HB-28
AWS A5.18: ER70S-6
Hobart HB-28 is a copper-coated, mild steel solid wire that is formulated with a high deoxidizer content to provide excellent welding performance with 100% CO2 and mixed gases. HB-28 produces an exceptionally smooth and stable arc with minimal spatter and offers good wetting characteristics that allow for uniform tie-ins. It is an excellent choice when welding with very slow to moderately fast wire feed speeds.
