Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 The good stuff It was always to pricey for me. But when I was in shops that used only Lincoln you could smell the difference.

Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 Originally Posted by Willie B I get confused at the sea of numbers. Is this actually gas shielded? Or is it non shielded flux core? The class of wire that you should look for is E70T-1, E71T-1, for 70ksi wires for the basic type. Those are gas-shielded flux core wires. Gasless flux core wires are usually E71T-GS or E71T-11. Not all FCAW-G are 70ksi rated nor of the same family/class, however. There are others, which will start with an "E" can then be cross referenced
Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 I run 71A85 on heavy equipment repair. I love it. It is stupid easy, in any position or direction.

Attachment 1739387 It is Dual shield. Gas shielded flux cored wire. Even says it right on the spool. I use Lincoln 71A75 - 1/16" W/100% CO2. I also use Lincoln 1/16" - 232 and 233 Inner shield Flux core.
Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 The Kiswel I've been using does require gas. I use it with 75/25. Maine OXY wanted about $250 for that roll of ultracore that you have
Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 Originally Posted by ArcTan I have been using Kiswel E71T-M from Amazon.

But I haven't tried any other dual shield wire so I have nothing the compare it to. Attachment 1739386 I get confused at the sea of numbers. Is this actually gas shielded?

Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 Have found the contamination to be a minor inconvenience as well. Didn't want to mention it as it may have been lucky...not 6010 like but pretty tolerant

Haven’t found much information on that. I've run .035" gas shielded wire on several 180-200 amp mig welders and it runs good on 1/8" to about 1/4" material. I've used it on dock leveling plates, staircases, cardboard compactors, truck dock bumpers, dumpsters, etc. Most of the time I've used it outside with straight CO2 mostly, and sometimes 75/25. They have all held up, even the ones done outdoors ( I bump the gas up a few CFH ) I prefer it on repair work because it burns in hot, works well in all positions, and seems to be more tolerant of some contamination. To me it seems like 7018 on a roll. It is a little bit difficult to find in 10# rolls from some distributors, and it costs a little more. If you really need it, it's worth the extra effort and price. Try some , you might like it. Good Luck
Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 Attachment 1739375 That's a pretty horizontal welded with ESAB Dual Shield welding by two shifts. 9 inches thick with cooper heat keeping it at around 350 deg f. I kept trying to stack it in vertical but the day welders kept sloping it.
Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 Should run but it is probably sort of in the low end of the parameters. If the machine runs .035 bare wire well it should do fine with .035 dual shield. I ran a lot of bare wire before running the dual shield and i think it's easier to run particularly for out of position work but there is a learning curve and a few rules like verticals must be run uphill and don't let the flux get ahead of the puddle.

Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 Thanks for my use because it can be pretty sporadic storage is an important consideration so the 10-15 pound spools are best. I know for work welding large verticals I got it set to run nice fat stringers really clean a well tied in.
Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 That second video nails it on the vertical stringer and the cross section cut show it well, he also shows exactly what's up with the worm tracks when they show up shave a bit of voltage. We had tapered nozzles for doing root passes which helped too.
Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 I started using in 1980 for shop work E71T-1 w/CO2. It replaced E7018 for all shop welding. If everything is right the flux will peal off after cooling. Dave Originally Posted by NotaVegetarian Wow great thread didn’t know you could do that
Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 I agree 👍 Dave Originally Posted by Louie1961 Yeah, dual shield flux core is a great tool for a wire feed welder, especially for heavier material and out of position stuff. It has weld qualities as good as or better than 7018 welding rod, but without having to change rods every 8-12 inches, and it is much easier to run vertical up and overhead than 7018. The 035 wire extends the range/capability of 175-200 amp consumer grade MIG welding machines quite a bit for thick stuff

Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 The Esab website has pretty good descriptions on what wires work with what gasses . If I remember they have plenty of choices in the dual shield category. Have run .045 in co2 with esab 7100 in MM200 with good results.

Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 I had a terrible time with 71A85 using 75% argon. I finally used up the roll & replaced it. The guy at Maine Oxy said it won't work with 75% gas He sold me Lincoln 71A75 & I've had a much better experience.Attachment 1739319Attachment 1739319 Damn, I can't make it vertical in the photo.
Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 Thanks, a lot of useful replies! The fabrication work i anticipate is not very demanding but it's good to have all the opinions on the gas shielded flux core. I will try the Lincoln UltraCore® 71A85 wire first just because Lincoln has done so much for American Arc Welding education. I feel the millermatic 200 will push .045 ok for my needs but i will find out.
Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 I've run the Blue Demon 71M on Argon/CO2, and just 100% CO2 in both the .035", and .045" sizes. Both sizes ran well on both my inverter mig, and my transformer mig machine. I ususally get it from Mcmaster-Carr in the 10 lb spool. Some people don't like it , not sure why. I've also run the Praxair store brand wire, which ran well also. Even the really cheap-o stuff (welders choice) from MSCDirect ran well for me. I've only run one spool of lincoln .035" but I don't remember the exact number, seemed to weld the same as the others. My biggest problem with wire is storage. I'll wind up with half a roll leftover, and it will go bad out in my garage by the next time I need it (corrosion). I keep meaning to put it in a ziplok bag with a dessicant pack, but sadly, I hardly ever do. good luck
Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 That MM200 will do fine with .045 dual shield. Bonus with the 75/25 gas is less voltage is required to run it. The downfall to 75/25 is that it doesn't have the same cooling effect regarding duty cycle on the mig gun as CO2 has more effective cooling.
Re: Gas shielded flux core wire choices for Argon/Co2 75-25 in .045 Originally Posted by Eelspike I know the MM 200 is under gunned but the .045 with the core probably has about the same metal as .035 bare wire. The Lincoln comes in smaller spools so that's attractive to start. It the same with the Co2 I would just as soon deal with the C25 that have to get Co2. Not looking to do real production and if that becomes important I would get a bigger inverter setup. Have 300 amp stick and tig capacity already. Either way you are making a good choice. The 71M can run with either 100% CO2 or 75/25 and actually comes in the small 11 lb spools in both 035 and 045, just so you know. Dual shield is my favorite if I have to run out of position.
