You are looking at 2 brand new 11 lb rolls of Mild steel welding wire. This wire is used with 75% argon/25% CO2, or 100% CO2 shielding gas. This an 8" diameter spool which has the standard 2" spindle hole. Note, this is precision layer wound wire, not random wound!! Precision layer wound is like a spool of thread, each revolution is next to the other, which feeds better and provides a more consistant wire feed rate.
This is an exceptional value, and works in any mig welder that has a 2" diameter spindle, such as the Lincoln SP135, MillerMatic 135, Hobart Handler 135 and just about every other small welder out there. .030" diameter wire is excellent for 18 ga steel, and depending on your welder will allow you to go up to 5/16" to 3/8" material, depending on your application.
Inwelds Wire is second to none!! Very High quality!
