  • 2001 Pipe pro 304 problems

    My machine has been acting up lately, while running it will go to high idle for no apparent reason, we will then shut it down and restart it and all is well for a couple days usually.
    I was out on a job yesterday and lost power to the grinder, so I checked connections and realized there was no AC power, I then checked my welding output and nothing there.
    This morning I checked it again with everything unplugged including the welding cables and still nothing, I forgot to mention that the LED display is also not registering.

    First place to look is your brushes. It's a great start since you have no display at all.

      I hope it is just the brushes, I'm not sure if this machine uses brushes because its a inverter and why would the motor go to high idle.

        Seriously? You own this machine and didn't know it has brushes?

          To Tell you the truth, no I diddnt know, I never gave it much thought since I have never had a problem.

          I know that my trail blazers do, Why would this be such a big deal, when I have electrical problems I take it to my repair guy and when they need welding done they call me.

            Well, PW, if you were as smart as 1997cst you'd have solved your problem already.

            So what kind of brushes are we talkin about? Toothbrushes, bore brushes, push brushes...

              TOOTH BRUSHES....

              Heck... I had no idea it had brushes either.... must have forgotten to drink a cold can of "Savant ICE Lager"...

              Looked it up though...See page # 58 of the manual (page 62 of the PDF)

              And I have absolutely no idea if they are related to your malady....

                Been my understanding a pipepro 304 is a genset with an xmt304 sealed up inside it. Regardless of make up the electricity to run any welder comes from the genset. So its going to have brushes.

                  Not Always the Case... There are "Brushless Alternators"


                  Brushless alternators

                  A brushless alternator is composed of two alternators built end-to-end on one shaft. Smaller brushless alternators may look like one unit but the two parts are readily identifiable on the large versions. The larger of the two sections is the main alternator and the smaller one is the exciter. The exciter has stationary field coils and a rotating armature (power coils). The main alternator uses the opposite configuration with a rotating field and stationary armature. A bridge rectifier, called the rotating rectifier assembly, is mounted on the rotor. Neither brushes nor slip rings are used, which reduces the number of wearing parts. The main alternator has a rotating field as described above and a stationary armature (power generation windings).
                  Varying the amount of current through the stationary exciter field coils varies the 3-phase output from the exciter. This output is rectified by a rotating rectifier assembly, mounted on the rotor, and the resultant DC supplies the rotating field of the main alternator and hence alternator output. The result of all this is that a small DC exciter current indirectly controls the output of the main alternator.

                    Yes thoose exist, but to size one to run a welder would cost about 50k and people would likely not buy a 70k machine. Every genset i work on has some sort of brushes. Dont think you will find an engine drive welder without rotor/brush design.

                      Don't know where you grabbed that $50K price but I am finding 20KW head units in the $600 on up range...

                        So show me a welder with this design. You wont find one. Also every industrial genset i have worked on is brush/slip/rotor. Pure wave dc comes this way.

                          Also as for my number justt referencing info from my genset/cummins classes. Ie onan/kohler gensets. Same question asked why a rotor..other ways had huge cost and limited applications vis load...etc

                              There are plenty of brushless gensets that could power an XMT304.... so why give "Portable Welder" a hard time for not being sure if it had brushes or not....????

                              Not ruling out a brush problem... since it has them...
