UV 420 TTRC is an agglomerated fluoride-basic flux with highand field of use basicity and neutral metallurgical behavior. UV 420 TTRC is a special variant of flux UV 420 TTR. It supports the C-content of the wire electrode when DC-welding. In comparison with UV 420 TTR the C-content in the all weld metal is about 0.03-0.04% higher. It is suitable for multipass welding, for single and tandem-wire systems
