Superior Abrasion Resistance with Smooth, Reliable Performance
The Cigweld Cobalarc 750 is a premium rutile-type hardfacing electrode, engineered for AC or DC welding setups, particularly excels in mobile or field environments. Designed for AC hard surfacing, especially on portable welders with an open circuit voltage of ≥ 45 V, it delivers smooth, stable arcs and exceptional wear resistance.
Key Benefits:
-
Outstanding Abrasion Resistance
Delivers a martensitic steel deposit with a hardness of approximately 750 HV30, offering excellent protection against hard particle wear. -
Air-Hardening, Crack-Free Layer
Creates an air-hardening deposit with minimal distortion or cracking, ensuring long-lasting performance. -
Reliable Arc and Easy Ignition
Starts effortlessly and maintains stable arc control, even on portable AC machines — ideal for remote or site work. -
Efficient Use in Thin Applications
Best applied with a touch or short arc technique; one to two layers offer optimal hardness.
