How To Reduce Excessive Mig Welding Spatter

Stick Welding Benefits

When you ask some welders,what the problem use mig welding machine,the same answer must be mig welding cause spatter…MIG setups use electrode wire that bonds with the metal to form the weld, and spatter is the excess molten wire that bonds with everything else.

The first Question What is Spatter? Have you ever seen those tiny metal balls melted around a piece of welded metal? That’s spatter. As the name suggests, it is when molten metal is spat all over.

How To Reduce Excessive Mig Welding Spatter


Too much spatter can lead to downtime for cleanup and wasted materials. And, if it bonds with your workpiece it can be hard to clean when the spatter cools and solidifies. Not only do they leave a mess that you then have to take time to clean up but they can burn when it hits your skin. besides, it can clog your torch head and cause it to short-circuit.

5 Tips To Reduce Excessivr Mig Welding Spatter

In fact , there’s no “how to avoid welding spatter.” if you’re having trouble with excessive spatter when MIG welding and it is ruining your work, Here are some tips.

1. Correct Parameters
inspect your machine parameters to make sure they’re running at the right settings for your application.

The correct amperage will be determined by the speed of your wire. If your amperage is too high, it will cause spatter. Oppositely, a voltage that’s too low will also lead to the same result. Your gun’s manual should give you a suggestion on the correct voltage.

Be sure it’s correct. If you’ve recently switched from solid wire to flux-core, this one is easy to overlook.

2.High-Quality Or Correct Consumables 

Quality consumables aren’t necessarily the most expensive, but they’re reputable, long-lasting, consistent, and most importantly the right quality for your specific application. Low-quality wire can vary in diameter as it feeds through the gun at different wire speeds, a less-than-optimal contact tip or liner can clog more quickly.

3. Keep Clean

Dirty surfaces anywhere from the workpiece to the gun liner can lead to excess spatter. Check your wire and liner for rust or dirt, and your workpiece for mill-scale, oil, rust, paint, grease, or other contaminants.

4. Proper Use

Is dragging or pushing the proper technique for MIG welding? It’s a hot debate, and mostly a personal preference. But whichever way works best for you, proper technique is essential to keeping spatter at a minimum.

Optimally, you should hold the MIG gun at no more than 15 degrees from vertical. A deviation away from this can cause the shielding gas to cover the weld unevenly.

Additionally, a wide gun angle can lead to an imbalance in the shielding gas causing it all to go to one side leaving the other side exposed.

5. Stable Arc

Incorrect wire stick-out isn’t the only cause of erratic arc. It can also stem from incorrect drive-roll tension, bad ground, a dirty liner, the wrong-sized contact tip… the list is long. If your arc starts to sputter or crackle, you’ll want to troubleshoot right away to avoid spatter buildup.
