Stick with me and you’ll find out what it is.
Why you need it and how to use it. You’ll even get some suggestions of good products for you to use.
What Is Spatter?
Spatter is the beautiful rainbow colored sparks seen during those classic welding shots.
Look close and weld spatter is composed of tiny pieces of molten metal, thrown out by the welding process.
And that weld spatter lands all over your welding area.
On the part you’re welding, your welding table, the floor, you and your clothes, up and into your welding torch head.
I have an article that goes into more detail on Spatter. If you are interested and want to know more about those little specs that are causing you all that trouble, take a look at my article ‘What is Spatter in Welding? And Why it Sucks‘
Problems Caused By MIG Welding Spatter
​MIG welding spatter, also known as bb’s, cool down and become stuck to your work and difficult to remove. The welding spatter defaces your work, blocks up your torch head and can cause a short circuit when the weld spatter stuffs up your nozzle and contact tip.
When this welding spatter prevents your wire from feeding out and or blocks your shielding gas, it can cause your weld to fail, unless the spatter is removed.
The last thing you want when you’re just starting welding is a ton of spatter all over your novice bead laying.
But then is exactly when you get the most spatter.
Because you’re not experienced enough in your MIG set up and so you’re going to produce a lot of spatter until you know enough to reduce spatter to the minimum.
What Causes Spatter When MIG Welding
- ​Typically when welding using flux core wire in a flux core welder. Flux core wire is notorious for producing more spatter.
- When using 100% Carbon Dioxide shielding gas with your MIG – 100% C02 is often used because the shielding gas is cheaper to buy. The by product of this saving in money is often a higher incidence of spatter.
- When your MIG weld settings are not quite right, to high or to low wire feed speed, to high or too low gas, or contamination on your weld piece.
You’ll find an article on the site about spatter. It covers 7 other causes of spatter. It’s worth taking a look and get some idea what might be causing your spatter.
How To Reduce Weld Spatter
​Let’s take a look at ​some areas where spatter is formed.
- ​Correct set up of your MIG for the metal you are welding will reduce weld spatter but is unlikely to get rid of it altogether.
- Read the welding parameters chart supplied with your welding wire, again to find out the correct settings for the wire you are using.
- Use the right type of shielding gas for the metal you are welding. ​
- Use low or spatter reducing flux core welding wire from ESAB or Lincoln Electric.
There’s a document that goes into 20 points that you can look to. In your fight to take the spatter your welding produces, down to the absolute minimum. Do take a look if you want to know how to fight your welding spatter.
And when you have done the best you can …
The Defense Against Welding Spatter Is Anti Spatter For Welding
​Given that you will have spatter – particularly as a beginner, the best defense is to stop the spatter from sticking to the metal surfaces around you.
Stop it sticking to your contact tip, nozzle, your work piece and your welding table. The best way to do that is to use welding anti spatter products – anti spatter for welding.
What Is Anti Spatter Spray?
Although anti spatter is called anti spatter, it doesn’t actually stop the spatter – that pretty spray of rainbow sparks from forming. Only correct set up of your MIG welder can reduce that.
What anti spatter spray is, is a product you spray. Say on your welding table and on parts of your welding project to prevent spatter sticking. Those hot pieces of metal spotting your project and your work table giving you hours of clean up.
To stop spatter sticking to you? Well that is what gloves, welding helmets and suitable coveralls are to do. A bandana around your neck and ear plugs can stop those pesky pieces of spatter from heading down places they really ought not to be.
Anti spatter spray contains active ingredients normally silicone, a solvent and is most often petroleum based. It can also be water based.
Anti spatter spray products are also available as gels or dips specifically to stop spatter from sticking to the end of your MIG nozzle and contact tip causing a short circuit.
Welding Anti Spatter Products
​Anti spatter products are available as a spray, or a dip or a gel. They don’t prevent spatter – only correct set up of your MIG welder can do that or at least minimize the production of spatter.
What they do is prevent spatter or bb’s from sticking to the surfaces where the anti-spatter is applied.
How To Use Anti Spatter Spray Or Gel Or Dip?
​All the anti spatter products have to be applied as a preventative – and that means before you start welding.
Any spatter sticking to your work piece or nozzle should then be easily brushed off.
Where To Use Welding Anti Spatter Products?
​Anti spatter for MIG welding is used on the metal objects in and around your weld area, where you don’t want the spatter to stick.
You use where you want and need your finished work to look good.
Spray and of course don’t forget that in addition you can use a physical shield to prevent spatter from reaching areas around the work shop.
Cover and protect the areas of your work piece that are not to be welded as best you can.
