Thanks for the information.Ihave contacted them and they have no idea what the problem is. They will have to contact the factory to see if they know which board caused the problem. I am on the east coast and shipping for a repair will not be good sense throwing good money after bad. I have asked for a schematic ,but from what I have heard that doesn't happen ,so I do not know if it will be fixed kinda sad only 4 years old very rarely hobby use,
Thanks Woody

I am still waiting to hear some information determining what has gone bad in my four year old weldall 256pi without any hope of help . this scenario is beginning to become more familiar with everything I have been able to read about these welders.not worth sending in for repairs,no schematics available ,model discontinued,and so on. Any Help out there?

I read the post and took his mention of an address for the schematics to be in reference to the tech@lwelds.com email address. In any case, I'll send Simon an email to see if he can help.

The digital display on those units may need to be recalibrated and you can do that on a pot.

Adjust HF points to .035" to see if plasma problem is improved and also try pressure at increments of 5psi from 40 to see if it helps provide a more stable arc.



Thanks for the email address for schematics. On the other suggestions, I have already adjusted the points, and the plasma problem is that it doesnt work, it was unstable last year, but this year it doesnt work at all.
