Converting WeldPak settings to actual numbers

admin

I was looking at Miller's site at the FC calculator in their Resources section and it got me thinking about the settings on my WeldPak.How do I convert these to actual numbers? Attached ImagesLincoln AC225 and CartLincoln WeldPak HD and CartOne hand
Reply:In the manual there may be a Chart with the Volts for what position the Voltage Switches are in.There may be a Wire speed # in there too.The WS dial is usually a percentage of the maximum speed.Figuring out the actual amps is little mo' tricky.Ed Conleyhttp://www.screamingbroccoli.com/MM252MM211 (Sold)Passport Plus & Spool gunLincoln SP135 Plus- (Gone to a good home)Klutch 120v Plasma cutterSO 2020 benderBeer in the fridge

Reply:Aw heck - reading!  I was hoping you'd just say hook up the mulitmeter to the machine and press the go button   Is there actually a particular way to do that, to test each setting combination?I really do appreciate the threads there.  I'll have a read through.  Looks like that second link will have some info I can work from.  I recall reading that first thread there on the forum but then I got        I'm terrible at digesting stuff on paper but I can pin it down when I actually see and do.  I'm one of those visual learners.Lincoln AC225 and CartLincoln WeldPak HD and CartOne hand
Reply:Monica,Just use the settings in the manual or on the door chart from the Lincoln.  That will work out (usually) pretty well.If you for some reason really-really want to 'know' what amps or volts or WFS you actually have going on, you'll have to somehow measure things.WFS is the easiest to measure.  Take machine, set as desired, then pull the gun trigger to start feeding wire (no weld needs to be done here, just feed wire into the air.  Watch out though because the wire is small and pointy and also electrically 'hot' as referenced to the machine's work clamp.)  Time for 5-10-12 or so seconds, and then stop feeding wire (let go of the trigger    ).  Wait a few seconds for the wire to no longer be electrically 'hot', and then measure how many inches of wire fed out.  Do the math to get inches/minute of wire that was fed.To get the volts or amps used, you'll have to rig up a voltmeter and/or an ammeter and weld and have someone else read the numbers (or else have a recording meter to record what happened, or rig up a video camera to record the meters as you are welding).No diss on the Miller calculator (hey, I've used it before to check rough numbers as well), but it is just ballpark numbers.  Solid mild-steel wire numbers are usually more consistent across-the-board, while FCAW numbers depend a bit more on -exactly- what FCAW wire you are using.  Which for that 'little' Lincoln should be Lincoln's NR211-MP wire anyway (one of the FCAW wires which has a relatively low required voltage to run).If you really want to get into it, you can try asking the Lincoln techs for the Volt-vs-Amp curves for that machine.  Go to the 'Contact Us' section of www.lincolnelectric.com and call or email them.  Most likely the first-line tech won't have that info and they will have to go back to Engineering to have them dig it up.But it's not really needed.  Because the settings on that machine say (yes, I went and looked up the manual from the website) to use WFS #9 for everything and to use only 2# spools of Lincoln 0.035 NR211-MP wire.18 ga steel = Low #1 voltage setting16 ga steel = Low #214 ga steel = High #112 ga steel = High #21/8 inch steel (11 ga ) = High #2Hmmm, the manual says the machine is rated 35-88 amps and 0-300 ipm WFS under load (but 0-450 ipm no-load) and a max OCV of 29 volts.  The rated output is 17 volts at 70 amps at a 20% duty-cycle.Right from the Lincoln Innershield Electrodes Welding Guide  http://content.lincolnelectric.com/p...ure/c32400.pdfPage 42.035" NR-211-MP (DC-) E71T-11  5/8" (16mm) CTWD.250 lbs/1000"50 ipm (1.3)   14V   30 amps   0.65 lbs/hr (0.3 kg/hr)70 ipm (1.8)    (1.8)   60 amps  1.00 lb/hr  (0.5)90 ipm (2.3)    (2.3)   90 amps  1.35 lb/hr  (0.6)110 ipm (2.8)   (2.8)  120 amps  1.70 lb/hr  (0.8)Yes, there is a typo in the current PDF for the voltages there.  It should be (according to some older versions of Lincoln's documents I have saved the PDFs for):50 ipm - 14V - 30 amps70 ipm - 15V - 60 amps90 ipm - 16V - 90 amps110 ipm - 16.5V - 120 ampsPrevious documents also listed the recommended CTWD for 0.035 NR211-MP as 3/8 inch, as does the Manual for the Weld-Pak HD.  The best laid schemes ...

Reply:Measuring the voltage is easy, connect a DC voltmeter across the (+) and (-) of the welder.You can measure the current with a clamp on meter, or you can install a current shunt in series, in either the (+) or (-) side of the weld circuit.
Reply:Thanks yall.  I'm interested in the actual output on my machine. I guess it's the difference in just mindlessly driving my truck vs knowing the gear ratio, tire size, gallons in the tank...specs, you know."I wanna see what this does"   Lincoln AC225 and CartLincoln WeldPak HD and CartOne hand
Reply:When I am testing a new procedure is do it the old school way.I get the machine all dialed in then I pull the trigger for 15 seconds and measure how much wire is passed the end of the contact tip. multiply by 4 and I get inches per minute IPM. Put a amp meter in line and I get the actual amps (I do an average over a minute) Volts are checked across the two leads an average is taken the same way.Same type process used for all welding.

Reply:Originally Posted by Scott YoungI can relate to this.  It took me forever finding the gear ratio for each gear of my transmission.  I also wanted to know how the tire diameter affected the ring and pinion ratio and the transmission output ratio, etc.I eventually made a spreadsheet for some it.good luck on your quest.
Reply:Originally Posted by Broccoli1Yeah but when you drive a Yugo, do you really need to know the gear ratio & tire size
Reply:Far as the Lincoln goes............they all run cold nowdays  Don't necessarily believe the crap they print on the inside of the door.  Or the numbers on the dial either  Turn it up until it works good for you.I'm running 1/8 7018AC at 135amps in order to get a decent hot puddle  Ran some 5/32 yesterday, and I had to turn the stupid machine up to 200amps before it wetted in wellStoooopid machine maxes out at 125amps DC, and it's a bit too cold for 1/8 rod at times, depending on the thickness of the materialMy old 60's vintage crackerbox ran a lot better "Any day above ground is a good day"http://www.farmersamm.com/

Reply:Yeah, I never really put too much on manf specs.  They made for good marketing and brochure filler, but real world is always a little different performance.My Cummins is rated at 325HP & 610ft/lbs...environmental factors and real world use skew that perty good.Sorry to hear about the morning surprise your pup left.  Something he ate I suspect.Last time my dog left goodies for us we spent $2k at the emergency vet to open up his stomach and get the chicken out.

Reply:Originally Posted by farmersammEes seemple..............bigger tires it goes faster with less pulling power.  Leetle tires it goes slower but will pull a house

Reply:Originally Posted by Scott YoungYep!  when you replace the ring and pinion and want to larger tires and want to have a gear you can pull with, along with the size of tire you want to use and not have your gas consumption skyrocket then you study and then compromise.running 265-75-16 with a 3.73 r&p from a 235-75-16 with a 3.08.  I can tell you the latter doesn't pull very well.  the former does and my gas mileage has improved even.  well I has improved running empty.  It sucks the fuel when I am pulling something.
Reply:nope.  but as I researched, I found it was a popular "upgrade".
