General Description

The new generation AS SG2 CF non-copper coated GMA welding wires offer significant improvements in quality and productivity, meaning that users can reduce the cost of manual, mechanised or especially robotic (full automatic) welding operations.

Due to its non-copper coated and improved quality wire surface, AS SG2 CF avoids the contamination problems associated with copper coatings such as build-ups on wire feeder units (drive rollers, guides etc...), liners, torches and contact tips. This results in trouble-free feeding, a high process stability, reduced consumption of spare-parts and superior welding properties.

AS SG2 CF non-copper coated GMA welding wire also allows a stable arc when working with increased welding speeds and gives high-quality welds with almost no-spatter. A further advantage of AS SG2 CF is that it produces less fume, which keeps the working environment cleaner.
