AA R400

Category 
type 
Seamless copper coated rutile flux-cored wire for CO2 and M21.
applications 
Shipbuilding, steel and vessel construction, mechanical engineering and pipe work.
Properties 

Seamless fluxcored wire with excelent welding properties in all positions. Due to the seamless concept this wire offers full protection against moisture pickup and can be stored for longer periods. AA R400 offers the best possible feeding properties that allows you to use longer torches. Applicable  for hand and (semi)-mechanized welding. Good performance down to -40°C. Low spatter loss and excelent slag removal. Also suitable for welding on ceramic backing and root runs without backing
