I was disappointed after with difficulty I managed to download the file from the aforementioned link.
At that address is an archive named "invertec lincoln.zip".
The archive contains eight files.
There is no any file with any information relating to the device which is discussed here (Invertec V270-S)
Moreover, two of files have nothing to do with brand INVERTEC from Lincoln Electric.
I refer to files called "inverter 3200.jpg" and "inverter 4000.jpg", which are, in fact, TOP DC welding machines,
well known on this forum. (Not Invertec Lincoln).
The other six files refers to INVERTEC indeed, but treats inverters totally different from the one which is in question.
We speak of differences of principle.
Those six files are actually ... only 5, because two of them shows the same information,
which refers to the model Invertec V100-S, V130-S. (Operator's Manual INVERTEC V100-S & V130-S.
Two of the five files are operating manuals, which can be downloaded from the website lincolnelectric.com:
- Operator's Manual INVERTEC V100-S & V130-S
Document code: IM585
http://www.lincolnelectric.com/assets/s ... /im585.pdf- Operator's Manual INVERTEC V350-PRO
Document code: IM731-C
http://www.lincolnelectric.com/assets/s ... /im731.pdfStt.pdf file contains the service manual INVERTEC STT STT & II
Document code: SVM129-B
It can be downloaded from:
http://valvolodin.narod.ru/schems/Invertec_STT.pdfhttp://elektrotanya.com/lincoln_electri ... nload.htmlInvertec V275-S.doc file contains the presentation of
http://www.emil.matei.ro/invertec_v275.php,
converted into Microsoft Word format.
It should be mentioned that the old Invertec V275-S and respectively the new Invertec V270-S are totally different,
and especially devices belong to different generations.
Finally, the last file, v270s_code_52047_52048_52049.rar can be downloaded here:
topic1930-15.html (page 2).
This is actually the only file that relates to this topic, and represents only a block diagram, no other details.
I mentioned these details in order to help those who have failed to download the archive mentioned.
I tried to download from
http://f-bit.ru/765563 and we received the message "This file is malicious, and Chrome has blocked it."
PS
Even though I have not checked practically dare to say that all these technical details can be found in section
http://valvolodin.narod.ru/schems.htmlI want to thank very much our distinguished colleague, who made an effort to put at our disposal a lot of very valuable technical information.
In my opinion, this is a powerful source of information for those interested in the field of welding equipment.
And, of course, generally in the field of power electronics.
