I keep trying to find a way to increase the wire speed on my 140 mig welder. Understanding the power to the motor is a pulse signal, and the motor I have is 24v, if I change to 12v motor, would this increase my wire speed. I also understand there is a lot going on "under the hood", and if I change the motor would this also draw too much power and burn out the wire speed circuitry??? Last if get a 24v motor with a different gear ratio (compete new unit), would that also draw too much current and damage the wire speed circuitry????Thanks in advance,PeteEverlast i210 with 200a spool gunEverlast i140eLOTOS LTP5000D Non-Touch Pilot Arc "Things are never so bad that they can't get worse...."
Reply:Why are you trying to increase the wire speed?.No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear. Actually, a government bureau is the nearest thing to eternal life we'll ever see on this earth! Ronald Reagan

Reply:Even with helium there is no way a 120 volt machine will spray 3/64" wire. Another issue when you get in higher wire speed is erratic arcing , since the wire is shooting out so fast
Reply:It might be easier to figure out how to put in a larger drive roll.Larger diameter equals more ipm for the same rpm.

Reply:FWIW and I would be into a bigger machine......but that's just me.
Reply:Simply purchase their optional spoolgun. The welder instruction manual states you will need their spool gun when welding 3/32 or thicker alum. They also explain the gun allows for much higher wire speeds required to maintain spray in alum...The gun triggers off the welder, but contains it's own drive motor and drive wheels.I have two spool guns for my migs and don't regret buying them.

Reply:I thought to spray arc you need to be above 25volts. The Everlast i 140 rated output is max 140A/21V @ 25% Duty Cycle/40º C(this is off evrlast's website). Which tells me that you are not spray arc welding still in short circuit mode.Klutch 220si mig , stick, and dc tigHobart 140 AHP ALPHA 200X 2016Lotos LTP5000DSmith O/P
Reply:You're thinking of spray arc on steel.
Reply:Originally Posted by fpsAccording to Everlast, the signal for the spool gun comes from the welder, which drives the spool gun at the same speed as the welders' standard wire feeder (300ipm).I realize I should move up to bigger welder, but I can't see doing that just because I want to spray .025 wire.

Reply:Originally Posted by wornoutoldwelderI know with my Hobart guns they will squirt wire lots faster than the built in wire drive.

Reply:Originally Posted by M J D20 volts , minimum should get you into spray with 4043, .035 wire. I really doubt that this or any other 110 volt mig can really achieve this.

Reply:Originally Posted by M J DYes, spray will be much smoother. On the bead profile the ripples will be much less pronounced. Reason being, the higher heat and travel speed doesn't allow it to " freeze" as fast. The "freezing" is what causes the ripples.I never said anything other than that the picture of the weld you showed was not spray transfer. I have never studied the scientifics of how every aspect of how every process technically works. With that being said, I have used hundreds of pounds of aluminum wire, the majority being .035 4043. Lately I have been using 4943 for the most part, but that's pretty irrelevant since I use almost an identical setting as 4043. What this all means it takes a lot of heat to spray aluminum, and that's where you are lacking. As for the aluminum fab on bodies, a lot of it is done with pulsed mig, which is an all together different thing.
Reply:The 140E is an inverter MIG. It will put out higher voltage than a transformer. The wire speed should top out at about 360 ipm.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT

Reply:You should try .030 before going to .025. I can't see .025 feeding well . |
