I recently purchased my XMT304 CC/CV and am looking to add either the 12vs or the 12rc Suitcase feeder. Is there a difference between them as far as welding characteristics? This unit is just for my home projects, nothing structural or code. I like the 12vs because it does not need a control cable but some people have said that the arc is different. Which feeder would be better for my application. Thanks, Chris
