basic guidelines for setting voltage and wire speed for mig?

admin

I know with tig its something like 1 amp for every .001" of material thickness I'm looking for a basic way to figure out which voltage to set the machine to and then whatever wire speed works with that voltage if say a piece of XX" metal were thrown at me
Reply:Most smaller machines have a chart that is usually under the door that lists sugested settings for various thicknesses. Here's the chart from Miller on the MM252. It's on pg 22 section 4-17 and lists the settings in volts and wire speed rather than some of the other machines that list it by tap number.http://www.millerwelds.com/om/o230693k_mil.pdfLincoln has a chart on pg 67  near the end of this PDF that will give you some of these parameters as well.http://content.lincolnelectric.com/p...ture/c4200.pdfHere's another table from Essab that has some of that info. It's a bit hard to read on the screen, but you can print it if needed.http://www.esabna.com/EUWeb/MIG_handbook/592mig12_8.htmBoth Lincoln and Essab have a lot of good material burried in their web sites on fillers. With Lincoln usually you need to pick a filler and then pull up the guides and pdf's and go thru them to see if theres a chart that covers what you want. I haven't had the time to dig thru Essabs site too much, but every time I do I find more good info burried there..No government ever voluntarily reduces itself in size.
