    Default Line low voltage for econotig

    Working overseas in construction site sometimes get bizzars

    At pulp and paper plant site construction that do not have a standard electrical supply, some unusual solutions as to be implemented.

    The available electrical temporary (ac gas gen) does not gave more than 190 volts for the contractors and in my case a two Econotig have to be fed.

    Initially each Econotig (230V) was supplied by the temporary supply, resulting not running well.
    The solution was install a 220/40volts 600VA(nominal) transformer (from junk box) in each Econotig. The connection is auto transformer connection, so the line voltage 190 was transformed to 35 volts and then added to the line voltage, resulting in 225 volts.

    In details:
    The line (190V) was connected to the 2 transformer primary leads.
    One of the transformer secondary lead connected to one of the primary lead.
    The other transformer lead and other secondary lead connected to supply the cord of the Econotig.
    Resulting line voltage(190V) added to the secondary (35V) = 225V that fed the Econotig.

    The transformer was bolted in the back of the machine, achieving a monoblock assembling allowing both go up and down easily.
    For more than six month, 6-8 hours a day the two Econotig worked well.

    Do somebody knows other solution that can be suitable for the case ?? If so, let me know.

    Yes, the autotransformer insulation is class F. But it does not warm up too much.

    This is common and just accepted by the contractors?

    A few things come to mind. Miller Maxstars or Dynasties wouldn't care about the lower voltage and would automatically compensate with their Autoline technology.

    Can you bring your own generator?

    I don't exactly understand what your poll is asking for.

    Do they even know, or just not care, that they are providing substandard power and still wanting people to use it to work for them?

    The poll makes no sense to me either......sorry.

    With low line voltage I'd try for an inverter machine.

    Absoulutly no idea on the poll, however a inverter is a much better choice in your situation.
