Overview
The Praxair PRSP308L17128 ProStar E308/308L-17 stick electrode is a premium consumable for arc welding of austenitic stainless steels. This chromium-nickel covered electrode with acid rutile coating is designed for welding of low carbon 18% Cr/10% Ni austenitic stainless steels, making it a trusted choice for fabricators and maintenance professionals requiring consistent, high-quality welds.
Key Features
- Excellent arc stability, low spatter, fast burn-off rate with minimal stub loss, and improved moisture resistance
- Smooth, flat to concave weld deposit with smooth spray transfer arc and easy-to-remove slag cover
- Works in any standard weld position
- Alloy identification embossed on each rod end for ease of identity even after the rod is partially consumed
- Supplied in VacPac packaging to maintain quality
- Self-peeling slag for efficient cleanup and finishing
