Thread: Diesel generator recommendations for PowerTIG 255EXT

  1. Default Diesel generator recommendations for PowerTIG 255EXT

    Can anyone make recommendations for a diesel generator capable of powering the PowerTIG 255EXT efficiently?
    Just trying to explore some options for my next endeavour.

    (Wow it's been a while since I've been on here)

    You might want to specify which version you have, as the later model added power factor correction which will make it a lot easier to run on a genset.

    Didn't realize there would be a difference.
    Either way.
    2016/2017 model.
    Don't own one yet.
    Looking to purchase before the end of 2016 providing I can find a genset to accompany it.

    I just don't know enough about generators and running welders off generators to make my own call.

    I would have thought Everlast has their own generators to accompany them.

    Nothing?...........

    From the PowerTIG255EXT manual:

    Minimum Generator Requirement*
    8500 Continuous Watts
    * Generator must be certified as a clean power unit by its manufacturer with less than 10% total harmonic distortion.

    I would look at a 10kW or greater unit. Especially if you want to run some tools off of it.

    That's the problem. Finding anything above 10kw that's "clean energy/power/pure sine wave" etc
    I'm not really finding much that advertises that they are (10kw and above anyway)

    Most of the small diesels I've seen are more for grunt power and advise not to run electronics on them. No problems with the big ones, but not what you are looking for. There are some larger RV type units, but the prices on those might be more than you want to spend.
    In gasoline power you have a lot more options.

    I ran a 15kw diesel Kubota generator with no problems on very sensitive electronics, but it was costly. I can't remember the brand of generator attached.

    You might give these guys a call: http://www.hardydiesel.com they sell a variety of diesel generators. These are industrial generators, I would be surprised if they did not meet 10% or lower THD specs.

    Basically I'm looking the cost of a diesel genset that can run inverters vs the cost of a engine-driven diesel welder that can run interters. Namely the Trailblazer 325 diesel from Miller which states it can run their Dynasty series inverter TIGs.

    The cost of which will run me $12k Canadian. But I don't really need or want the welding portion of it. I'd rather have a dedicated genset capable of running a 255EXT off of it rather effortlessly.

    So my budget is right around there... Give or take.

    I'm finding that a lot of websites don't list THD, but rather just "voltage regulation" which I'm not sure if that's the same thing or not.
    I've found a couple 15k gensets that claim a voltage regulation of 1%-5% but I don't know if that's the same a THD.

    In that range you should be able to find something. While voltage regulation and total harmonic distortion are very different, typically they will both improve together in better quality equipment. Any of the high end RV generators that are made to run electronics would power a welder with no problem. If you want quiet, that will raise the price, too.

    Here is a good read http://www.backwoodshome.com/dont-di...-power-source/.

    The liquid cooled and quiet struck me. I know my old Onan was good but loud and heck.. After this thread, off to check the 125Kw

    THD is NOT the same as voltage regulation

    That is why I suggested to give them a call. For instance, the Leroy - Somer TAL 04​​​0 lists the following:

    Voltage regulation (Steady state) ± 1%
    Total Harmonic distortion THD no load < 3.5 % - on load < 5 %

    http://www.emersonindustrial.com/en-...es/TAL040.aspx

    I found several industrial class generators on their site that are less than 5% THD

    I received an e-mail from a company here in Canada to which I'll summerize.

    "Thanks for your email.

    Our generator heads provide less than 1.5% THD (Total Harmonic Distortion) and the AVR's (Automatic Voltage Regulator) for the 13kW and 20kW is less than .5% + -

    I hope this helps."

    This seems to be inline with what I require, no?

    Yes, those are very good specs.

    Is it safe to assume that if it can run an inverter type welder that it would also be safe to run a PC?
    Probably a silly question.

    Yes you could.
    When that company said "generator heads" They're not giving you the information you need. They are referring to the capability of the generator head itself and not the output when driven by any old internal combustion engine.
    The engine itself will introduce harmonic distortion... some more than others.
