nozzle need for flux core MIG?

go to see Welding Machine for nozzle need for flux core MIG?

I'm brand new to welding (attempting to weld  ). I'm trying to get a loaner 110V marquette welder up and running.So far I havent been able to even lay a bead down without splatter and BBs all over the place. just trying to lay a bead on 1/16" steel sheet metal.I noticed that there was no nozzle on the gun. Just the replaceable lincoln tip that you buy 10 to a pack at lowes/HD. Is a nozzle a necessity? what purpose does the nozzle server? Ive seen some pictures where the tip is actually flush with the tip. Should it be flush or protruding out a bit over the tip?thanks
Reply:No gas nozzle needed (or even desired) with self shield fluxcore wire.  The purpose of the gas nozzle is to direct the shielding gas over the weld.  You can see why it's not needed with gas-less wire.  This is, of course, is assuming your particular torch doesn't require a nozzle to keep the tip in place.  Some torch designs require it.  If not, toss the nozzle and have fun with your fluxcore welding.  MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:its flux core dont worry about it i use one either with mine. slow down your wire speed it might be trying to burn to much wire so its not heating  the metal to create the pool
Reply:thanks for the replies folks.after watching a couple of other vids that show the speeds of the flux core feed, i think this welder might not be feeding right. at its highest fastest setting its nowhere near the speed of some of these other 110V machines
Reply:When I was at the LWS looking for regulator parts (I've got flux core now in my used welder),  The guy suggested that I try the fluxcore without the nozzle to get a better eye on the puddle... . I haven't tried it yet.....  I use nozzle gel on the nozzle to make spatter easier to remove.P
Reply:some units use an insulated nozzle to isolate the contact tip from the work.
