Setting up Miller 272

[joefisherff]

I just purchased a new Miller 252 Mig welder and am attempting to set it up but I am running into an issue with the wire feeding. I moved the spool off my old machine, fed it into the rollers, adjusted tension and it feeds so far and then stops, I've adjusted alignment, tension, feed speed, etc. but the result is the same. Wire diameter is .035, it is on the inside groove, moving tension up or down does not change things once it stops. If I pull the wire out, cut it off and retry it I get the same result it feeds so far, sometimes through the gun but not always and then stops. It is an older reel of wire could it be oxidized or something the inhibits it feeding? Thanks in advance for the help.Joe

Corrected

Sorry it is a 252, brand new, I haven't even tried to weld with it as I haven't been able to get the wire to feed completely through the gun. It is brand new.

Are you aware of this?? if your wire speed were set to ZERO... then wouldn't it stop at the end of the 3 second runin..??

6-3. Jog Mode

If the trigger on either gun is held for more than 3 seconds without striking an arc, the unit will automatically shut off weld power (and shielding gas output on MIG or push/pull gun), but will feed wire continuously at the preset wire feed speed (which may be faster or slower than Runin Speed) until trigger is released. Jog wire feed speed is the same as weld wire feed speed, so any time jog speed is changed, be sure to change back to weld wire feed speed before welding. Jog wire feed speed for the spool gun and push/pull gun is limited to 300 ipm (7.6 m/min)

try feeding the wire through by hand. The liner may be obstructed.
