  • 3 to 4 prong

    I know this has been covered but id rather be safe than sorry. Il be running a mm200 off of a dryer plug, 4 prong with 2 straight side posts one l shaped and a circle, to the welder plug. Ive seen everything from having to spending 80 for the wire to taking a dryer plug cable and capping the neutral wire and hooking rest to a welder receptacle.. ive also considered changing the plug on my machine to a 4 prong. Which is better? Any advice? Also i know doing this isnt ideal but I live in a rental house and cant wire in a dedicated 220v 50a breaker

    Check the wire gauge running to that dryer plug. If it will support the amp load for your welder, go down to the big box store and but a couple of feet of SO cord, four prong plug to match the dryer receptacle and a receptacle to match your welder plug and wire up a pigtail converter. Fairly cheap conversion and you'll be able to leave both the welder and the dryer receptacle as is. If you need extra cord length to make the run to the welder, add that in.

      Dryer service is usually 30A, this is an old MM200? I am not sure it wont have trip problems on a 30. A range circuit will work.

              Glad to hear it. It's not pretty, but it will do a good job for you.

                I don't know about your area, but I was just at my Lowe's dropping my grandson off to sell popcorn for his Boy Scout troop, and saw that wire in stock.

                    Don't they deliver? The guys around here have routes that they service on a regular basis. I don't see them cause I'm way out in the sticks but if I need to change out tanks I call and the next time they are in the area they drop it off.
                    Good luck with the welder.

                    PS-Beware the transport regulations. Around they shippers won't let you load if it is not in compliance because they get fined too if you get caught. This may or may not apply where you are.
