Connecting a HF251D-1 to a DX200 Dynasty

[jessey]

I just purchased a used HF251D-1 and wanted to verify that it actually works so I connected to our DX200 in ac stick mode and it doesn't work at all. Can the DX200 work with the HF251D-1? I won't be using the DX200 for a power supply but just wanted to see if it would work because it's the only ac welder we have in our shop at the present time. I'm hoping it shouldn't work which would mean our HF251D-1 might be OK...

Any input would be appreciated.
Thanks

My gut tells me to be VERY afraid for the Dynasty...

would be concerned that the HiFreq would backfeed into the Dynasty and release the magic smoke....

this is just my feeling... no evidence...

H80N, Exactly what I was thinking.

Well yes it's a little stupid to say the least, that said, II don't know which hf box you have as no one tends to supply a serial number. Sooooo connecting straight to the 14 pin on the dynasty there is no 24vac power. Connecting to a 115vac source, won't make the dynasty work either without something to turn the hf box on, to turn the dynasty on.

besides your playing with fire here.

If the hf box is a 115vac unit, merely plug it into a wall plug, jumper the torch trigger to see if it does work. Why in the world you came up with the idea of plugging it into your dyasty is beyond me.

What do you plan on actually connecting the HF box to when it comes time to weld???surely not the dynasty. Do you have an engine drive or something? If so why not test with that?

If you had HF start enabled on the Dynasty and triggered the contactor, you might have smoked the HF251.

I don't have the schematic in front of me, but I'd assume there is a choke to isolate the Dynasty's own high voltage RF output from the sensitive solid state power supply which might, and I stress MIGHT, provide some protection. But it's a gamble with little to gain and a lot to lose. You'd come out better selling me that Dynasty for five bills. I'll see if I can Y two of them together and get 400 amps. NOT!

Seriously, though, I could use a second one so I don't have to unhook my Coolmate to go places.

I too am at a loss as to why you would hook up a HF arc starter unit to a HF output capable power supply.
