Is it possible to purchase a rebuilt Board or get someone to rebuild one?
Can't seem to be able to get wiring Diagram with Component ID's.
Any help on this?
Thanks

And you won't either considering that unit isn't made by Lincoln. did't notice the Made in Italty sticker?? There is nothing you can do to repair the board/s anyways. Don't even bother! All components are italian, some are oem#'d, and several are factory programable chips.

TS24106-40 INPUT BOARD $416.15 USD
S24106-41 CONTROL BOARD $426.57 USD
S24106-42 MAIN BOARD $1,315.60 USD
his is why I hesitate on Lincoln Products.
The Unit new doesn't cost this much and thats why I'mm looking for somebody that can repair a board, but I don't think you can get the parts list for the componets on the Board !
**** I could almost fly to Italy and back for less money

Yes, there are products in every brand that you have to be warry of, the Procut 25 first off had alot less warranty than the other products Lincoln actually manufactured. What is the problem, is it just not switching from 115 to 230? It usually locks itself in 230 if there is a switching problem.

I was able to get the complete Schemaic and parts list, now to find someone to read them and give estimate !

What are you looking to find out? What is wrong or what is the machine doing or not doing. I can read a schematic and tell you what is what.

I guess I should have said I'm interested in finding someone that can test the Componets and replace what is bad
I'm going to check around the Ivy Tech School for someone in advanced Electronics that would be able to trouble shoot the possible problems.
I can read the Schematic but unable to determine the various functions of the Electronics and values.
I thought someone might know a person that would be able to diagnose the
potential problem and repair same , and was checking the guys on the board.

Yes, and you will notice that most of the parts list is in Italian.
Alot of these parts are programable chips, how are you planning to go around that.
NOT WORTH FIXING AT ANY COST!!
These boards are mostly SMD's, surface mount devices. Takes a specialized shop to replace these. Going to cost you a whole lot of money and the charge is generally 50% that of a new board, even if it doesn't work.
We also repair boards, and I wound'nt even touch this one.
WHAT IS THE ORIGINAL PROBLEM??

um... would you happen to still have that schematic and parts list for
the Lincoln Pro Cut 25??

Flying to Italy is one thing. Carrying on an intellegent conversation with the locals (once you get there, is an entirely different matter).:eek:

I would give these guys a call. I have never used them but have heard a lot of good things about their work:

I like to keep it light. Part of my charm. Would you prefer me to be an oger?

Hi, so you see, you should have bought something made in China, at least when it goes wrong you can get more for it as scrap parts than bothering to repair it....LOL......you're probably being punished for buying foreign goods.

Pretty much...
You might have some success in asking a tech student to look at the unit -- however, it may take a long time for him to troubleshoot the unit, since he would not likely be experienced with welding equipment in general, to say nothing of this specific unit.
I'm an electrical engineer by training, and when someone hands me a faulty circuit and a schematic and I've never seen the device before, it can take quite a while to simply determine what the circuit is supposed to do when it works... let alone discover what went wrong. Sometimes, you get lucky and a component is visibly burned, exploded, etc... but sometimes you don't and you have to do more involved troubleshooting.
It's relatively unlikely that any of the custom-programmed ICs (chips) failed unless the unit was subjected to a lightning strike or other catastrophic event, but one thing to keep in mind is that components sometimes need to be replaced with identical ones for safety reasons (many times, close enough is OK, but sometimes there are critical parts). Will it be possible to determine the critical ones from the Italian documentation?
I hate to call it a lost cause, especially since I enjoy fixing "unrepairable" items for my own use... but when you have to pay someone for his time, it gets expensive fast. (My "friend" rate is $35/hour and my "general" rate depends on the type of work, but it would be substantially more).
yep you guys are probably correct on all counts; however, I see a lot
of opinions and not much else...
1. this unit is not mine. I told the owner to buy a new unit... nope don't
wanna do that... so...
2. I enjoy this type of work - learning as I progress.
3. I am doing this out of the kindness of my heart.
4. I have done repair work similar in nature to this for
about the last 25-30 years so I feel confident that I am
up to the task.
You are correct that it will take a while, (been at it for
about 2 months - mostly some time on weekends and spare
moments between workdays ) simply for the reason that
I have to reverse engineer the thing so that I can figure
out what the people whom designed it in the first place
were trying to accomplish. Once I get to that point
then I am capable of doing mock up test circuits to
validate the operation of the various circuit boards.
So it really would expedite things if I could get my
hands on the full schematic.... barring that I shall
proceed....
.... why do I have the feeling that jonesiera is
no longer posting ..... :(
com'on jonesiera where are you?

If you decide you need some assistance these guys might be able to work on it.

Well, I finished the single sheet schematic but I guess I wont be
uploading the 1.4Mb pdf schematic for your enjoyment because of
the miserly 100K:confused: forum file size limit :(
....oh well.

Some opinions are accurate. My electronics guy looked at onje and said,,, sheet.

Guess he didn't get it fixed, eh? :D

I bought a new unit. We think it is in the tip safety circuit and had a schematic at one time but my guy was gone and we needed to enlarge it to make it readable. I might fool with it again this winter and work our way around the problem. One of the reasons I had got that particular machine was it looked like it was off the shelf mechanical parts to some extent but the boards had logic on them anyway, this was when the inverter types were coming which had everyone scared anyway. So much for that philosophy.

My Bud is pretty good at this too, not a hobby type, one of the best hands on mechanics I have ever met in the sense he can usually put his finger on the problem. If it would have been something we could do it would have been done.

I am in Michigan also - please pm me.

.
I strongly recommend against bypassing or defeating the safety circuit, or any
other circuit for that matter.
It DOES work and is there for your protection as well as the units'. If the unit
wont work because of a "safety" fault chances are good that it does have bona-fide
fault which the safety circuit is picking up...it needs to be investigated and
corrected before the unit will perform.
ok... I found a site that has the capability to hold the
large file size of the schematic I generated.
If you are so inclined, proceed to:
http://welderzone.com
go to FORUMS/WELDING MACHINES/LINCOLN
and look for the thread "Pro Cut 25" ((shouldn't be too hard to find
only 4 threads there)) schem is attached to the second post....
regards.
Hi, I have posted the full version of the Lincoln Pro Cut 25
schematic at the Welderzone . com forums for you viewing pleasure.
If you would like to view it go to Welderzone . Forums . Welding Machines . Lincoln . Pro-Cut 25
:cool:
enjoy.
mk77
see the Pro Cut 25 thread under the lincoln forum at welder zone
for the single sheet diagram....
