the only thing i've found with the little wire feed migs, when you're going gas-less with the flux-core wire, it spatters a bit and you end up with a bunch of "acne" around your weld. Try using a little squirt of spatter-shield spray before you lay the weld in... makes the little spatter balls roll off. otherwise, the balls stick, giving you extra work to clean up. Other than that, these little welders ARE very easy to use, and do a hell of a job!!! I think even home depot sells SPATTER SHIELD, or you can ask for it at your local welding supply shop.
