Which welding wire to use
Despite the shielding additives, flux-cored wire is skinny enough to shoot out of a MIG gun. And the slag that comes with those ingredients is a fraction of what appears in the SMAW process. Regular flux-cored wire is often referred to as Self-Shielded or Innershield , which is a brand name sold by Lincoln Electric. Instead of ER, an E for electrode begins the number in the case of all flux-cored wire.
The number 7 in the classification refers to tensile strength, multiplied by 10, instead of 1, in the case of a non-cored MIG wire. A zero means the wire is only good for horizontal or flat welding. The digit 1 indicates the wire can be used in all positions.
The 8 signifies low hydrogen, which calls to mind the common stick electrode E NR is popular because its chemical composition meets seismic requirements for earthquake zones like California. The number. Notice the polarity is DCEN. When compressed gas is involved in FCAW, the welding process is known as either Gas-Shielded or Dual-Shielded Flux-Cored Welding , since both the flux ingredients and compressed gas produce the shield.
This code is taken from AWS standard A5. Related : Best Flux Cored Wire. As you can see, the many variables involved in choosing the right wire will take a while to learn.
That said, as an entry-level welder, however, you may find yourself having to stock consumables or replace empty spools on MIG machines for seasoned veterans. So exercising due diligence correctly selecting and storing wire products is essential to preventing costly mistakes when a welding operation begins. Depending on the application, both kinds of MIG welding wire solid and flux-core can be made from a variety of materials including aluminum, stainless steel, copper, and silver, to name just a few.
Wondering what you should think about when you choose MIG welding wire? Neither type is superior compared to the other — rather, the right choice depends on your situation and preferences. Here are a few things to keep in mind when you pick MIG welding wire. No matter what type of MIG welding wire you buy, you should always make sure to invest in high-quality wire.
Compared to lower-quality welding wire, quality MIG wire is more forgiving, can produce a more sound weld even in less-than-perfect conditions, and still represents only a fraction of the overall cost of welding.

Flux-Core vs. Desired weld cleanliness — As a rule, solid MIG welding wires used with shielding gases produce a cleaner weld with much less spatter compared to flux-cored wire.
Choosing which type of welding wire you need is easy when you know the basics and your requirements.
