Filler metals for every common arc welding process. This section covers solid MIG wire such as ER70S-6 for mild steel, self-shielded and gas-shielded flux-cored wire, stick electrodes including E6010, E6011, E6013 and E7018, TIG cut-length filler rod, stainless steel wire and rod such as ER308L and ER316L, aluminum wire such as ER4043 and ER5356, hardfacing electrodes, and tungsten electrodes for TIG torches. Spools, coils, tubes and cans come in a range of sizes.

What to check before you order

  • Process. Make sure the product is made for MIG, flux-core, stick or TIG, and for AC or DC polarity as your machine runs.
  • Base metal. Match the filler to the steel, stainless or aluminum grade you are joining. Follow the welding procedure where one is specified.
  • Diameter and spool size. Common MIG wire sizes are 0.023", 0.030", 0.035" and 0.045". Check the spool hub size fits your welder.
  • Storage. Low-hydrogen electrodes such as E7018 must be kept dry. Many shops store them in a rod oven once opened. Keep wire covered to prevent rust.
  • Shielding gas. Solid wire needs the right gas mix. Self-shielded flux-core needs none.

Common questions

What is the difference between ER4043 and ER5356 aluminum wire?

ER4043 flows easily and is less prone to cracking. ER5356 gives higher strength and a better color match after anodizing. Pick based on the alloy and the job.
