Ultramag S4 is your first choice when welding on metals with a low to medium presence of surface contaminants such as rust or mill scale. Ultramag S4 MIG wire has all of the advantages of Ultramag S3, with slightly higher levels of manganese and silicon. It has higher "cleaning" levels, and produces a more fluid weld puddle and flatter bead profile.Ultramag S4 has an excellent reputation for feedability and trouble-free performance.
Advantage Lincoln
.• Highly resistant to copper flaking, which can clog liners and contact tips.
• Copper coating provides superior arc-starting characteristics, for long contact tip life.
• MicroGuard surface treatment is designed to provide smooth trouble-free feeding performance.
• Well suited for applications where accurate and consistent wire feed are necessary.
• Manufactured under a quality system certified to ISO 9001 requirements.
• Manufactured under a global environmental quality system certified to ISO14001 requirements.
Typical Application
• Applications which require greater cleaning action through increased levels of silicon and maganese compared to the levels provided by a typical ER70S-3 wire.
• Industrial, farming, construction, and mining equipment.
• Single pass welds on sheet metal applications.
• Multiple pass welds on thick steel sections.
• For welding on base material with light to medium surface rust or mill scale.
• All-position welding.
