Ballast



Original poster: "Chip Ford" <chipford@xxxxxxxxxxxx>

O.K. I have found a pic of a ballast diagram. I can see in this diagram that it is wired in series with (1) leg of the 240 ac feeding the input transformer. Is this the normal configuration? Or should one ballast both legs? Also what is the talk about running the welder leads in the open curcuit. I guess that shorting these leads will increase the ballasting effects of the transformer. I have welded quite a bit with a buzz box. I can remember the change in the sound of the transformer when an arc was present compared to when it was not. So I am lead to believe that when you ballast with a transformer, You only use one set of the windings. the secondary leads can be left open, shorted, or have a load connected between them. A resistor perhaps??? Am I correct. I can't quite wrap my head around what it will take for me to determine the amount of ballast I will require...Let's keep talking...
