    I got back from lunch yesterday and the shop girl approaches me and says I'm to come inside with her.
    Something about needing to check some fuses.


    So I go strolling inside the shop and find out the plasma table isnt firing an arc.

    I asked some questions and ended up drawing a blank.

    Cybermation .... anybody ever trouble shoot a plasma system?

    It does everything save for creating the arc.


    didn't even have a contact number for the factory, at the time I was scratching my knogin.



    any advice would result in suds being sent your way, if the info results in an action move for Monday.


    cant beat that with a stick of sil-fos dipped in roof patch ... now can ya?

    I've never had the opportunity to play with one of these machines so I know near zero about them. I asked Mr Google:

    http://www.hypertherm.com/technology/long_life.htm

    This appears to be a good summary of the inner workings of a typical plasma cutting system. It's where I would start from.

    Have you checked the tip and electrode?

    They get worn and cause problems.
    Get back to work.

    R-12...

    The person to contact for cybermation Is Pete at the lockformer company in Chicago...I will have to look up his number, but first lets do a few things, they may seem rather foolish for me to suggest this but...


    First and foremost of course is the Ground, The table must have a good ground and the power supply should be grounded to the same lug as the table

    Cybermation is the table that lockformer built during the 80's and I have never heard anyone say anything good about the cybermation set up.,

    ok once we have a good ground established, it's time to take the torch apart
    The top of the torch and the bottom are threaded together, so seperate them .
    inside the torch there is a gaget with two tubes on it that form a Y....one of those tubes delivers the air supply and the other connection is from the power supply

    that assembly gets removed from the bottom of the torch , and that piece is a very common piece for the operator to break , causing a short in the torch and no plasma spark

    Ok try that and if that doesnt work we can go on from there

    1 more point!
    the machine that we used was a three phase machine, however it was connected single phased( using only two of the three hot wires

    ok , Pete at lockformer ( 800 441-2840 ext 3220 )

    pete has assisted with the computer end of the vulcan system
    electricial questions etc. He will do all he can to help

    wait untill you hear his response when you tell him what you are working on

    BTW the piece I described inside the torch needs to be insulated from the air tube with a piece of shrink tubing and the whole assembly insulated from the body of the torch

    I hope this helped

    Instead of working on something you know nothing about (DIY), why not call a technician qualified and certified in working on this equipment?

    Because there are none left for this POS... Just ask Pete at Lockformer... he's the only one.

    Thank you. This is exactly what I came here seeking.

    I like it when someone who knows about something is willing to pass it along, freely, to someone they respect.

    I believe you know I would take this only as far as I felt comfortable going ... and stop there. At my own discretion.

    I have only known two industrial mechanics, personally, in my entire lifetime.
    Maybe more ... but few and far between, to say the least.

    Finding someone to work on this system is outside what I do, regularly.
    I tried, Friday. No luck.

    So I came here and found just what the doctor ordered.


    Thanks.

    Troy, I dont know what you feel about the trade, but I believe that a seasoned HVAC/R mechanic is at THE Pinacle of industry! Any Industry!!!

    Right up there with bio-med techs and industrial mechanics.

    Only dif being ... we get paid less ... in some instances and receive a lot less respect.
    Pity.


    With all that we do in our day to day affairs ... we are qualified to know when to proceed with a repair and when to stop and ask for assistance.

    If anyone thinks less of our trade skills and people ... that's their problem.




    as far as why I would want to explore a plasma table to repair it ...
    1) it is down. My new employer wants it up. It takes five men to do what that machine does with one person running it.

    2) my employer asked me to check it out. And so ... at the advice of DiceMan and others here. .. (many others in fact), I simply keep my big mouth shut and do what I am told

    3) I am curious.

    4) I was being paid to troubleshoot an electro-mechanical system. Didn't seem to me like rocket science or nuthin'....

    if nobody else at the shop comes up with a solution and I carry Pete's number in on Monday ... won't that look like I did something with my brain ...?

    I've worked on my own portable plasma cutter. Not much to it, really, air and electric.

    Like has been mentioned, the torch tip is a consumable...

    You have no arc. Does the Xformer receive primary voltage?

    Is your ground cable connection good on both ends?

    Have you called a pro?

    Troy:

    as the hvac_czar has stated and I will confirm

    There is only one person in this country left that knows that system inside and out. The only way that anyone would know that system would be from the information they learned from the countless hours spent on the phone with Pete.

    lockformer mad a real POS and sold a bunch of them and the few that still remain are nothing but a headache..

    This ismuch more than a DIY project . I had to learn by hard knocks and if I can save anyone the grief I will

    R_12

    I am in Cali, not sure where you are but I leave for work at 1:30 in the afternoon cali time. If you still cant get it to fire, leave me a message here and I will check back throuout the morning...do you know when the last time this thing worked was?

    What is the brand name?

    How big is it?

    You said this is a table, it is not a hand held torch is it?

    Is it a CNC?

    Automatic torch height sensing?



    Make sure you have all your gases turned on,also make sure you have a air supply.

    Is there a full time operator for this machine?
    If there is ask him, he should be able to help you alot.

    Let us know these answer.
    It will help getting to the problem.
