Snap on Promig 150 Duo

[Appyasme1]

I am after a rectifier for the Snap on Promig 150 Duo, any ideas where I can go for one, and I have a feeling that this machine could be a Cebora?

Weldfast are the 'new' Cebora people as I just found out, or Wilkinson Star may still do parts apparently.

Google image results yielded "made in Italy" on this one, so Cebora is likely.

Does it have to be oem fitment? If not, much cheaper to get a higher rated import rec off ebay

It would be better with the oem fitment.

Yes it does.

Need a manual for it?

If you could please

Here's one - for the Cebora version.

There's a possibility I may be able to procure a schematic for the pcb, but that's only a 'possibility' and will take a week or so if it's possible at all...

Don't worry about the drawing, the info you have sent is brilliant.Thanks.

No probs, give me a shout if you need any more

I thought about replacing the Diodes.I could re-build the rectifier with different Diodes.I have been in chat with RS they coud not help.If I could find out the values of the said Diode,T9441-1,I could breath new life into this machine.Any help would be appriciated

Sorry for the spelling.

Mailed Wilkinson today.They have not been back to me.I am sure they will.If they don`t I wll give their rep,Gerry Sone some stick

I'd imagine those are the same diodes used in everyone's generic low-mid range rectifier pack - press in ones, half +ve stud and half -ve.

Usually about 35A (sometimes 50A) low speed rectifier diodes.

In most applications they are actually underspecced for the load and are a major part of the duty cycle considerations.

If the rec in mine failed I wouldn't hesitate to swap out to a different design altogether - like one of the 250+A monolithic rectifier units.

Even the stud mount (threaded with a nut instead of press in) diodes with a braided flylead would be an upgrade over oem and definitely cheaper than buying a full rectifier.

Thanks for the good info.With out your help I would be stumped
