5. Harris Products Group E70S6F9
Now we come to the final product on the list, the Harris E70S6F9, which comes with additional deoxidizers that offer better wetting and an excellent welding experience. It is a great product ideal for a wide range of welding applications, whether at home or in commercial spaces.
Product Highlights
MIG wires are meant to be used with specific gases for getting the desired results. That said, the E70S6F9 model from Harris Products Group can be used with a combination of argon and CO2 or with 100% CO2 alone. Indeed, it allows you to get great results even if you do not have argon close at hand.
Additionally, it is a general-purpose welding wire with additional deoxidizers that help provide better wetting, which helps in getting a flatter bead shape. This shape helps in ensuring that the flow is smoother and there is no resistance, which results in cleaner welds with less splatter.
This MIG wire also conforms to the AWS A5.18 ER70S-6 standards, ensuring higher quality welding even on dirty or oily metal surfaces. If you intend to work with old metal sheets that are rusted or dirty, this is the best product for the purpose.
Rest assured, the welds will come out cleaner and provide a better appearance.
What’s There To Like About It?
I like that this product comes with even more deoxidizers than wires that are ER70S-3-certified. As you may know, the greater the number of deoxidizers, the better the MIG wire performs. On that note, this product is excellent for welding purposes.
And since it can also be used with CO2 alone without needing to use argon, it has a wide variety of applications. On that note, it is one of the most versatile MIG wires you can currently purchase from the market.
What’s There Not To Like About It?
The only problem with this product is that it does not have any rust-prevention coating, so it tends to corrode quickly. It is recommended to use the product soon and then store it properly to prevent rust. However, there are no complaints regarding the performance of the product.
Pros and Cons of Harris Products Group E70S6F9
Pros
Cons
- Contains additional deoxidizers providing a better wetting, giving a flatter bead shape
- Usually used with 75/25 (argon/C02) shielding gas or with higher contents of argon
- Can also be used with 100% C02
Buyers Guide
Now that I have told you about the best MIG wire for rusty metal, let us consider some of the factors you need to think about before purchasing. These will help you find the product that is best suited for your requirements.
1. Type Of Metal
The first factor that you need to consider when buying a MIG wire is identifying the type of metal surface that needs to be welded. The three most common metals used for the purpose are carbon steel, stainless steel, and aluminum.
These are called base metals and determine the thickness and composition of the welding wire that should be used.
2. Required Level of Cleanliness
Generally, solid MIG wires used with shielding gases produce a cleaner weld with a lesser amount of splatter than flux-cored wire. While splatter does not affect the weld quality, it requires additional effort for grinding, polishing, and finishing to remove it before painting.
3. Type Of Wire
For best results, the welding wire should be made of the same material as the metal required to be welded. For instance, it is recommended to use stainless steel wires for welding on stainless steel surfaces.
On that note, consider the primary metal of the surface when buying a welding wire. Proper quality control checks and inspection with laser micrometers can ensure that the results are consistent.
4. Wire Thickness
The thickness of the base metal determines the thickness of the wire to be used. Generally, the thickness of the wire is mentioned on the product packaging.
Here, you must remember that thicker wires work better for thicker workpieces, but a range of thicknesses are compatible with standard wire diameters. That said, the standard wire used for most welds has a diameter of 0.35 inches.
Undersized wires can often cause erosion of the tip ID due to arcing, while oversized wires can cause problems like tip blocks, more significant feeding force, and wire slippage.
5. Composition Of The Wire
There are two standard methods of analyzing the chemical composition of MIG wire — one of which works by controlling the chemical composition of the wire. In this method, every cell of the raw material is analyzed twice to ensure the correct chemical composition. That said, selecting the wire with the right composition is also one of the critical factors that should be considered.
It is common to find MIG wires containing additional elements and the core metal. These elements, which include silicon, manganese, and titanium, can help make the wires stronger, more stable, less porous, or prone to oxidation. Such wires can offer additional advantages for welding processes.
6. Packaging
Different manufacturers offer various packaging options, ranging from the open spool wire system to packaged wire drums. Open spools are easier to work with, but the wire tends to damage much more quickly. On the other hand, wire drums are more durable but require more effort while using them.
Frequently Asked Questions
I have listed down the most commonly asked questions regarding MIG wires in this section. I have tried to answer these questions to the best of my ability to help you clear your doubts. So, read on to learn more.
Different MIG wires are available in the market, offering varying thicknesses and compositions since not all MIG wires perform the same on all metals. Therefore, it can be said that the type of MIG wire does affect the quality of the weld, and it is recommended to select the wire that is best for a particular scenario for getting desired results.
Due to the different parameters and characteristics of different types of wires, you should always check the datasheet or specifications of the wire. These sheets are generally included with the wire or are available on the manufacturer’s website. Such sheets have essential information such as the proper usage and storage methods, following which you can get excellent results from the wire.
Both ER70S-3 and ER70S-6 are the two major types of wires that you can purchase from the market. The classification is made as per the American Welding Society (AWS), which ensures that they have a tensile strength of 70,000 psi.
ER70S-3- certified options are most suitable for welding steel that is rust-free and oil-free, while ER70S-6 wires are ideal for joining steel that is slightly layered and may have rust.
MIG welding wires can last for a long time if stored in the original packaging at room temperature and away from moisture. However, if the wire gets exposed to other elements or excessive moisture, it can start to rust and even pick up dust and debris from the air. That said, these factors can compromise the integrity of the MIG wire.
The only difference between MIG welding and MAG welding is the type of shielding gas employed. A MIG welding process uses inert gases or gas mixtures like Argon or Helium, or a combination of the two since they do not react with the metal.
On the other hand, a MAG welding process uses active shielding gases that can react with the filler metal and affect the resulting mechanical properties.
My Final Recommendation
With that, I have reached the end of my list of recommendations and complete guide. I hope the list can help you easily find the product that is best suited for your needs.
Before I go, I would like to tell you about my personal favorites; the INE USA 8.0245E+12 model is an excellent choice if you are looking for a high-performance product. And for a more economical option, the Hy-Weld Spool Mild Steel MIG Welding Wire makes more sense. Finally, the Hobart H305406-R22 model is the best MIG wire for rusty metal suitable for various applications.
On that note, I will be signing off. Until next time!
