LINCOLN ELECTRIC CHINA LOW ALLOY GMAW WIRE

PRODUCT FEATURES

·Excellent weldability - Stable arc, low spatter, low clean up, suitable for both short-circuit transfer and high current spray transfer.

·Superb feedability - Unique manufacturing technology results in a clean wire surface, smooth copper coating layer and an even amount of feeding lubricant. These advantages ensure lower friction during wire feeding and better electrical conductivity.
