New here Looking for advice Clarke 130 E

[BishWeld]

Hi,
I have had this Clarke since new, feed always felt a bit stuttery.
Many years ago it stopped feeding, it requires a new transformer on the control board. (See pics)
I know this is mentioned a lot here, so does anyone know of a direct replacement, its 10 leg, but not all are used, as you can see.
And yes, I have tested it thoroughly, I'm just looking for a replacement transformer.
I know there is a couple of places in the UK that do board repairs, but I live in Spain now, the cost of shipping, return shipping and taxes would probably make it cheaper to buy a new unit!!!

Hello and welcome to the Forum !

The "SVTI" label on the small transformer represents the maker - Societa Veneta Transformatori Industriale. What's missing is the secondary output voltage and power rating. Fortunately this eBay ad shows it:

CLARKE MIG WELDER CONTROL PCB REPAIR SERVICE | eBay

This is a Repair Service! 12 Month Warranty!

www.ebay.co.uk

and it is 25 volts AC rated at 4 VA ( Watts ).
The small transformer only runs the relay on the board, so in fact a 1 VA or higher transformer would do the job.

[ I think that if you look at the relay you may find that it is labelled 12 volts, so at 25 volts the transformer output seems much too high. However, the rectifier is just one diode, so half-wave, and there is no smoothing capacitor. The DC value of 25v AC is 0.318 of the 35.35v peak, i.e. 11.24 volts.]

It will be difficult to source an exact physical match of a 10-pin 25v transformer. I think you will have to settle for 24 volts, and maybe drill new holes and add wire links from the PCB tracks to reach the pins. If you search on your local eBay for "PCB transformer 24v" and then post a link to the results, we can advise if suitable.

Eddie49 Thanks for the reply,
I just wondered if there was a direct replacement, rather than searching by pin out, dimensions, pitch etc, etc.
I'm sure there is one easily available, somewhere near what I want. Anyone know what the board repair companies use as a replacement?

Hi all,
I Looked up the Dongguan Yinli Electronics Co; YL-35-240080B. I found a conformity cert, but no actual link to the item.
Had a poke about on EBay and Amazon, I thought this looked helpful. Looks like it hits all the pin marks required, without extra drilling, its 3
vA, so near enough.
Depending on if it was the 2 or 4 out, it would just be knocking up a small link between pads.

EDIT: The same people also do a 12V one, maybe suitable for other welders.

That YHDC PE2820-1 does look like the correct pinout and would be easy to install - if you can find a supplier for the 24v version.

Hi Eddie, that is a 24V version. they also have 9 and 12V versions that maybe useful for other models.

That is a 24V version. I also just found this on Ali, appears to have the correct 24V 6 and 8 pinout for the board, a little more expensive but hardly crippling!
