Wire Feed Speed to Inches Per MInute.

admin

Is there an acutual formula to convert WFS to IPM, or do you have to just use the old tape measure trick? (hold trigger for 6 seconds, measure, multiply by ten)I can formulate the amps to IPM, but the machines at the tech center read WFS.Just curious.

Reply:Tape measure.Or look up the speed tables in the owners manual,if they have them.
Reply:Tape measure,  I do 15 secondsx4 a bit more accurate.   on machines that are done from 0-100% you may find that the rate of increase from say 1 to 2 then 2 to 3 etc. is not linear.. some steps will change wire speed more than others...Tiger Sales:  AHP Distributor    www.tigersalesco.comAHP200x; AHP 160ST; MM350P,  Spoolmatic 30A; Everlast PowerTig 185; Thermal Dynamics 60i plasma.  For Sale:  Cobra Mig 250 w/ Push-pull gun.  Lincoln Wirematic 250

Reply:Some machines are marked 1-10. 1 being a minimum speed and 10 being maxed out. Wire feed rate may vary depending on the power setting on the machine, or it might be constant. They only way to know for sure is to measure it as mentioned above. The tech school just got new digital feeders on some of the XMT's. I find them a PITA right now, as the feeds don't exactly corespond to the older ones with the 1-10 dials. I have to spend a bit more time dialing in the machines to get my settings right. I just have to relearn what the settings are for the digital feeders. ( the fact the older ones are beat to $hit probably doesn't help much).Unless you are working to a specific WPS though, it really doesn't matter for most. Just set the machine to what gives you the weld characteristics you want. Whether the dial says 348 IPM or 4.5 won't matter. In fact on another similar machine you might find those settings won't give you the same results. They are just a reference to use to get started or reset to a known setting at a later date. Those that do this enough, can usually tell how close you are to the right settings by what the machine is, and what the readings are simply from experience..No government ever voluntarily reduces itself in size.

Reply:I am guessing that on that machine it just reads 0-10 or 1-10 on the dial, and the guy was just saying where the WFS knob is on that particular machine.  In this case, the number is arbitrary and meaningless.  If you want an IPM number for the WFS at the stated setting, you would have to run the wire out for a certain length of time, measure the length and do a bit of arithmetic.  Obviously you would have to have the machine in order to do so.If you are interested in spray transfer... here are a couple of links that may be of interest.http://www.esabna.com/EUWeb/MIG_handbook/592mig1_6.htmhttp://www.weldreality.com/magna%20s...s%20pulsed.htm"Great spirits have always encountered violent oppostion from mediocre minds."  --  Albert Einstein

Reply:I think ill sitck to my tape meausre lol.
Reply:Tape measure good.   IF your machine goes to 400 ipm, then setting it on 5 should be 200 ipm.  SO knowing the max wire feed in inches per minute is still a good guide for YOUR machine.DavidReal world weldin.  When I grow up I want to be a tig weldor.
