Oerlikon Citorapid description: CITORAPID is a acid-ruytile coated MMA electrode featuring a high burn-off rate and a very high current carrying capacity. Therefore, it is particularly suited for piece-work applications. Suitable for welding primer painted and slightly rusted parts. Due to the low Si-content, welded components are suitable for subsequent galvanising, enamelling and rubber cladding. Weld joints are of X-Ray.
