A recovery type flux feeding assembly is disclosed. The assembly includes a virgin flux hopper and a waste flux hopper with a flux feed conduit connected to the bottom of the waste flux hopper. The hoppers are separated by a drop stop which selectively permits flux from the virgin flux hopper to enter the waste flux hopper so that the flux exiting through the flux feed is a mixture of the two. A flux return assembly consists of a flux recovery port positioned adjacent the waste flux from the weld, a cyclone attached to the top of the waste flux hopper and a conduit connecting the two. An air injector injects air into a midpoint of the conduit between the flux recovery port and the cyclone so that the cyclone is kept at a positive pressure and the waste flux therein is not sucked out. Conduits are included between the tops of the hoppers for equalizing the pressures therebetween. In one embodiment, the virgin flux hopper surrounds and is entirely above the waste flux hopper while in another embodiment the two are adjacent and on substantially the same level.

A motor-driven welding machine capable of holding and carrying a welding torch stably along a welding line, the machine including adjusting means for varying the mounting position of a welding torch or the inter-axle distance of carriage wheels according to the type of the welding torch to be held thereon. The machine further includes means for allowing or stopping oscillatory or pivotal movements of the welding torch in horizontal and vertical planes and means for steering the carriage wheels in relation with the oscillatory movements of the torch.
