  • Millermatic 211

    I was butt welding 3/8 steel and the only way to get penetration was to slow my travel speed. My settings where off the chart 8 heat 85 wire speed.
    The weld looked like crap and i had a high mound bead. This is max metal size so how would you handle this weld. I still have to weld overhead on the bottom of steel. I had scrap piece to practice with and the same result. Until i slowed my hand speed i wasn't getting penetration. When i went my normal speed the weld had porasity sp? I think i might have found problem i was using 030 wire miller says 035 think this is problem?

      Is that an Inverter model? If so the highest setting is 10 and that is where it should be for 3/8"..........Do you have that plugged into 220volts? Slow the feed down some if the wire is building up............last resort is to pre-heat your parts.

          Not enough info to make a good decision I think. <br />

          Sometimes, turning your wire speed down is the wrong way. You need some wire speed to punch that arc in there, that's how you increase the amps in your weld puddle. It may sound backward, but it's true. Lots of good YouTube videos about it. <br />

          Check out weldingtipsandtricks.com and go to the MIG section, watch some of Jody's videos and it will make you happy.

            That's how the old manuals were printed before all of the fancy smancy digital screens. Bang the big lever close and fine tune it up with the wire speed...

                      Very good question. Especially the welds near the bottom look like the shielding gas was AWOL.

                        Good thought Bob....

                        looks like a gas starvation/corruption problem....

                        or maybe air getting into the molten arc puddle
