Blue Demon ER70S-7 MIG Welding Wire

 

ER70S-7 is formulated for automotive sheet metal repair and fabrication, providing a low-profile weld bead and high post-weld workability on thin steel.

Material Properties and Chemistry

Compared to standard ER70S-6 MIG wire, ER70S-7 features an elevated manganese content. This chemical adjustment functions as a strong deoxidizer and increases the fluidity of the molten weld puddle.

Ideal Applications

  • Weld Profile: The increased fluidity of the ER70S-7 puddle causes it to wet out more readily, resulting in a flatter weld bead with a lower crown than standard wire.
  • Reduced Grinding: A flatter bead leaves less excess material above the panel surface, decreasing the time and abrasive material required to grind the weld flush.
  • Thermal Distortion Control: Shorter grinding durations generate less friction heat, which helps reduce the likelihood of heat-induced warping in thin sheet metal panels.
  • Planishing (Hammer and Dolly Work): The ER70S-7 weld deposit is less brittle than ER70S-6. The lower profile and structural ductility allow the joint to yield and stretch with less susceptibility to cracking when subjected to standard hammer and dolly work.
  • Application Note: For technicians and restorers seeking a replacement for the discontinued ESAB Spoolarc Easy Grind, ER70S-7 serves as a functional alternative with comparable puddle fluidity and grinding characteristics.
