help with fluxcore welding problem

I have purchased a new fluxcore mig welder and am
getting really bad welding results. The welds are very
crusty and lot's of weld splatter sticking to everything
metal. I have welded with a gas mig welder for years with none of these problems. I don't understand, is it a heat to wire speed issue or does fluxcore just not weld
very good?

-----------------------------------------------
make sure you are using the right polarity for the flux core wire you are using
..
almost all the flux core wires for small mig machines are designed to be used with dcen electrode negative..thats opposite from what bare wire needs...and so many times thats the problem

it will never run quite as smooth as bare wire with gas but it should do ok if things are set right.

thanks for posting,

jody

I dont see my last comment posted , however most of these fluxcore machines out of the box come with a generic elcheapo no name fluxcore which is probably causing excessive spatter and crappy results ...try some quality fluxcore to cure this Hope this helps !! Steve and mohhamad obviously didnt read your post correctly...
