flux core mig with gas?

admin

never tried this but was wondering if i used flux core wire in my mig with c25 gas if i could get better penetration on a low amp machine. century 90 amp mig. presently use 035 with stargon mix. welds about 1/8 to 3/16 max.
Reply:FCAW wire is designed to be a hotter burning wire and made for deep penetration. Are you not comfortable with your welds on 3/16? Have you tried beveling the material? I'm not sure you would benefit but you could always give it a try.John -  fabricator extraordinaire, car nut!-  bleeding Miller blue! http://www.weldfabzone.com
Reply:I think i read some where there is whats called dual sheilde wire.Its got a smaller amount of flux built in the wire. But has a it need a gas sheild as well.I might be wrong.
Reply:Their is a gas shielded flux core wire, I believe its called T91. This type of wire and gas combination is used when you are looking for a mig weld equivalent of a 7018 rod arc weld process. it does give a xray weld quality.I do not know what the weld would be like with just regular flux core wire using shielding gas at the same time. I think that you might be better off getting the proper wire for this process and see how it works.Miller DVI2Lincoln Precision Tig 225Thermodynamics Cutmaster 38Everything else needed.
Reply:All of the major manufacturers produce many different gas shielded flux core wires.  You need only to go to your local welding supply and ask the nice employees which particular wire they would reccommend for that gas mix.  Self-shielding is called "self-shielding" for a reason....it is not meant to run with gas.  You will not get better welds by using gas with self shielding wire.   Oh, dhardin53, there is not a "smaller amount of flux" in the gas shielded wire, just different ingredients
Reply:makes sence to me.I thought the vew time i use dual sheild (gas and some flux in the wire) that the matieral built up faster. Thats the only reaosn i thought it had more metal per inch is all, granted not very much.Thanks for the info.

Reply:thanx for all the input,i've never tried the flux core with gas,have welded dual shield a couple of times[welds really hot but looks awesome]just wondered b/c don't have the moolah right now for a better machine.my welder can weld 3/16 with beveling but the penetration's just not there,it helps if you heat the piece up with your torch first but that's kind of jake for something i'm trying to make really strong.
