First welds with my LN-25

admin

Well I finally got off my *** to play with my LN-25.  I ran some Hobart 21b 1/16" innershield through it.I was running max voltage on my welder which is anywhere from 22-27v I believe.  Wirespeed was about 90imp.  I could have adjusted settings a bit more but I had to do this out in a dirt lot since I live in an apartment and couldn't do it there.  I didn't want to spent too long messing with it.  Once it sounded and welded good I walked away.  Welds don't look too bad, but I am spoiled by dual-shield so it is messier than I am used to.Can you spot the dime?
Reply:Not bad, thats what I was running this morning, try turning your volts down. 21b likes low to mid range of it's recomended voltage.Disclaimer; "I am just an a$$hole welder, don't take it personally ."

Reply:I think your welder only goes up to 20 volts CV.  Check the manual.Nice weldDavidReal world weldin.  When I grow up I want to be a tig weldor.

Reply:Innershield wires have a sweet spot with there parameter settings when you have them tuned in you will know it will weld beautiful.It helps if you have a second person tune it in while your welding if possible.Also sounds if that machine is close to its limit for running wire that size, what machine are you running it off of?
Reply:"The CV Tap is rated at 200amps, 20v DC. At 200amps, 13 to 20 volts are available. At 100amps, the voltage range is 17-24, and at 80 amps the voltage range is 19 to 25 volts."

Reply:Still close to maxing it out i know the miller bobcat 225 struggle running wire feeders.Nevertheless good luck you will enjoy the fast deposition rates the feeder brings to the job at hand.

Reply:Originally Posted by SandyThere are some basic rules of electricity that say 'when the current goes up the voltage goes down, when the current goes down the voltage goes up. So within a range as you change ipm for more current the voltage will be lesser. As you change the ipm for less current the voltage will increase somewhat. This will also occur to a small degree as you vary the stickout while welding. Subtle changes in stickout will cause subtle changes in current which will cause subtle changes in voltage.
Reply:Constant Voltage (wire feed) means the voltage is set by the weldor at the control panel.  Wire speed correctly set, will simply match with the voltage set, the current drawn by the machine will vary widely depending on stickout mainly. Watch an inverter machine while somebody runs a bead and the amperage will be all over the place, depending on how steady your hand is!!City of L.A.

Reply:Alan N, I was under that impression as well.
Reply:I'm a little confused at this point. I was under the impression that a constant voltage supply maintained the arc voltage at a set level. That voltage tries to maintain a constant arc length. As wire speed is increased the amperage increases to burn the wire off faster and hold that constant arc length. The only time voltage changes apprecaibly is if the operator stuffs the gun in closer or pulls it back. At that time the voltage will drop(if the gun is pushed closer) and amperage increase until the arc length is returned to the "ideal".

Reply:I used a LN-25Pro, the wire speed is lower (only goes up to 400ips, the LN-25 will go up to 700ips), but whatever you set it at is what is going to go to the gun, even if the wire is folded in half.  It has a lot more torque.  I liked it better, but they only had one of them where I was at.PatrickLincoln 175HD

Reply:david,No need to check. I can tell you that you don't. Because if you go back and look at the original post he said IPS, not IPM. I was being dopey and saying that 400IPS would be pretty fast. Then you chimed in with 550 and I was just being more dopey. I think you probably do use 550IPM. On the other hand.....maybe I am completely wrong and I weld at an incredibly slow speed!   Lincoln Power Mig 210MP MIGLincoln Power Mig 350MP - MIG and Push-PullLincoln TIG 300-300Lincoln Hobby-Weld 110v  Thanks JLAMESCK TIG TORCH, gas diffuser, pyrex cupThermal Dynamics Cutmaster 101My brain

Reply:I just looked at the LN-25 Pro.  It goes to 700 IPM while the "High Torque" one only goes to 400.I did some spray yesterday.  .030 wire, 700 IPM, 35.5 volts @ 200 amps.Worked really nice.  the metal totally atomized between the end of the wire and the piece.  I was using AG8.Amps seem low, but if you figure it out, its 7100 Watts.  In Globular transfer that would be 322 amps @ 22 volts.DavidReal world weldin.  When I grow up I want to be a tig weldor.
