  1. Informative article thanks for sharing, it was a good read as I love two things the most, music and welding

  2. Highly informative Video
    Being a novice, i was confused about MIG welding like from where i should start learning this phenomenon. After watching this video a lot of my concepts have been cleared.

  3. Higher inductance smoothes the dot, fundamentally makes the puddle/dab wetter so it sets down better.Lower inductance has essentially the inverse impact, which prompts a higher dab profile and more slag.

  4. Nice article

    Jody A while back you asked about make the dime effect with a mig, I have a Miller 140 and a 250 both are about 25+ years old, and I have been able to do it by pulsing the trigger, a lot of the people I have worked with thoucht that I tig it together. Do you make a tig finger that two fingers will fit in ? Thank”s Frank

    Jody, I as always like all of your videos, and also am a customer for “Tig Fingers”, and videos/DVD’s. I very much liked this video, as a friend of mine I help at his fab shop, only uses 100% Co2 gas for his mig welder. I don’t know if his old Miller maching has an induction setting or not, but I’m going to show him this segment. When he welds, he gets multitudes of splatter/spatter. I’m always trying to get him to use 75/25 or 85/15, blend gasses. He is old school and has welded most all of his life, nut that doesen’t mean anything to me. We had welders at the refinery where I use to work before retirement, and yhey weren’t any better after 20+ years, than the 1st day they passed their 6″ schedule 80 tests on the Arkansas bell hold position. Thanks again for all of your expertice, and I especially like the “Cold Beer” breaks, Ha,Ha…………………..Brandy

      Jody,

      I work for a company that makes ash-handling equipment for coal-fired power plants and our wide range of products allows me to keep my MIG, TIG, and stick welding skills sharp; the bosses allow me the freedom to decide which process is best as each job comes through my work area. I use a Miller Invision 456MP with a dual-schedule wire feeder; we do a lot of work where carbon-to-carbon and carbon-to-stainless welding is performed on the same pieces and it’s REALLY convenient having 2 guns ready to do both applications at the pull of a trigger. The machine has a separate, adjustable inductance setting and, to be honest, I’ve never experimented with different settings; I just leave it at 100% all the time. We use .045 Metal Core MC6 wire with 90/10 Argon/CO2 gas for carbon welding and .045 308, 309 & 316 wires with 98/2 Argon/Oxygen gas for stainless. The majority of our material thickness is 1/4″ and up and, from what I saw in your video, my high inductance setting is ideal for me since I always set the machine to produce a nice, smooth spray transfer; I don’t stop adjusting my settings until I get that nice, quiet, spatterless spray that only goes from sizzle to crackle if I travel too slow or run over a tack. I’m currently fitting up a 316 stainless job and when it’s time for the welding, I’ll play with the inductance and I’ll come back here to share any results that are worth reporting.
      Your videos have helped me to expand my TIG skills with some adjustments to my technique and 2 TIG fingers that now save me a lot of positioning time. The TIG machine I use, by the way, is a 1970 350A AC/DC Miller with a water-cooler and a steel foot pedal that has air vents in it’s sides – it’s an antique beast and I love it but our welding inspector looks forward to “the repair bill that’s big enough to send it to it’s next life as a boat anchor”.
      Thanks for everything you’re doing with the videos; they’re very informative and refreshing. Of the other 15 fitter/welders I work with, you’re the first one I’ve come across with the same level of passion and skill for our craft.
      Jason
