Eastwood .045 Inch ER70S-2 Filler Rod 1LB – ER70S2-045-01T Top Sell

ER70S-2 is the most popular and versatile rod used for welding 4130 chrome moly tubing as well as all mild steel and even cast steel. The main reason for its popularity is because it produces high quality welds, even when the metal is dirty, oily or even rusty. It provides x-ray quality welds with no porosity while having the highest tensile strength of all plan carbon steel filler rods. It is high in manganese and silicon and this chemistry increases the fluidity of the weld puddle, creating a better bead and less grinding.

How To Select Filler Rod

045” diameter filler rod for thin sheet metal

1/16” diameter filler rod for welding metal 1/8” thick or less

3/32” diameter filler rod for welding metals thicker than 1/8”.

ER70S-2 – Mild steel and 4130 chrome moly tubing

4043 – Aluminum

ER308L – Stainless Steel

Silicon Bronze – Used for brazing and even combining dissimilar metals like copper to steel
