My dad has purchased a used Miller Dynasty DX200 with the error HEL P-8 which he thinks may be SCR failure.
Does anyone here have any experience of these and the resulting code.
The manual fault code details are in the pic below.
Are you sure that's the right fault code?
Looks like there is an error in that manual,
All the other codes are numbered 1=1 etc,
That #6=8 might be a mistake?
What does #8 say?
Looking on the miller forum, this is common. Could be remote foot pedal issue, use of pure tungsten, balled tungsten or poor earth connection.
Think the fault code is a bit of a generic one.
My dad has had every board out of this one and changed so many bits but still not got to the bottom of it. I don’t hold out much hope but he’s very persistent!
Yeah, he bought another some time ago so I don’t even know why he’s bothering. I asked that if he fixes it will he sell it, he said no he’ll keep it! I don’t get it
