Flux core is a different animal. It is useful if you learn its drawbacks. Here is a page on my website about it.

Long story short
- be sure you are runing it DCEN if it is gassless wire (electrode on negative)
- Use a long stickout (3/4 to 1 inch between end of contact tip and metal) this preheats the core
- You do not need the nozzle with gassless flux.
- use side to side (weaving) motion do NOT back up and weld over the slag
- voltage = weld width
- wire speed = penetration + filler
this is true on all wire welders
