Jack,
I do not have a Wasp .061, but since it is a near copy of the Big Mig I would guess that it fits. You can also use a Cox glow head or better yet, you can get a Galbreath adapter that uses a Nelson plug, or an adapter that uses a "turbo" plug.
The Galbreath/Nelson setup can be ordered from "Kitting It Together", and seems to be the most popular setup.
