MIG Welding Wire

MIG WELDING WIRE

Here you will find a range of MIG wire to suit most projects.  The correct MIG welding wire should be used for the material being welded.  Wires are divided into material type for ease of navigation.

The most popular MIG wire is ER70S-6 or SG2.  Often, when someone just asks for MIG wire, this is what they require.  SG2 is generally a mild steel wire covered in copper to prevent rusting and assist with wire feeding through the MIG torch liner.  SG2 MIG wire is a solid wire and is used with shielding gas to prevent porosity from occurring within the weld.

Gasless MIG wire is also a popular choice.  The wire is made into a tube and filled with a flux which creates a shielding gas when it is melted by the heat of the welding arc.  For this reason, gasless wire can be used without a shielding gas and is an ideal problem solver if gas is not available.  Some DIY machines will only weld without gas too.

Aluminium MIG wire comes in a number of grades and should be matched, where possible to the parent material being welded together.  The most popular aluminium MIG welding wires are 4043 and 5356.  4043 contains silicon and provides a nice flowing weld puddle but is a soft wire, which can cause wire feed issues.  5356 is a bit harder and less malleable, containing magnesium.

Stainless MIG wire again comes in a number of grades, with the most popular being 316 and 308.  316 provides the highest level of corrosion resistance and can be used in marine and sanitary applications.  308 is a cheaper to purchase alternative and can be used where corrosion is less critical.  308 can be used to weld 304 grade Stainless material which is widely available from metal suppliers.

MIG Brazing wire is an ideal option for vehicle repair.  Different to MIG welding, brazing is a non fusion process meaning that the filler material is not introduced to the molten parent material.  The brazing wire has a lower melting point and joins materials.  This method is great for vehicle repairs where thin materials are often utilized, which would otherwise be prone to warping or burn through.  Heat can be kept minimal to prevent these issues from occurring.  Furthermore, MIG brazing wire can provide a strong join between dissimilar materials and high strength steels.

Our wires can be purchased on different size and weight spools.  Please be aware though, that the 1KG and 0.7KG spools have a small inner hub size and are for use with a hobby MIG welder, spool on gun or MIG welder with a hub adaptor installed.  5KG and 15KG MIG wire spools have the same size inner hub diameter.

Any of our wires can be purchased in bulk if required.  The benefit is the cost saving of doing so.  Pallet rates of SG2 MIG wire are available on request or consider using bulk drums of wire if using a lot.
