It is an optical illusion due to focal length magic. This is a side view picture of it and for my needs (so far just power tools pack rebuilds) there is plenty of headroom. For making large packs, I am sure it can get in the way but I haven't had that come up yet. Replacing the pole with a...

It is very consistent. I once tested it with a scale under the electrodes and it was firing always within a kilo (or two at most). It is important to note that the smoothness of the two rods sliding up when you weld is critical for this accuracy. Before I installed the linear radial sliding...

I didn't bother to take pictures prior to assembling (I doubt anyone would want to put as many hours on this project as I did) but took some today to give you an idea. It is hard to get the idea by looking at the pictures once assembled because what I did was to connect the welder and kCap with...

Received my kSupply and kCap a few days ago and I am amazed how well they work: Super fast charging (using a power supply for a Dell server with very close specs to the HP HSTNS-PR01) and nearly silent. These are superb products :D Thank you, Frank! I do have a question regarding the voltage...

Yes, excellent suggestion that I will research and test. Only downside is, since cooper's resistance is so much lower, it is harder to weld and you would probably need more power to get it to work. We'll see. The thought of using copper (not sandwiched with nickel) occurred to me but I have read...

The fact is, kWeld can do the .2 pure nickel well, but ONLY with the supplied electrodes. My beef with the supplied electrodes is (as good as they weld just after they arrive or you re-dress the tip) lack of repeatability. For consistent results, electrode gap, pressure and tip shape/size must...

Sorry if there is info in the forum about this topic but I could not find it using the search tool! Is there a way to connect 2 kWelds together to be able to handle more current? I don't need to double what one welder can do but I certainly feel the need for mine to handle probably 20 or 30%...

The one issue to consider when trying to enlarge the holes to use the kWeld's supplied electrodes is that if installed in parallel, even if you get real close to each other, the tips would be too far for the positive side of 18650 batteries. Not to mention, the grater distance in the electrodes...

Searching a bit more I discovered the exact unit in the picture posted by flashtel: On eBay. https://www.ebay.com/itm/Integrated-Hand-held-Spot-Welding-Pen-Spot-Welder-Automatic-trigger-Home-Use-DIY/402009868337?hash=item5d99a7c831:m:mdHw1HlIH_Ejthcn_yxsq2g They even have 3 colors to choose...

I never thought they would include the trigger switch on the hand held device but I am glad to see they did. Turns out there are quite a lot to choose from if you search for "spot welding pen" on aliexpress.com. The one I will order tomorrow is this one...

Welcome to the Club, flashtel! I can only comment on the device shown in the picture because I have done my fair share of electrodes and holders. The device could have a great deal of value IF it had thicker cables to connect it to to the welder. The springs make it a great device because it...

I was afraid you would say that. But it was worth trying. Thanks for considering the idea! I have read the whole manual and if I use short wires (around 15cm) made of AWG #4, with the battery I just bought, my kWelds complain of overcurrent. If I use thinner wire (AWG #8), calibration completes...

Here is a crazy question for kWeld's creator, Mr. T. I recently bought a new AGM battery and both of my kWelds units complain of overcurrent when I try to calibrate them. If I swap the battery and electrode cables with thinner ones, I am able to successfully calibrate them but I know I am...

@tatus1969. Perfect. Thanks for info! This is a well documented thing and there is a paper (among several) from a Chinese searcher in a university I can't remember, detailing scientifically his findings. I will post a link to it soon. Traveling overseas now with only my phone and missing my...

Question for Kweld's designer: Do you have any plans for adding a function in a future release that would switch the polarity half way through the welding cycle? As I am sure you know, DC spot welders don't form a similar nugget under the anode and the cathode for reasons we do not need to get...
