High productivity and overall cost management is obtained by:
High welding speeds
Excellent penetration profiles
Extra low spattering
Excellent pool appeal

High quality results are due to:
Controlled impurity level
Consistent and homogeneous mix
Extra low humidity and oxygen levels particularly in plasma or TIG processes

Four ready-to-weld argon mixture solutions cover virtually all welding application needs. Each mixture was designed to be reliable and simple, yet high performing.



ARCAL™ Prime is our primary high-quality shielding product for most welding situations, including TIG and plasma welding of all materials such as titanium, MIG welding of aluminum and copper alloys, and universal root shielding of all materials. 99.999% argon ensures reliable integrity of the weld bead making ARCAL™ Prime the pure gas solution for your arc welding needs.
