Miller 211 MVP: VDC and Wire speed chart.

admin

After asking the guys on here about setting up my machine, I was told to find out the actual output for the 211 so I know what I'm doing when I get a correct set-up.  So I did. I thought I'd post up the chart I made if any other new guys like me have an interest in it. Attached Images
Reply:Always wondered, but never got around to doing that with my MM210 - just went by the settings in the door chart.I'm guessing you just hooked up a volt meter while welding?Dave J.Dave J.Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~ Syncro 350Invertec v250-sThermal Arc 161 and 300MM210DialarcTried being normal once, didn't take....I think it was a Tuesday.
Reply:Those voltage values are open circuit readings.  When you're welding, the voltage for the 1-10 dial settings will be significantly lower then the OCV that you have on your spread sheet.ESAB Migmaster 250 Hobart Ironman 230Multimatic 215TWECO Fabricator 181i & 211iHH125EZ - nice little fluxcore only unitMaxstar 150 STH - very nice
Reply:Yes, sounds like alot of voltage output for that machine.  IIRC, my 280 amp output MM200 put out 32 volts max and my XMT304 maxes out at 35volts.TA Arcmaster 300CM3XMT 304S22P12 suitcase feederX-Treme 12VSOptima pulserTA161SMaxstar 150STLHypertherm PM45OP setupStihl 020AVP, 039, 066 Magnum

Reply:Thanks Dan, I wondered how these values change when actually welding.
Reply:Miller has a voltage chart in the 211 manual, page 13.At 210 Amps you should have around 21V (230VAC).BTW, I have a Lincoln inverter mig that is a 200A unit and it delivers 24V @ 200A. That's to be expected though since it's an inverter and it has a little higher duty cycle than the Miller 211. Open circuit voltage is 57V.So voltage needs to measured under load.

Reply:Really.A 100W bulb would be an insignificant load on a welder, shouldn't lower the voltage by more than a fraction of a volt.Load banks for testing welders can be varied from a couple of ohms down to less than a tenth of an ohm. They tend to be large, heavy, and expensive.You can jury-rig a load bank from stainless rods and/or large power resistors, but some knowledge of Ohm's law would be helpful.JohnA few weldersA lot of hammersA whole lot of C-clamps

Reply:Originally Posted by joshuabardwellPS: Assuming a 100 watt bulb and 120v service...R = V^2/WR = 120^2/100R = 144 ohmsSo if a welder's load bank has up to "a couple of ohms," seems like a 100 watt bulb should be more than adequate.
Reply:Originally Posted by k45A "couple of ohms" is about two orders of magnitude (100x) from 144 ohms.    Your 100 watt light bulb is drawing 100 watts when fully lit.  A welder putting out 200 amps at 20 volts is 4000 watts.  A 100 watt load...it wouldn't even notice it.
Reply:It would be interesting to know what the door chart states is the correct WFS and voltage for, let's say, 1/4" steel with .035 wire.   Then we could look at the Miller welding calculator for MIG and get an approximation of what Miller estimates the machine puts out.TA Arcmaster 300CM3XMT 304S22P12 suitcase feederX-Treme 12VSOptima pulserTA161SMaxstar 150STLHypertherm PM45OP setupStihl 020AVP, 039, 066 Magnum
Reply:Originally Posted by joshuabardwellFor what it's worth, I didn't have the welder on max. output when I was doing the testing. It was only down around 40 amps. I didn't want to risk getting a worse shock than necessary.

Reply:Originally Posted by Drf255You're not gonna get shocked by a MIG welder.  The voltage is too low to create a strong enough gradient to run through your body.
Reply:Originally Posted by k45Doesn't the voltage vary depending on the gap?
