Attach an emitter to a weapon

[HaTeMe]

So, I want to attach an emitter to a weapon while you are holding it. Any idea how to achieve this? I know how to spawn an emitter when the weapon fires etc but I need it to spawn a looping emitter on the weapon itself while its not being used but you are just holding it.

At first I thought the small flame at the end of the flamer might have been an emitter but looks like its just a texture or something...
