I would appreciate someone directing me to a downloadable guide for setting up my machine. Need help with gas flow, wire feed speed, travel speed, etc. Using CO2, 0.023 wire. Running practice beads and welding coupons on 3/32" mild steel. Beads look terrible. Been stick welding for years but need help with MIG.Don't have any pics to post.
Reply:The machine should have a set of suggested settings under the cover that will get you close. Here's a link to the MM130XP. Pg 16 lists suggested settings that should be close to what you need. 14 ga would be roughly 3/32". You may have to bump up the voltage to tap 4 if you are running on limited input power.Note that under real world conditions, 1/8" is about the max you can expect to do well with that machine despite what Millers literature says. Expect to reduce that max thickness if you aren't running on a dedicated 20 amp outlet or if you are using an extension cord.http://www.millerwelds.com/om/o1316f_mil.pdfPost up picts of your welds along with the settings you are using and we can help you improve..No government ever voluntarily reduces itself in size.

Reply:Thanks DSW. I quickly read the manual. Will follow up and respond after I try a few things (going to experiment with thinner metal first). It will most likely be a week or more. James
Reply:100% CO2 has a few good and bad sides. It gives you more penetration, so once you go thinner than say 18 ga, things start to get harder compared to running 75/25 gas. This helps with "thicker material" in comparison to 75/25 however. You also get more spatter with 100% CO2, so there is more clean up, but gas cost is cheaper....No government ever voluntarily reduces itself in size.
