MIG Welding (GMAW)
MIG (Metal Inert Gas) welding is a type of Gas Metal Arc Welding. It is currently the most common industrial welding process.
A semi-automatic or automatic arc welding process, it uses a continuous and consumable wire electrode and a shielding gas that are fed through a welding gun. It also uses constant voltage, which is usually DC, but AC can be used.
Kevin uses a Miller 251 MIG welder in his studio ("Murph") to create much of his contemporary art sculpture.

How to Use MIG Pulse Controls to Fill Gaps May 02, 2012 Kevin shows how using pulse control on his Longevity MigWeld 250P MIG welder helps him fill gaps in his steel sculpture Wherever You Go, There You Are without blowing holes in the metal because it gets too hot. The lower temperature lets him get a longer, cleaner weld. The ability to control the pulse width and frequency helps him get just the right temperature while increased wire feed helps fill the gap. |

How to Use a Spool Gun on a MIG Welder Apr 18, 2012 Kevin is putting the finishing touches on his public art sculpture The Seed and needs to add some tabs for installing the "kernel" of the seed. It's time to get out the Miller 251 MIG welder with the spool gun attachment for welding with aluminum. He shows the parts of the gun and explains how it works, then fires it up and welds on one of the tabs. |

How to Use a Longevity MIG Welder With Pulse Control Feb 01, 2012 Kevin shows the controls on the new Longevity MigWeld 250P MIG welder and explains how to use them. He also shows why the wire feed on the Longevity is superior and how to use pulse control to weld thin metals. Learn more about the MigWeld 250P at the Longevity Web site.

Choosing a Welder: MIG, TIG, Arc or Oxygen-Acetylene? Aug 17, 2011 Kevin explains how he decides which welder to use: his MIG welder, TIG welder, arc welder or oxygen-acetylene welder based on what sort of sculpture he's working on and, of course, what's most fun. |

MIG Welding: Using a Magnetic Ground Apr 07, 2010 When Kevin's ground clamp on his MIG welder melted, rather than replace it with another clamp, he opted for one of the new magnetic grounds. The rare earth magnet makes it easy to get a good ground wherever you?re welding. |

Following the Bubble While MIG Welding Mar 25, 2010 Whether you call it a "bubble," "dot" or "spot," watching the top of the weld as it cools and keeping it equidistant from the tip of the welder as you advance helps you create a great weld. |

MIG Welding: Should You Push or Lead the Puddle? Aug 26, 2009 A viewer of Kevin's TIG Welding Technique video said that, when he is MIG welding, he prefers to push the puddle, rather than lead it. Kevin takes on the challenge, showing how each approach works. You'll see some close ups of some pretty welds .... |
