Suitcase Feeder Set-up with XMT 304

admin

So I'm finally getting these two paired up and mig welded with them some today. My Thermal Dynamics Hefty suit case feeder and my Miller XMT.They worked really well together but I have a question....the feeder has a switch inside for CC or CV mode, I have the XMT on voltage sense. I thought the feeder should be on CV but it seems to weld better on CC mode.Which one is correct?ThanksLast edited by polarred21; 01-18-2014 at 09:10 PM.Reason: Changed welds better on CC mode
Reply:Switch on feeder should be set to CV. XMT set to VS ,it will automatically put out CV, positive cable to feeder unless you are using most types of innershield wire.Miller xmt304,  Miller S22 p12, Miier Maxstar SD, Miller 252 w 30A, Miller super32p12, Lincoln Ranger 9, Thermal Arc 181I with spoolgun, Hypertherm 10000 ,Smith torches.

Reply:As said, the best way to run this would be to have the XMT in VS mode so it's putting out CV and set the feeder to CV to match. I've run my VS feeder off an XMT both ways, with the XMT in stick mode and the feeder in CC mode just to test it, and with the XMT in VS mode and the feeder in CV. Wire runs much nicer in CV than in CC..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.

Reply:Is your feeder a voltage sensing feeder?If not, the XMT should be set to mig mode, not voltage sensing mode.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720
Reply:The Hefty is a VS type feeder as far as I know..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear. Actually, a government bureau is the nearest thing to eternal life we'll ever see on this earth! Ronald Reagan
Reply:Thanks for the advice. I now have it set-up with .035 ER70S6 with CO2. Here is the old thread on the feeder purchase and my dismay with the fluxcore that came with it:http://weldingweb.com/vbb/showthread.php...-TA-dirt-cheap
Reply:Y .ou will be more than satisfied with that setup once you get it dialed in . I have a few different suitcase feeders, 1 remote control and 3 voltage sense and I cant tell any difference in the way they function on my XMT . If you are dedicating the feeder to the XMT you might want to consider fastening the ground lead on your feeder to run with the welder ground to eliminate tangling of the extra wire.Miller xmt304,  Miller S22 p12, Miier Maxstar SD, Miller 252 w 30A, Miller super32p12, Lincoln Ranger 9, Thermal Arc 181I with spoolgun, Hypertherm 10000 ,Smith torches.

Reply:The VS mode on the XMT is just a mig mode but the welder output is turned on.Mig mode waits for signal from feeder to turn welder output on.Both modes put out the same type of CV output.Says VS to match up with a VS feeder.
Reply:Thanks for the feedback. I have welded up almost all of a 14 foot trailer frame with this set up and it has performed well. I attached the feeder VS wire to the ground clamp as suggested and helped out a lot. Still running the XMT on VS and the feeder CC. I have tried swapping back to CV mode several times now and it just won't run in this mode, output appears intermittent. But by design, isn't this the mode it is designed to run? It is welding really well in CC, I just want to understand this for my own knowledge.
