  1. Default 2013 powerPlasma 50 - Nothing over 20Amps?? Torch volts way low too suddenly.

    Hi all- For starters- This may not be a PP50 issue... It's all part of a CandCNC BladeRunner/Mach3 system.
    ISSUE: Suddenly- the cut quality went south... The Torch Volts- took a dive too. Nothing is as it was then cutting normally just a few weeks ago on last project.

    A) The CandCNC system has a Direct Current probe option which it has an internal test and calibration routine, which passed. So I 'think' it's not that part.

    B) talked to support to Mark tonight- Did not know that the unit starts in pilot-arc mode (20A) for a sec or two.. then Xfers into the current setting as set by the user. .. The Front Display only registers the user- setting. it does not offer any real-time display. (as was mentioned, but this 2013 unit does not).

    I replaced the Ground Clamp and new lead-in and bolt down. . Cleaned all contacts. Checked all wiring....

    C) I dialed the face from 50 to 19 (lowest settig) and no matter what, the current reads the same every time. Torch Volts set to 110V consistent for years is now in the 70's and 80's and seems to be up down to maintain .06 cut heights.. crazy fluctuations.... Sometimes it hit 107.. Torch sinkes and break away till it stops.

    So- I am thinking there is some 'Xfer' circuity that takes the unit from Pilot DC current mode (20amps), then switches into User Setting-based current .... Anyone have thoughts or opinion. recall - this is NOT a HF start. S45 Machine torche from Everlast. Trifimet unit.

    Looking for a DC amp meter I can use to verify the CandCNC DCP is working. My inline only goes to 10A. The Fluke 325 AC/DC A-clamp on to 400amps is $$$ 290. Ouch but boy do folks love it. reads down the 50ma... for those leakers. Hmmmm Xmas early???
