Weldaid/ Lube-matic-pads are great. I sell a ton of it and the guys like the results. A new liner would likely help you. And both Lincoln and Miller have youtube tutorials that can help you a lot. I don't know where you are, but find an Airgas location near you. I can tell you where it is if you tell me where you are. We can hook you up with all the help and advice you need.
CO2 will be a dirtier weld. A lot more soot/smoke when welding. good for exhaust type work, not as good as 75/25 for body work or frame type steel. I take it you are welding indoors???

I'm not completely sure about the smaller welders but the contacts I mentioned should be the only moving part inside the welder when you hit the trigger the contacts close.Unplug the welder (obviously) and make sure they are not carbon arced or rusty, this is the power that melts the metal so it needs a solid "contact".Also a liner doesn't have to be kinked to "drag" the main reason for failed liners is gunk build up.If it set out the liner may be rusty or gunked up.I would check the liner, contacts and feed wheel before buying anything.You said only one feed wheel for .023-.035 wire.That should have two grooves one on each side.Unless it is V'ed that will scare the edges of the bigger wire.But if that's all there is use it just don't over tighten it on the small wire, it will try to pinch into the groove.

Kinda lost track here. Doug have you checked that the voltage is correct polarity? I believe mine was reversed for flux core, I seem to remember having to switch mine

You want the torch positive polarity, and the ground clamp neg. for shield gas
