Which type power cord plug does Miller use on their Multimatic 255 machine? Thank you.

Be use the machine is capable of single or 3 phase power, generally the plug is not included. You decide what power supply to wire for.

If you’re only running it on 240v I use Nema 6-50 plugs on my Millers.

Thank you for replying cj737.

To update this thread, I have found the correct cord adapter and I will post the link below.

The dryer 240V receptacle is a NEMA 10-30. The Miller machine plug is a NEMA 6-50.

I use a Nema 6-50. I have seen several different plugs used. I picked the 6-50 and use it on all my stuff. I use and adapter for the 20 amp 220 things.
