Hobart ER70S-3 MIG Welding Wire 0.030 in 11 lb

SKU CH-TWBQ-MC7GZ

Carbon-steel MIG wire in 0.030 in diameter on an 11 lb spool, rated for 70 ksi tensile and 58 ksi yield strength

  • Main materialCarbon Steel
  • Product typeER70S-3
  • 70 ksi tensile strength for strong carbon steel welds
  • 58 ksi yield strength resists deformation under load
  • 030 in diameter suits a wide range of MIG tasks
  • 11 lb plastic spool feeds smoothly through the gun
  • ER70S-3 classification matches general fabrication needs

Hobart ER70S-3 Carbon Steel Wire

Hobart ER70S-3 MIG welding wire is supplied as an 11 lb plastic spool of 0.030 in diameter carbon steel filler metal. The wire carries AWS classification ER70S-3 and is intended for joining carbon steel to carbon steel using DCEP polarity.

For flat, horizontal, overhead and vertical welding

This spool suits fabricators and maintenance welders who need a general-purpose carbon steel wire for flat, horizontal, overhead, vertical-down and vertical-up positions. It does not suit applications requiring a different alloy classification, a larger or smaller wire diameter, or a non-DCEP current designation.

70 ksi tensile strength as welded

The wire delivers a minimum required tensile strength of 70 ksi and a minimum required yield strength of 58 ksi, with as-welded values matching those figures. That 70 ksi tensile rating is the primary specification that determines whether this filler metal meets the joint design requirements.

Questions about this item

What does the 70 ksi tensile strength mean once the wire is in a real machine?

The 70 ksi tensile strength is the as-welded value the joint must reach; it matches the AWS ER70S-3 minimum required tensile strength.

Which wire diameter should I choose for this spool?

This spool is supplied only in 0.030 in diameter; choose it when your MIG gun and drive rolls are set for that size.

What welding current and positions does the ER70S-3 classification cover?

The wire is designated for DCEP current and qualified for flat, horizontal, overhead, vertical-down and vertical-up positions.
