A copper coated solid wire especially designed for downhill circumferential GMAW on pipes in materials such as APi 5L (grade 52 up to grade 70). The main applications are pipelines, compressor stations and associated works in the oil and gas distribution industries with special requirements. To meet these requirements the electrode is a "clean" type of EN ISO 14341-A G4Si1 as regards chemical analysis.
MIG Wires with Optimized Chemistry
Optimized chemistry for less post-weld rework make ESAB mild steel and low alloy MIG wires a good choice for overall cost of ownership.
Choose from a Family of Drum Sizes
Marathon Pac is ESAB's unique cardboard bulk drum system, available for a wide range of MIG wire grades. A complete family of drum sizes offers a solution for any kind of fabrication – from small workshops to large-scale manufacturing. Our largest drum is designed with reinforced corners and lifting straps for the most durable bulk wire drum package anywhere.
Excellent Feeding Performance
