    Sorry for no updates, we have been working long hrs on a UPS job, I got a quote of $ 1,734.00 to fix the welder, they said the Rotor is open and the brushes need to be replaced, not sure if this is a good or bad price, but its junk if I dont fix it so its getting fixed.

    Its been a good machine.

    Thank goodness for having a back up Trailblazer.

    To bad they quit making them 3 years ago, and doubt your going to see a pipeliner roll up with a scout bolted to their rig. So...show me a 200-400 amp pipeline rig that is brushless...goodluck.

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

    SIMPLEY...That Not All Gensets Have Brushes.... ...
    Where did i give him a hard time? Must have missed that. Again just pointing out how the machine works. However back to my point...tell me an engine drive which does not use a rotor/slip ring/brush. They dont exist, why......maybe someone will chim in. However i would bet....cost, design, and space are the reasons.

    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

    They're not rare ... exotic or expensive these days...

    For what it's worth... brushless designs are quite common in the Engine Driven AUX power industry worldwide....
    thruout the range.. 1KW - 900KW+........
    including brands like Generac & Kohler

    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.

    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 https://en.wikipedia.org/wiki/Bridge_rectifier"]bridge rectifier[/URL], 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.

    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....

    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.
