mm251 stutters and pops
Could a mig gun cause a MM251 to weld, sputter and pop, weld, sputter and pop again? When it welds it welds good for a few inches. IT's stutters on starts too. The machine is like brand new, it's only had one 33 lb roll of solid wire through it. it's getting worse, I could deal with it before today, but today was the last draw.... it's almost 44 mag time.Tags: None

I just can't use factory recommendations as they are never even ball park. What kind of steel projects are you blasting with that black beauty abrasive.

This technology provides a smooth, spatter-free start. No pop-gun starts or spatter to clean up. It gives a temporary burst of energy on start up to help initiate the arc.

Please clarify one thing for me. What exactly is hot start and its function.

Tex, the #8 or # 79 wire removes the hot start from the machine... It seems to me the machine is welding much better in all respects period.
I run Black beauty through the blaster. I use a 1/8 pipe for the nozzle instead of the ceramic 3/32? nozzle Texas Blasters sent me with their hose. It was to small of a hole. The black beauty would plug the hose at the tip with the valve just barely cracked. In order for the media to come out so little of it could be sent through the hose it was hopeless to get anything done.Last edited by tackit; 08-12-2013, 12:06 PM.

What is the purpose of the #8 or #79 wire? Is it something to remove only if it stutters and pops or something that can change characteristics of a good running 251.

I like that blaster. What kind of abrasive you using for the stated applications.

Fixed stuttering and popping
If you have a 251 that stutters and pops on starts you can remove the # 8 or #79 wire (depending on your machine) from the contactor block and your problems will go away... at least mine did. My 2003 MM251 has never welded so nicely since I pulled the # 8 wire off the contactor. Thanks Miller for the TipThe #8 wire is the wire with the yellow marker on it.

I would at least ck all ground connection nuts and grind area bare to connect ground cable.
Just a thought. Greg

Happy to help a Texan.
