  • Hobart R-400

    i bought this machine used (dont know much about welding (yet!!). it was set up for 460 3 phase, and worked nicely. i changed it to 230 and i cant get an arc. my power in the shop is only 211 on the meter, im wondering if that could be the problem? theres 3 switches on the front 1.power 2.remote/local 3.remote/local. The power light and the fan are both on.anyone any clue??

    Another bargain on an Industiral Machine...that just will not work on residential electrical service...check with your local electric utility to see what it will cost to upgrade your service...if they will.

        He is serious and right on. Hence likely the low price for the machine? They are not designed for home use.

            In all fairness, he didn't ever SAY he was trying to run it on single phase, just that he changed it to 230. There is such a thing as 230V 3-phase. Although I have to admit, it certainly sounds that way. Oldjunk, you need to provide a little more info.

                Yes at 210 volts input you should get something at output. Do you have the owners manuel describing the voltage change over? If this is the machine I am thinking of there are 6 1 amp fuses located on the left side of the heat sink. Check them. The switches on front should be on local. If that fails the control board could be bad or the connections to the board might be corroded or loose.

                  Are you SUPPOSED to have 240V or 208V on your 3-phase? Both are VERY common, but are not designed to be interchangeable.

                    Hi. I got a similar problem, but need to convert from 220V to 440V (3 phases) but don´t have the wiring diagram. Could you send a copy electronically or an explanation for the voltage change. Thanks a lot.

                      Did you look inside the cover of the machine?? Almost always, these things will have a diagram pasted somewhere.

                        dear welder friends

                        Sorry, but there is no wiring circuit drawing inside the cover or anywhere else inside or outside the cabin. Unfortunatelly the operation manual was lost by the previous owner. The only information is about a litle box inside the cabin where one can change the jumpers in order to change the operating voltage.

                          Voltage change acomplished

                          Dear friends, a friend of mine did set the machine from 220V to 440V. Of course he is an specialist in the area. Thanks to all for the atention.
