    Tried flux cored wire on my lincoln 135 and it welded horribly. I reversed the polarity like indicated but the weld just did not hold up. I could take a hammer and bust the pieces apart ever time with ease. I have had no problems with using stardard wire and gas but thought it ould be easier not having to drag a tank of gas around with me. Any ideas what my problem could be?

    I had the thing cranked as hot as it would go. It spattered and was an ugly weld not mention that it didn't penetrate the steel at all. The standard wire and gas works great, just curious why the flux cored didn't.

    Was this a new roll? It's possible that the wire could be dirty. Check the contact tip in the gun, it may be worn. Is the wire the same size as what you were running before? Never ran fluc core but these are some things to check when there are problems.

    Flux cored wire is all I use and have never had this problem. I use .035 sized wire and have welded alot of things with it and they have always stood up. No idea on your problem but am curios on what it might be.

    ??? DOnt turn it up all the way.. Look under the cover to set the dials and speed correctly for the steel you are welding.. The setting s are diff for gas and innershield.. I just got the same Lincoln 135 and am using .o35" wire and it s' making awsome welds for me... very little spatter.. You have to reverse the roller, reverse the polarity and also change the contact tip if it's not already .o35" , your also supposed to use a diff insulator tip but it was? I just didnt like it cause the arc was all out in the open and I was used to seeing the big tip thing around the contact tip , so I left the gas one on anyway.. But It is making awsome welds for me.... hey are you getting close enough ? or too close , your supposed to keep the tip about a 1/2" to 3/8" from the work ? I noticed when I varied that distance it made alot of spatter and crappy welds..

    keep it close, hot and maybe slow it down a little!!!

    that welder should produce great welds flux or not........

    Thanks for all your replies guys. I converted back to gas for the time being because I need to weld up something up in an emergency and had no time for experimentation. I did reverse the polarity and change the tip. Maybe I just need some more practice. When I went back to gas it welded like a dream.

    P.S. Do you find that the flux cored wire emits much more fumes? I found that I had massive headaches after welding with it.
