I assume your reference to Rick Welch's school means what does he recommend for an anchor? Rick would agree with Arne's last post, in that he would have you first learn to come to full draw without worrying about an anchor. You may need some help with this, if you're not quite sure what full draw means. Terry's form clock illustrates this very well, but seeing it and feeling it in your own body are two different things.
Once you can draw to full draw and hold, Rick would have someone put a mark on your arrow shaft opposite your nose. That would mark the location of the back of the cock feather. Once you mounted your feathers in that position, you would draw until the back of the cock feather touched your nose. As you shoot, you will become more comfortable with this anchor, and may decide that it should be a little more forward or backward, so it is a good idea not to fletch too many arrows until it settles in.
Then you would find an alternate anchor somewhere on your face, so you have two anchors. Rick recommends your thumb knuckle against your ear lobe for the second anchor, but everyone's face is different, and his second anchor might or might not work for you. But you should be able to find something on your face or jaw to touch with your thumb knuckle as a second anchor.
