109 HS™ High-Strength Dual-Phase Electrode
109 HS is excellent for thick-to-thin joints with superior all-position welding characteristics when compared to most alloy steel electrodes.

• Minimal precleaning — welds through grease, rust, paint, and even steels that have moisture on them
• Dual-phase — welding characteristics will change depending on the current used, allowing the welder complete control over the joining process
• Excellent for small AC machines
• Penetrating arc on DC, but soft on AC
• Easy slag removal
