  1. Rectifiers for Charger 5 Star Review

    Posted by on 22nd Jul 2016

    Even thought these rectifiers were listed as a welder part, were the exact same part/ part number of the
    rectifiers need for a Hobart Industrial battery charger.
    installed easy, worked as should.

    Thanks for the part, and excellent delivery .

  2. Hobart Handler model 6969 diodes 5 Star Review

    Posted by on 7th Dec 2015

    Physically, these diodes are the replacement for the originals, which had a -001 suffix. The solder holes are about .020" smaller in diameter, so really clean up your leads before attaching and soldering. Probably best to make sure your fan motor is in good shape, too. If your Gal-90 gas cone is shorted to the electrode, this is probably what blew the original diodes.

  3. diodes for vintage hobart handler 120 5 Star Review

    Posted by on 16th Sep 2013

    I knew my welder was running rough and looked at throwing it out. I then bought these as a last resort and Wow it works like 20 years ago I also replaced the 53000 uf capacitor. The wire feed no longer studders and has so much more heat penetration when welding I recommend this to any poorly running welder. 1 hour install time
