We're going to do a sizing down on a 14-karat white gold ring.  Now my normal parameters are going to be 205 volts, four milliseconds, 0.6 millimeters, and three hertz, but that's going to just leave a surface weld but I want to get deeper down into this ring.  Now to do that I'm going to increase the voltage up to 240 volts.  A higher voltage is more heat and it's going to get a deeper penetration into the ring.  We want to do a lot of shots, go all the way around.  Now that is welded all the way completely through.  And I'm going to go back down to my 205 volts to add wire.  I'm going to be using my 30 gauge, I generally use 19 karat white, 30 gauge wire.  Go all the way around.  And a little bit.  Now I'm going to increase the beam size up to 0.9 millimeters from 0.6 and what this will do is it will smooth it out a little more.  When I smooth it out I just do a little left and right.  There we go.  We can do the v notch, it's what most people usually do.  And v notches are pretty easy because you can use your standard parameters, 250 volts.  Now I'm going to use my 14 karat yellow gold wire and I'll use a thicker wire to fill in these. Actually you should be using the zinc free.   And there we go.
