Tip: Copper-free surfaces can help reduce unplanned stops by minimizing feeding issues in automated systems.
Features
Features & application areas
Used in welding of constructions, machinery, ships, tanks, boilers, pipes, thin sheets, bodies, steel furniture and metal accessories made of unalloyed, general structural and fine-grained steels—also widely used in the automotive industry. Depending on base metal classification, CO₂ or mixed gases (Ar+CO₂) can be used as shielding gas.
Trouble-free feeding
Helps prevent spiral, torch and contact tip blockages.
High arc stability
Consistent arc behavior for repeatable production welds.
Reduced spatter
Cleaner welds with less dross and post-weld cleanup.
Efficient processes
Reduced consumable consumption and steadier uptime.
Operating temperature range: 350°C to 400°C.
