Im getting a lot of spatter Mig welding. Im using C25 gas and .030 wire and im welding 3/16 steel and I have my settings at 21.5V and 550 ipm. Im plugged in to 230V and Ive tried lowering the wire feed speed but it still spatters a lot. What can be causing all this spatter?
Reply:You are likely in an amperage/voltage range where 030 wire can no longer run in short circuit mode. If you can see the tip of the wire start to ball, then you are in globular transfer which is inherently more un-stable. You can either decrease the WFS and Volts to stay away from this transfer mode, or you can try to up the volts to get into a quasi-spray transfer mode. It's not a true axial spray transfer because you do not have enough Argon within the shielding gas mixture to minimize the droplet diameter and straighten out the trajectory, and you might get excessive undercut, but the spatter should reduce somewhat. Or just switch to 035/040/045 wire that can still run in short circuit at elevated amperage/voltage levels.

Reply:Ok and the MIG welder I have is a cheap Eastwood 180 welder. So I dont know if that has anything to do with it. Also could drive roll tension cause this spatter?
Reply:What do you call a lot of spatter?Dave

Reply:While Im welding you can see a bunch of sparks and spatter. And Ive tried bumping the voltage up and the wire speed down

Reply:Like Oscar said. Just grab a piece of scrap and dial in your settings till you tweak it how you like it. And then burn up a few rolls.Lincoln 330MPXLincoln Power Mig 256Lincoln LN-25X Wire FeederMagnum PRO 250LX GT Spool GunModified Lincoln 225¼ Ton of Torches OFC-A OFG-AAir Carbon Arc GougingEverlast 62i Plasma CutterIngersoll Rand Type 30 14hpInstagram: #Freebird Welds
Reply:I agree with Freebirdwelds and OscarI would use factory settings Then move the voltage up and down. It would help with photos too.Dave

Reply:Probably coming out of the puddle too much or running too fast. Find a lot of berrys coming out of the puddle when pushing the puddle. We run couple more volts thenYou and run about 370 wire speed. So you might have to much wire speed. Berrys are a key thing to look for when making a weld. Usually let’s me know I’m moving too fast when I see and hear berrys. And make sure you’re tip is smooth and I bad cup can mess with you tooLast edited by motolife313; 04-05-2022 at 09:49 PM.
Reply:The first thing I would check is that the polarity is correct and not set for gasless flux core. You need electrode positive for MIG and electrode negative for gasless flux core. Second, your settings are WAY high for the application. You shouldn't need more than 20 volts (if that) and 400 inches per minute (or so) for 0.030 wire and 3/16ths mild steel in the flat position. Even less if you are going vertical up. I might go up to 21-ish volts if I was running 100% CO2 gas, but you said C-25.Miller Multimatic 255
Reply:It is interesting 🤔 the difference ways to fix this problem. I have used both mix and co2 and go to machine and fix it in under .Now try fix problem over the internet 🙄 something that can do from instinct. I could even be stickout too.Dave

Reply:Sometime it helps if you stand on one leg while welding.

But as others have mentioned Stick Out ( Electrode Ext) and Contact to Work Distance also have an effect on spatter.You can check the tension against a piece of wood.
