CIGWELD WELDSKILL 312 Product Data Sheet
An ESAB Brand
Product Overview
WELDSKILL 312 electrodes are highly alloyed stainless steel electrodes designed for welding all types of steels. They are resistant to cracking and offer excellent arc starting and stability, even on low Open Circuit Voltage (O.C.V.) welding machines. The rutile type flux coating provides smooth, stable running in all positions (except vertical down) and is particularly effective at low current settings.
The weld deposit offers excellent resistance to corrosion and oxidation. WELDSKILL 312 is recommended for the repair and maintenance of steels, especially those with unknown compositions. It is suitable for joining dissimilar steels (e.g., stainless to carbon steel), repairing die or tool steels, and for use as a protective overlay or an intermediate buffer layer prior to hard surfacing.
These electrodes are available in handy-packs suitable for smaller projects.
Power Settings: AC / DC+ | 45 OCV
