Low Hydrogen

JACKSUN 18

AWS A5.1: E7018

Premium basic coated, low-hydrogen electrode for structural, pressure vessel, boiler, and pipeline applications.
Provides X-ray quality welds with excellent mechanical strength and toughness.
Very low hydrogen content, ensuring resistance to cracking.
Smooth and stable arc, easy slag removal, and excellent bead appearance.
Suitable for all-position welding except vertical down.
Runs well on AC and DC+, including low OCV machines.
