Key features
- Advantageous in confined spaces and with limited fume extraction systems
- It exhibits outstanding, almost spatter-free, welding properties and produces finely rippled flat and smooth welds which are free of undercut
- Very easy slag removal
- Due to its fast-freezing slag, it can be used for welding in the horizontal (PD), overhead (PE) and vertical-up (PF) positions.
