    Yeah red beard is back. And dont be afraid of taking gas shielded outside. We do it all the time. It can be quite windy outside. As long as you stand with the wind at your back and cover with your body. We use the Kemppi evo 200 one phase machine and run 1 mm 0.0394 3/64 ″ wire. Now Kemppi has the new evo 220amp one phase This can run 1.2mm wire

      But as long as there isn’t a breeze of wind i love it. If you set the machine right you climb 30 feet in the air and weld in every position and not have to worry about setting the machine for different welds. It saves a ton of time and climbing

    I use gas shield flux core exclusively, and I love it because it’s so easy. I’ve bent tested and cut-and-polish tested a bunch of my welds and they’re rock solid. And I use a Yeswelder so it’s not high end equipment. It’s probably the most versatile process for the guy who wants to weld steel at home.

    Dual Shield. The flux is essentially a heavy deoxidizing agent that rips through millscale like nobody's business, floating it to the top in the slag (which slag also helps support the puddle out of position.) Shield 1.
    Shield 2, keep the atmosphere from destroying the weld. The flux isn't designed to do that; that's where the gas shielding comes in.
    Dual shield.

  • @katanamaki9015
    @katanamaki9015 2 місяці тому

    I ran gas shielded flux core in the shops for years. The flux in dual shield is for higher deposition and also contains cleaning agents to help lift impurities to the surface where they can be removed with the slag. Selfshielding flux core is mostly used in the field due to its resistance to breeze or wind. I have also found with the polarity being DCEN there seems to be a little less heat produced in the gun for the wire size. I use 0.045 gassless flux core at home with my 200A lincoln and a suitcase feeder with little issue. Once I moved to 0.045 C25 shielded wire the gun got noticeably warmer quicker. To the point I had to stop and let it cool. Never was an issue with gassless flux core.

    Haven't commented in some time as my health tends to tell me when or not to do stuff. I have straight up envy of your table. I am pushing seventy five right soon and just wish we had tools and machines like this in the sixties and even up to eighties. I really don't know when these new machines came to be but golly whiz, nice welds and little efforts for nice looking great welds. Other day I seen my landlord trying to use a torch and couldn't keep my trap shut. He blows off at me and said if you can do better then hop to it. I told him to hang onto my suspenders so I don't get to be a part of it. He had metal starting to warp and nasty looking jagged looking cuts going. He also had been at it for around fifteen minutes and was getting nowhere fast. It took me more time to clean the tip, do a little prep and then slick as a whistle sliced off the offending metal he was messing up. My cut looked like a plasma cut and no slag, just straight and sweet! He looks at me and just shook his head, where did you learn all this? Oh about forty some years ago we had to buy oxygen and acetylene plus it came from the main land so getting tanks out on a job site was right expensive. Best learn quick or learn how to use a hack saw..... he is now asking me to teach him. I just wish tho I had a better memory as I have seen the newer welders that have a great many functions that are right at the fingertips.

    Dualshield is an ESAB trade-name that refers to the ability to use either Argon/CO2 or 100% CO2. The gas provides the shielding and allows for a long, high voltage spray-arc that gives low-spatter high-deposition with a very fluid weld that is held in position and shaped by the slag-covering which is the primary reason for having the flux. So; gas for shielding, flux for shaping.

  • @Kurokimachine
    @Kurokimachine Місяць тому

    We run Bohler fcaw-g wire here with great results. I am a big fan of selecting a wire that runs in 100% co2. One thing often overlooked by welders is just how much cheaper co2 is. What my company pays anyways, co2 is around half the price per cylinder of c25. But on top of that being stored as a liquid the same size cylinder holds roughly double the volume of co2 vs c25. So really your cost is about 1/4.
    I think a lot more people would run 100% co2 if they realized that.

    The only things I gotta say yall missed was 1) when he asked about the first pass on the 1/2" plate, Jason shouldve told him to turn the volts up. 2) running gas on self shielded wire is not only wasting gas, it might be detrimental to the strength of the weld. The alloys and deoxydizers in the flux werent designed to have shielding gas, so they're fighting that additional unnecessary contamination.

    Another reason for the gas-shielding in dual shield wire is the arc will cause the gas to ionize across the arc stream giving you a “hotter”, higher penetrating arc.

      I worked for a steel boat company and they were stick all the way. I was an electrician but welded my own racks. I asked the owner why he hadn't gone mig as it was far better in production than stick swapping. Checked in on him a couple years later and he had included MIG. Seemed to improve construction a bit. Can't use it in small spaces and backside of pipes in corners, but it was a big plus on hull and stringers. (Especially on the 100'+ boats)

    The flux in dual shield facilitates running out of position as the slag actually freezes before the molten weld pool. Also, I’m guessing, the flux contains iron powder therefore increasing deposition rates. I run a ton of it and always say that if you can’t run vertical up and overhead with dual shield, you better find a new profession.

      Cooling of torch is just an exstra bennefit of the cold gas. But main reason is to protect weld against oxygen. But the gas also affects penetration. The slag helps to suck out Contaminants from the weld. And it works as a mold when you do position welds.

    Would you take your MIG welder outside in a 10mi./ hr cross wind? Dual sheid doesn't fair any better. It's indoor, "structural MIG" welding. It's almost as expensive as TIG welding. The absence of freeze lines makes it difficult for you to analyze your mistakes. The bead looks like a slug. Just learn SMAW and MIG, keep it simple. Don't waste your money unless your in business with a shop.

      We do alot of welding outside using dual shield. Of course not when the wind is hurricane force.
      But as long as you manage to position yourself so that the wind is at your back, it can withstand an incredible amount of wind. I prefer to weld with wire rather than electrodes.
