You can find and contact them on Alibaba.com. The person i spoke to was Mr king Liu.

The control and mosfet boards can be purchased without the ver 2.1 processor and then purchase the ver 2.5 processor separately.<br />No, the boards are not populated. The plans has a Bill of Materials and links to purchase the components. <br />No, the plans are not included. The welder will cost about $450 to $500 including the boards, processor and plans. It depends on the type of capacitors, case etc though.

After everything is said & done, whats the approximate cost here?<br /><br />Thanks,<br />DBiGG_Dnoreply@blogger.comtag:blogger.com,1999:blog-762737823950168623.post-12437708424500169362016-02-06T11:36:29.213-08:002016-02-06T11:36:29.213-08:00Jeff, That's a good price, never bought from t...Jeff, That's a good price, never bought from them before but you will probably pay shipping and tax on it. I just placed an order from China for $2.50 each. With shipping, 20 will cost you about $2.90 each. You can get a better price if you ask them for discount and you are protected by ebay. http://www.ebay.com/itm/1pcs-IR-IRFP2907-75V-N-Channel-MOSFET-Transistor-International-Rectifier-/161393641309?hash=item2593cf875d:g:mNoAAOSwEK9T60DT#shpCntIdFritzhttps://www.blogger.com/profile/01082504234684948258noreply@blogger.comtag:blogger.com,1999:blog-762737823950168623.post-69310894505988114152016-02-06T09:41:54.274-08:002016-02-06T09:41:54.274-08:00I'm currently in the process of building this ...I'm currently in the process of building this welder and plan on using 11 capacitors in parallel to equal the 3 farad. I've acquired various size 25v computer grade capacitors off ebay. Not from the seller that the link in the BOM Fritz has in the control pcb manual folder but from other sellers. <br /><br />Also, I have found the MOSFET IRFP2907PBF for $2.69 each from AVNET. Is AVNET a reliable source for parts? Has anyone ordered from them before?<br /><br />JeffJeffWPhttps://www.blogger.com/profile/02164448199603330468noreply@blogger.comtag:blogger.com,1999:blog-762737823950168623.post-38781748393785299132015-11-23T15:16:24.820-08:002015-11-23T15:16:24.820-08:00Hi Fritz, I purchased your boards and chip quite a...Hi Fritz, I purchased your boards and chip quite a while ago and due to infirmity have only just got around to looking at building this beast.
