Unitek welders for sale

Post by ZAXBÎX » Sep 24 2020 5:18pm

A couple of industrial capacitive discharge welders I acquired a couple years ago. A unitek 1-132-02, 250ws; & another unitek 1-065-02, 100ws. Have two heads & a foot controller. Neither head is a parrell gap, I used a DIY handheld for a few packs. Besides the fact that they are industrial/commercial welders; the real caveat is the manuals & consumables to go with them. Units came from Hewlett-Packard; including their own setup procedures in the binder, with pictures; has resistance welding procedures for about everything, including copper @ varying thicknesses to other substrates.
I had visions of grandeur about building batteries & E-bikes for a living. A couple of years later; only a few bikes & a few batteries, it's time to move on. These machines routinely sell for over a grand a piece, not including all the goodies. I would like very much for another forum user to put them to use! (As I've learned so much here) Hoping to find this gear a good home in a sustainable industry & willing to take a financial hit doing so: that being said I won't give it all away, I have to recuperate some of what I have invested; arrangements, negotiations & contingencies are up for welcoming offers.
I'm located in northern Colorado, 🇺🇸. I'm willing & able to professionally crate the welders for shipping. My guess at shipping weight would be about 300#, as the 132 weights about 100# alone. My asking price is $1500 for everything Unitek related.
I also have hundreds of salvaged 18650 cells, a Thermo EC135-90 power supply, as well as a Hitachi V-1565 100MHz oscilloscope to part with.

Thanks, Z

Re: Spot Welding Copper Strips to 18650 Battery Cells

Not to be a dîck, but...

I've ran .20mm copper into 18650 cells without much of a problem, issues did arrive over .125 pure. I may very well be at an advantage with the machines I have, not to mention the dummy proof set-up instructions & manuals. I've only built a few packs, so don't take me as a professional. I acquired a couple of industrial type capacitive discharge welders a couple/few years ago. The 3rd-5th welds I did with the big one were with copper. I think the caveat is not the 250ws welder, but the manuals to set it up. Trying to account for a home-made handheld set of probes took a lot of trial & error, wish I would of had factory ones that were speced. I've held this knowledge a little too close the last few years. I think the documentation I acquired from Hewlett-Packard & Unitek may very well be the holy grail, at least for these machines; probably the baseline for any CD welder to perform. I wish I had pictures of the one copper clad pack I did, looked wild. I'm over my visions of grandeur, of making batteries & E-bikes for a living: so I'm selling it all off. (Posted it the for sale section) If it doesn't sell from here in short order & I have to list it on eBay, unless potential buyer wants to keep it proprietary; I'll publish all of the material, along with my own findings that I have documented. (That is as soon as I put the smoke back in the computer)
I've followed this thread since it's beginning, last couple years with a shît eating grin on my face. I regret not sharing my findings when I did, as I've learned so much here. Just thought I could corner a market & my own greed takes hold.

Not to be a dîck but...

I good friend of mine once told me: everything you said before "but", doesn't mean shît. That always stuck with me & made me think about what I just said.

You should share the manuals or STFU.

Tough crowd.

I agree all knowledge "should" be shared, but that does not mean we should expect it as if a right, especially when there is a lot of time-consuming work involved.

Yes please, do your best to share scans of this info, would be very appreciated.

If not the "complete set", at least start with a set of dummy proof instructions relevant to this topic here.

Thanks in advance. . .
