Reply:Sure!  I have one.  Its a  century.  Power in, power out and a 110 volt plug for the box to make the hi freq.  I paid $200 for it.  About the size of a shoe box.  True hi freq.  It does not turn gas on or anything else.  Just a hi freq box.  $100 plus shipping  DavidReal world weldin.  When I grow up I want to be a tig weldor.
