Stargon AL Welding Blend for Aluminum
™

Designed and Optimized for Aluminum GMAW and GTAW Processes
Praxair’s Stargon AL blend is a carefully prepared proprietary blend of argon with precisely controlled ppm (parts per
million) additions of active gases, and it is versatile for use in both GMAW and GTAW processes. When compared
to pure argon, Stargon AL blend provides better arc control, penetration and weld puddle placement, resulting in
improved weld speeds and weld quality.

By increasing arc stability, arc energy and overall arc performance, Praxair’s Stargon AL blend improves bead
appearance, can reduce the cleaning zone, and provides better wetting and weld penetration – increasing process
weld quality and operator appeal.
