Wire not feeding right

[Oldgrandad]

My son is looking for a new MIG welder. Miller, Lincoln, and Hobart all say 6 to 8 weeks. He's opting for the ESAB Rebel 285 they claim a week. we will see. Ordered it this morning.

I'm guessing that you have set the liner nice and close to the rollers. I had a bird nesting problem a few years back and it turned out to be to big a gap after the rollers.

new tip... The only restriction I feel when feeding the wire by hand is when the wire gets to the neck on the handle kinda hard to push it passed the neck. Once the wire gets passed the neck if moves easy. I haven't tried welding with the gun for a bit using another machine I'm so fed up with the darn...

Thanks G-Man I'll check roller alignment. I've done the tension spring thing from not enough to too much and back to where I think it should be. Andy thanks the spool is wound good, the tension spring on the spool is the last thing I took apart it is spinning smooth. Next I'll put another new liner...

The motor doesn't stop. The wire isn't coming out of the gun consistently. It acts like it's there is a kink in the liner but the liner is new.

I have a Millermatic 250 serial #KC253855. Started having feed problems. Welding along and the wire stops feeding. The rollers are doing their thing but the wire just wont feed consistently.

Nice job, thank you for sharing one of the tricks of the trade that the newbies need to here about. That's what this web site is here for.

Both nice repairs. Slick, just plop a second skin on it and weld all around. Much easier and faster than cutting the pitted bottom off first.

PROPER PROTOCALS, can't say it enough. Tank was bone dry when I got it. I did not rinse or anything. Bone dry does not mean no boom. Gas gets into the pores of the metal and just won't go away. With a proper purge you can have liquid fuel in the tank and it won't explode (DON"T TRY IT) no O2 no...

The tank is from a 60's era Chrysler. Didn't think to take a picture with that wonderful, weld friendly (NOT), JB Weld repair that the guy did to get a few more miles of driving before pulling the tank. This is about my 15th gas tank repair

Step One: PURGE the tank. I use Nitrogen for...
