Reply:We need a pulling teeth smiley. Machine, voltage and wire speed, wire size, gas used and flow rate or FC, material thickness position if not flat.... I think we've gone thru this before... When you want us to judge welds we need ALL this information, usually every time so we know what it is. we seldom get too muck info.I can be as simple as Millermatic185, Tap 4, .030 solid wire, wire speed 45, C25 gas 15 CFH, 1/8" steel vertical lap. If the machine is dual voltage like the MM211, you'd also want to include if you are running on 110v power or 230v power.Just a picture doesn't tell the whole story. What works on 1/8" won't work for 16 ga or 1/2".Do yourself a favor and buy yourself a small work light to illuminate your pieces so the picts are better and you don't have to use the flash. It can be one of those small halogen work lights or one of those cheap clamp on flood light holders. With a phone you are very limited taking picts also. A semi decent digital camera will open up a lot more options for better picts as well..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.

Reply:miller 200 wire speed was 30 I do not know the voltage though   75% argon 25% co2  .  Im still learning all of it in class. im trying to learn and get better at all of the tig, stick, mig, oxy/ace.   I just been using a dewalt flashlight.Lincoln 140 Pak MIG Everlast powerarc 140 STLincoln Tombstone
Reply:To slow, pick up your travel speed a little.Some kind of Big Blue constant current welding machineAnother smaller yet, Blue machine (it's got wire in it)

Reply:1st and last picts aren't bad. Others are fair, but better than some of the originals. One issue with a light source like a flashlight or even a flash, some times is that many cameras auto adjust based on the brightest area. That means the areas not well lit go really dark and you get a lot of shadows and high contrast that makes the beads often look worse than they might be, or they hide details. Last pict of your 1st group is a good example of this.Last picture the bead on the left looks too slow. Consistency is better on the left vs the right. Right bead looks a bit wide, but the toes are better than the one on the left. I'm still guessing at material thickness and with nothing to use as a reference it's tough to tell. Therefore it's tough to tell if the bead really is too wide, or the other one is really too small. I'm guessing this is on 1/4" plate by looking at pict 1. I'd be tempted to tell you to up the voltage at least one tap from what you are running..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.

Reply:Grind the mill scale off then use a piece of soapstone and draw 6 straight lines on the piece to follow as you weld. MIG doesn't like mill scale.Millermatic 200Hobart Handler 120Victor O/A & Ramco BandsawLincoln 225 ACSnapOn AD HoodMiller XMT304/22AHypertherm Powermax 1650 G3Lincoln Idealarc DC600 w/Extreme 12 VSMiller Digital Elite "Joker"

Reply:Are you using a fluxcore wire, or are you using solid wire with shielding gas?Reason I ask is that if you're using solid wire you either don't have the gas turned on, are out of gas, or some other reason there's so much spatter.The Lincoln instructional - trouble shooting mig welding - posted by Duane above is a good little tape to watch, or type "troubleshoot mig" or "mig weld problems" or something like those into YOU-Tube and be ready to spend an afternoon watching short videos. They can help a binch and in many ways make it easier to learn than being in a school, IMO. You can pick and choose and there's no tests to worry over.
