorry for the dumb question.. but im tired of my sukko which delivers self releasing welds. :flame: :shock: :evil: so im thinking about a k-Weld. How to best describe the difference :roll: I did multiple welds to 0.15mm nickel with sunko and prayed afterw...

My mistake ....LOL ...I meant .15mm copper of course. So has anyone successfully welded .15mm copper with their Kweld? It should be possible. I have only 0.1 and 0.2mm. I made one battery with 0.1mm and it welds ok at 50j and my battery amps are 1500A. 0.2mm I have only tried for a few welds and I ...

I have front mudhugger under the mud. It is there just with epoxy and time will tell if it stays in place. What Mudhugger front fender do you have? The standard length one or the long one? It looks like you have the additional extender as well. I have the longer rear fender along with the fender ex...

I have front mudhugger under the mud. It is there just with epoxy and time will tell if it stays in place. Originaly I just put it on with hotglue but it flew out after first ride. It was horrible to glue there and try to get it straight and not to rub anywhere. Oh and it's nice when you are holding...

My biggest problem with welding copper with kweld is that it seems so hard to make good weld at negative end of the cell. Positive is easy and as strong as 0.1mm copper can be I think. Negative maybe needs some extra joules but I am little afraid of it because I already made one hole and smelled th...

My biggest problem with welding copper with kweld is that it seems so hard to make good weld at negative end of the cell. That seems to be related to the fact that kWeld uses DC current, although I have on my list to do further experiments to see if it isn't actually related only to arcing. I alrea...

Just as a note: The average Amperage/mm² = 4,459A/mm² pure nickel @ " optimal Temperature" [/b] 6,619A/mm² pure nickel @ " acceptable Temperature" [/b] 8,918/mm² pure nickel @ " poor/hot Temperature" [/b] How/where could I get a similar data (amps/mm2) for pure copper? Thanks I don't know how to ca...

ossivirt, did you use standard copper electrodes or other material?

Standard kweld electrodes.

Ps: I hope this is not too much off the topic. I have not seen much this kind of test numbers around this welder. I find this very valuable! I have some ideas: - can you try slitting the strips, because this will help current guidance - your razor blade is probably thicker than a battery can would ...

This is very usefull information. Where did you get nickel plated copper? And what are you using for power? I just got my copper from ebay and plated it myself. I have not really find any sellers online that sells plated copper :roll: https://www.instructables.com/id/High-Quality-and-safe-Nickel-Pl...

I tested some nickel plated copper with the kweld. Difference is not huge compared to bare copper but at 0.1mm I noticed that it made it just slightly stiffer when I ripped the strips off. Copper is so soft that when it stars to tear it just keeps going and my plating reduced this effect a little bi...
