Mig splatter....

-
The issue is the china made wire is a crap shoot. You have no idea what they melted down to make the wire you are running. the contaminants in the wire are causing the spatter. You may get halfway through the spool and find it runs well without any changes at all. It doesn't make a difference if you but it from a weld shop or harbor freight if the weld shop is selling the cheap Chinese wire. You can try turning the voltage up and wire speed down so you are spray arcing to see if it cuts down on your spatter.

Visited the welding shop the other day. They told me that the wire I got is indeed some generic stuff. Talked to them about the troubles, they offered to swap the wire put for what they consider a very good wire. They did tell me that the cost of it is more than double of the stuff I bought but they would discount it as much as they could.
The o-ring on the previous liner just didn't look right. New liner helped some, but still getting a crap load of splatter...
 
Finally figured this out....my machine apparently has some sort of trouble with generic liners. Got a Miller liner, 0 splatter....as long as the settings are close to right.....
 
That is good that you figured it out. I wonder it the generic had some sort of cotamination in it
 
The aerosol spray mentioned above works well. It won't stop the splatter but will keep it from sticking to your project. The paste to dip your welding tip in keeps it from sticking to your tip. Vaseline is a good substitute for the dip.

So the metal liner was the culprit? I got a dinosaur "Dual Mig-131" But its made in Italy. Feed roller tension is shot so Im using a lever and spring. I have yet to try gas, but the HF wire and even Homie Depot (Miller?) wire seems to work ok (lots of spatter) but Im no welder so OK to me might be dismal to a welder. Lots of burn through on exhaust pipe, but its usually super thin used header pipes.
 
Pishta, to help prevent burn thru, lower voltage setting just enough to get a proper meld of the material. Then use a continuous series of ( spot ) welds , approximatly 1/2 second each allowing a couple seconds between for cooling. you can achieve a decent looking weld without the burn thru that happens often when trying to run a countinious bead.
