Arcaloy 309L-17 Plus electrodes utilize a heavy coating to maximize performance in the flat and horizontal position. Usable on AC or DC current.
Arcaloy 309L-17 Plus electrodes have a heavy coating and produce a concave bead with minimal ripple. The slag is virtually self-cleaning. For welding carbon steel to stainless steel for service below about 600°F (315ºC) and for the first layer when cladding.
