    Thanks to everyone for their input. I Got everything set up this weekend and it works beautifully. Very nice step up. Now I need a project!

      They will come out of the wood work from people and places you didn't even know existed lol. Enjoy the new machine and have a blast.

        Cdaniel-

        I'm running #6 wire on a 50amp breaker to my new 210 too. Looks like great minds think alike!

        ;-)

          my turn

          Ok, first off - woohooo I just bought home a new member to the "Miller" family

          I wired my "shop" (ok it's my garage but we can dream) a long time back with a dedicated box that came off of a 60 amp breaker on my main. I "think" that used a 6 ga wire (it's been a while). I ran an outlet off of that box located in my garage with a 30 amp breaker which was going to be for my welder. I ended up getting a nice air compressor that uses that one.

          So, I need to run a new plug for the mm 210. It's going to be about a 1' run from the box to the outlet, but then I will also make a new plug for the welder (or maken an extension - not sure on that one).

          So..

          I was thinking 10/3 from the panel to the outlet, and a 10/3 extension cord with a 30 amp breaker - sound good?

            In my garage I have a 10/3 line going about 65 feet with a 30 amp breaker. Been fine for my MM210 and my IR 60 gallon compressor.

              Or you can put the same 30A plug on each and use the same receptacle, one machine at a time, if that's convenient for you.

                same for each or both are running off of the same 30 amp breaker??

                I allready have the one, and it fits both so I can swap em out but I figure I'll be using air tools and welding and I won't want to unplug and plug over and over..

                  I don't think it meets code, and one day you will strike an arc on tap 7 about the time the compressor cycles on. Not a good idea.

                    If you want to use the units to it maximum potential, I'd run it on a 40 amp circuit. I ran some amp draw tests in the past for a fellow board member before he decide to purchase a 210. ON tap #7 and with the unit outputting around 200 amps, my amp draw on the input side of the unit was 31 amps, and this is on a circuit that averages around a 240V.

                      I only use one or the other. The compressor is always shut off while I am welding, and the welder is always unplugged when not welding My compressor is hardwired to the thing, so I just flip its switch off.

                        Cliff, you're good.

                        Brandon, you're good.

                        Don't sweat the high end draw. You won't trip a 30A breaker at 31 amps, or 35 amps! You will not be running beads at that draw for long with the machine's duty cycle.

                        Weld on happily!

                          ok, still haven't bought my stuff but should I just buy this

                          https://secure.ramweldingsupply.com/...iew.mcic?s=233

                          or rewire my welder?

                          I dunno, I'm only going a foot from my service - no big deal to put the 8/3 and 40 amp instead of 10/3 and 30 amp. I'm probably going to go pick up the wiring goods today..

                            Seeing as how its a foot away it wont matter which you use, number 10 or 8, performance wont be affected. I would rather use the 8 if you are using cable as the wire is stranded ad I would rather have that heavier wire making the connections. It fits the recepts better.

                              I rewired my 210 and used qa 25' cord which had been my extension cord. I needed it 99% of the time anyway and got tired of connecting and disconnecting each use. Wish you were in Houston; I could give you a couple of feet of Romex.

                                Brandon,

                                30A is plenty! No need to go to 40 amps. 40 is a wierd size, anyway. It will be too light for your eventual stick macine. If I were going to bump it up, I'd go to 50A right off the bat.

                                If I remeber right, you're in Sacramento? If you want to play with a 3035, take aride up here some day.
