miller wire feeder settings

admin

well having trouble getting the miller mig welder at work dialed in . the heat is in volts which im used to but the speed settings are different than what i was taught to use instead of inches per minute the dial has numbers that range from 1 to i think 8 . so i guess my question is what would these number be in inches per minute . i dont know the model of welder it is all i know is that both the feeder and welder are millers .
Reply:Yea, it's a rough indication of IPM. That's pretty standard on analog style Miller feeders, and even the older digital readout 50 series go up to about 800 IPM. The numbers are just a ballpark setting anyways. Get your voltage set. And put the indicator of the dial to the number which represents IPM in rough hundreds and dial in from there.I am not a professional welder, but I work on these feeders a lot. I usually set the number high, then slowly dial back until I get it where I want it. You can also use a calculation by setting the feeder, and running wire out for a timed period than multiply it to get IPM. It'll get you close.I'm sure somebody else can explain that better.Hope this helps.Expert Garage Hack....https://www.facebook.com/steven.webber.948
Reply:so its the number x 100 so 2 would = 200 imp . im used to running 16ga with a lincoln power mig on 18.8v and 175imp but when i tried putting the miller on 20v and speed of all it did was squirt the wire into a pile like crappy caulk it didnt even arc
Reply:You'll prolly have to play around with it. Knowing what kind of machine would help a little. They all weld a little different, and can operate considerably different from each other. If you're not even getting an arc, there may be other problems. If you set the welder to 20 volts and start turning down the wire speed, it should even out at some point.More info is needed. Are we talking identical wire and gas as on the Lincoln? Is the machine you're trying to use used every day, or recently powered up? Are you sure of its proper operation? Some Miller CV power sources also have remote voltage capabilities and if accidentally turned on, practically kill the power unless a proper remote is connected correctly.Just too many missing points to accurately access from here.Expert Garage Hack....https://www.facebook.com/steven.webber.948
Reply:the gas is both c25 the lincoln runs .030 i dont know on the miller ill have to get back to you on tuesday on the model of the miller and ill play with it a little to .
Reply:Yeah, check the wire size and model of machine.Knowing if it's used every day, or you just plugged it in will help too.Expert Garage Hack....https://www.facebook.com/steven.webber.948
Reply:yeah its used almost every day but its mostly on high volt like between 30-40
Reply:Check the wire size first. At those voltages, I doubt it's small wire.If you changed it out, and readjusted it you may have other problems, unless you just need to find its sweet spot.Expert Garage Hack....https://www.facebook.com/steven.webber.948
Reply:Miller is usually a percentage on the numbers on the wire feeders.  The range of about 50-750 IPM. 1 would 10%, 2 would 20% of 750. Another thing you can do is feed the wire for 15 seconds, measure and multiply by 4 to get inches per minute.
Reply:im thinking my problem is larger wire .