Spray and use on your welding table before you lay the piece to be welded. This will reduce the spatter sticking to your welding table.
Use nozzle gel for MIG welding or dip on your torch head nozzle and on your contact tip.
Spatter then should be easy to wipe off when you have done welding your work.
After applying an anti-spatter spray coating and welding, you can brush or tap off your contact and nozzle to remove the spatter.
The best way to remove spatter is to prevent it sticking to your work piece and the surrounding area by using the preventative methods I’ve suggested.
It’s far harder to remove when it is stuck fast and then you need an angle grinder to remove it.
Possible Problems With Using Welding Anti Spatter Spray
It’s not all good I’m afraid.
Welding anti spatter spray’s active ingredients are generally silicone, solvent, petroleum based or water based. Anti spatter for MIG welding can be noxious and harmful to you and to the environment so it is worth choosing the product you use carefully.
There are some problems with using certain welding anti spatter sprays.
They are;
- Difficulty getting off – they can leave a greasy residue which is difficult to completely remove without chemicals, the greasy surface makes it difficult to paint your work later
- Staining metals – some welding anti-spatter sprays can darken and stain the metal
- Contamination of the weld leading to porosity – unless the product specifically says it does not cause porosity it is safer to assume it does. Keep the welding anti spatter spray away from the actual joint
- Environmental hazards – some welding spatter sprays are not environmentally friendly. In fact some contain, Methylene Chloride, which has been shown to cause cancer in lab animals. If your concerned, use a respirator or avoid cans with this chemical in.
- Complaints of water based welding anti spatter sprays rusting parts, particularly in the more humid parts of the country
The exact same materials in the welding spatter spray that stops the spatter sticking can compromise the welded joint. Spray around the area, protect the joint you’re planning on welding. Do not spray directly onto the joint you are welding.
All that said as long as you choose carefully the weld spatter spray product you use for your particular circumstances; they are a boon to use.
Welding Anti Spatter Spray Uses
​Anti spatter spray welding is easy when you follow a few tips.
Shake the can for at least 30 seconds to a minute to fully distribute and mix the materials inside.
Use by spraying a light coat of welding spattter spray around the area where you are welding. For example;
your weld table, or
if welding a piece out in the field or car repair work, spray the metal surfaces around the joint to be repaired to prevent spatter sticking.
Spray the piece you’re welding, though avoid spray on the weld joint itself.
If you do get a coating of the anti spatter on the weld joint you risk contaminating your weld.

Anti Spatter Gel
​Is also known as welding nozzle gel or dip.
What is it?
Whereas welding anti spatter spray is generally used around the welding area. Welding nozzle gel is specifically used and is effective for preventing spatter from sticking to your torch head nozzle and contact tip.
Welding Nozzle Gel Use
​Before use, make sure any existing spatter is cleaned off your tips and nozzle using welding pliers or a wire cleaning brush or file.
Run a few inches of starter beads on a spare piece of metal to warm up the contact tip and nozzle. These gels are used on a hot nozzle and contact tip.
Dip the nozzle into the tub of gel to about an inch in.
Take the nozzle out and leave the nozzle facing down over the tub to allow the excess to drip off back into the tub.
Alternatively you can
Apply the welding nozzle gel with a small paint brush
whether dipping or brushing on;
lay another one inch bead on your spare piece of metal to use up the wire that has been in contact with the dip.
Then weld as normal
Check at the breaks in your welding for spatter
tap the nozzle on your welding table to allow the bb’s to fall out or
brush off any bb’s out of your nozzle. They should come of easily and re dip.
When you have finished your welding session give a last clean so that your nozzle and torch contact tip are ready for your next weld session.

Anti Spatter Spray Four Alternatives
What are the anti spatter spray alternatives?
Here are the alternatives to using welding anti spatter spray I’ve heard of.
- There is the tried and tested use of welding pliers to clean the bb’s off your nozzle. This is the only anti spatter spray alternative I can happily standby. Timely use of a good pair of welding pliers will clean those bb’s off your nozzle.
- Pam cooking oil used as anti spatter spray. Some swear by Pam’s original formula others prefer to use the garlic flavored version. Complaints of Pam leaving a sticky residue from other users. It’s a possible cheap anti spatter spray alternative as many swear by it. It’s not a specialist product of course. However if it works for you …
- WD-40 spray. With the added benefit that it keeps rust at bay. Definitely one to keep away from your weld joint or you will end up with a contaminated weld.
- Engine Oil. An unusual one to try though I would say the same about this as with the WD-40. Try and see if it works for you and your situation and keep away from your weld joint.
