Flux core welders

A couple of other things I forgot in my last post.

I am not sure of the terms here, but I have found some cheep mig/flux welders that the gun is always "hot" and others that the gun is only "hot" when the trigger is pulled and wire is feeding. The always hot type is a huge pain in the a$$ to work with. My campbell hausfeld mig-flux 105 is an always hot welder and it is very difficult to do "tiny tacks" with.

Tractor supply sells and "switches out" gas bottles for what seems to be a somewhat reasonable fee.
