Lincoln Power Mig 300 Stall Factor

[rbengines]

Anyone familier with the setting for the stall factor on the Lincoln Power mig 300?

stall factor? new one to me.... i'll call the lincoln rep today tho... are ya havin troubles figuring out the settings or.....?

found at Lincoln and coped and paste it for you

The wire should feed smoothly and
forcefully from the gun. There is only
one other adjustment possible — the
Stall Factor. This is pre-adjusted at the
factory and you should never have to
touch it. However, if you encounter
numerous bird nests, the Stall Factor is
probably too high. If you can see the
drive rolls in the power supply
momentarily stop while feeding wire, it
is too low. Calibration of the Stall Factor

is covered in the IM on page E-10.

Thanks I do know how to adjust. I just was wondering if anyone using the push pull guns could advise me on what number to put in there. Thanks

stall factor = run in for miller machines...... i can explain it for ya... when you first pull the trigger and when the machine first strikes an arc. there is a little time in between that. on miller (still dont know exactly for lincoln, but i figure, it should be the same) the run in setting is a percentage of wire speed from the settings. for example, i have the wire speed set at max and the run in at 30. 30% from the max setting is what the machine discharges the wire at until it senses the arc strike, then ramps the wire speed up to the settings....

now, i will tell you what this accomplishes. when welding aluminum mig, you can get some serious burnback into the tip and also some even more serious backlash on the spool.... as the machine starts the wire feeding process, it only lets out a slow amount of wire until it senses a good arc strike, then brings the wire speed up. if the machine were to let out full speed and it had a faulty stike, you would first burnback into the contact tip, then it would backlash the spool form the sudden stop of the wire in the gun, but the spool is still rolling on...

hope this helped

on my millers with the push pull set up, i put it at about 30% from 0... or about 1/3 of the way up... its the way i was taught and havent really experimentd with it too much... just sayin

So do I understand this? Is the stall factor a measure of how much pressure it takes to stall the feed rollers from advancing the wire?

[rbengines]

To my understanding that's correct. The amount of pressure to stall the rollers. That's my problem it doesn't stall if there's a blimp at the gun. It just wades it up in front of the conduit.

[SICFabrications]

ok.... i was wrong then.... how tight do ya have the brakes set on the roll? you should loosen the drive roll pressure to just enough to get it moving. when spooling a new roll through the push pull, i tighten the drives enough to get the wire into the gun, then back it way off. with a push pull set up, the drives inside the machine "slave" to the drives inside the gun. youre gonna make me actually look that machine up, so that i might be able to help ya out with settings now (if ya havent figured it out, i dont really care that much for lincoln and therefore dont have the best first hand knowledge of them)

flippin, i hate research! lmao!!!

The roller is at the lightest setting. The friction on the spool is light also. If the temp ever gets above 30 down here I guess I'll trail and error it till I get it right. I was just trying to get a starting point or somewhere close. Man I hate it when the machine's smarter than me.
