  • **Need some help** Spectrum 375 w/XT30C torch

    Hey guys,

    I was given a Spectrum 375 by a friend because he had another setup and this one needed a torch. Bought a new XT30C torch, installed only to get a flashing cup error when the trigger is pulled. Air flows, but no Arc. The wires for the 4 pin connector had to be moved around according to Miller tech. The orange wire had to be jumped to the empty pin below it. Same cup error. Still getting air. Pulled out the circuit board, cleaned everything up, very gently. Reinstalled, same issue. Tech says it may be the board itself. There are no burn marks, no ozone smell, etc. Can someone please point me in the right direction for trouble shooting. If in had the money to drop on a new board, I could just buy a new machine . Anything will help, thanks guys!!

    Check that the consumables are installed in the torch correctly.. if wrong you will get such an error...

    Also.. here is the link to the manuals... just plug in your Serial number for the correct version..

      Thanks for the quick reply. I double checked the consumables, they are in the correct order and are all brand new. The cup was not over tightened. DLed the manuals, it also says to just check the consumables. So very frustrating. I just want to cut steel lol. Air supply isnfine, running through a brand new filter. It is set on 110v through a 15 amp grounded outlet. Should I try a 230 setup? Would that make a difference? Hate to be a pain in the arse, but do appreciate help.

            Lol, well here is the number:LK260218PSoooo, board damage like "replace your board" or board damage like "replace relay RC1" or something. At this point I am ready to just drop 200 bux on cutting discs and call it a day. This is for pure hobby, not work. Thanks guys.

                    If you had bought the machine from a store then they would probably have no
                    problem with sending a field service person to help you out at no charge. You can
                    try calling a Miller dealer close to you and see if something can be worked out. Might
                    not cost anything, might take 5-10 minutes. No offence to your abilities.
                    These service guys drive all over the place trouble-shooting problems.
