  • Old Hobart Welder/Generator Info Needed

    Hello all,
    I recently acquired this old Hobart welder.
    Model: GPB 258
    Serial: 12CW22867
    Can anyone tell me the year of this machine? Is there a manual around for it? Any info would be great.
    Thanks

    Your unit was built July 1961. Check your email for manuals.

      One old time welder told me the DC output on these generator units is smoother than on single or 3 phase transformer welders due to the low ripple current. This being a function of the a 32 or so segment commutator. Guess a new inverter type unit could in theory be as smooth or better. I have a large shunt that I want to install on the unit for a welding current meter. There are two cover plates on the control panel that look like they might accept a round amp meter. I need to check ebay for a ruggedized weather tight MA meter that will fit. Your unit looks to have similar covers on the control panel.

        Keith, can you resend me the G258 manual again please. I thought I saved it but didn’t and I cleaned out my emails.
        Thanks
