The flux feed and recovery system are mounted high above the pipe welding stations. Flux feed is accomplished with a gravity or compressed air system. The recovery system recovers the unused flux from the welding point, removes slag particles and flux flour and sends the slag-free flux back to the flux hopper. All this operation is accomplished a continuous automatic operation. To insure efficient separation of reusable flux from slag and flux flour, the system is equipped with a dual separator system. The primary separator isolates slag and fused particles and enhances removal of flux flour. It also acts as a collection hopper for unused flux.
