Characteristics and field of use
TIG welding rod， copper coated for welding in boiler making， pressure vessel and pipeline construction，
crane building and steel construction. High-quality， very tough and crack-resistant weld metal， resistant
to ageing. Suitable for the temperature range from -30°C to 500°C (550°C). Very good welding and
flow behaviour.
