A welding machine includes a main housing with head stock and tail stock sections at its opposite ends having respective chucks for supporting a rotating work piece. A carriage movable endwise between the head stock and tail stock sections includes a head overlying the work area and a flux collection tray and associated circulation components underlying the carriage head and the work area. A welding torch assembly is supported in suspended adjustable relation from the carriage head and includes a welding tip through which weld wire is fed and a dispensing nozzle surrounding and concentric with the welding tip for dispensing granulated flux. Granulated flux is supplied by gravity from a hopper in the carriage head; and the flux is circulated from the hopper box under the collection tray to the overhead flux hopper by a pneumatic circulating system.'
