Miller Heavy Duty Foot Switch Wiring for Dynasty 200DX TIG

I just purchased a used Miller heavy duty foot switch. I can't find
any model numbers on the outside of it, only the Miller Logo. It has a
20' cable with a 14 pin cannon plug (M85049/41-12A)on the end. Only 5
pins are installed in the cannon plug (A,B,C,D, and E)the other 9 pin
outs are vacant. I think this foot switch was connected to a miller
300SS/with tig rig 300ss plus hi-freq. I would like to connect this
foot switch to a Miller Dynasty 200DX (but I sure DON'T want to risk
damaging it). I haven't taken delivery of the Dynasty 200DX yet so I
don't know what size connector it requires. Anyone know if this will
plug in without damaging, or will I need a different cannon plug? If I
need a different plug any information on wiring would be greatly
appreciated.
Thanks in advance,
Dudley

If it is a 14-pin conector then you can plug it right into your Dynasty.
Miller has used the same 1Kohm resistance potentiometers in their foot pedals for a long time.
You can even use brand new Miller foot pedals on 20 year old Syncrowave 300's, if you change the plug or the connector.
Syncrowave 300s have the older 5 pin connector.
The only 5 pins ever used for foot pedals are A, B, C, D, and E. A and B are the contactor control. C, D, and E are the Potentiometer contacts with C the high side, D as the common, and E the low side.
I like using the old Hobart cast aluminum foot pedals for our Millers. All you have to do is swap out the potentiometer and the cord connector.

Thanks Ernie for the information. When the 200DX arrives I should be ready to tig some material. Dudley

The only Miller foot pedals I have found that cannot be used with modern machines are the really old ones with 2 cables, both with twist-locks. These are designed to work with older dialarcs, goldstars and 330AB/P's.
You couls retrofit the foot pedal box, but it would be more work.
