    Fuse checked out ok, but just remembered that when the operator started welding the motor laboured and I don't think it idled up. I'm looking into this as with no idle up he wouldn't have the rpm to produce the voltage needed. Thanks for the help so far guys.

    How did it go when You checked the fuses I don't know how to check the hertz but I check mine with tiny tac for rpm and the elec plugs for close to 120 volts with a meter

    Pop the top cover, under it you'll see a couple fuses, Check F1, its likely blown.

    also check engine RPM, its checked via the auxillary terminals in Hertz on your meter. That engine must be running in at 62.5 hz

    Bobcat 225 NT

    Hello All
    I'm new to the forum and am hoping someone can help me out.
    We have a Bobcat 225NT that we're having a problem with. The operator complained of low output. I metered across the output studs and get 47v open circuit voltage. When he strikes an arc it immediately drops to 20v or less. I can adjust through the ranges and bring up his ocv but the output is relative and about half of the ocv. Any help would be appreciated.
Working...
