Method and system for collecting fume and/or waste particulate matter generated in a process used to surface treat, cut, gouge or join a workpiece by means of elevated temperature (e.g. electric arc). The system includes means to collect and quench the effluent (slag and/or fume) in a cooled nozzle coupled with means to separate solid particles and cooling fluid, in the case of a working environment including air and return cleansed air to the ambient environment.

Apparatus for collecting process generated fume and/or slag

Method and system for collecting fume and/or waste particulate matter generated in a process used to surface treat, cut, gouge or join a workpiece by means of elevated temperature (e.g. electric arc). The system includes a nozzle for collecting the slag and fume. The nozzle is cooled by fluid. In addition there is a filter to separate particles and to return clean air to the ambient.

Method for collecting process generated fume and/or slag

An automatic air-carbon arc cutting and gouging torch having a drive for the elongated electrode consisting of opposed wheels biased toward the electrode for frictional contact to drive the electrode by driving one of the wheels. Each wheel can be adjusted about a pivot point to compensate for curvature of the electrode, changes in diameter, or mis-aligned joints in successive electrodes. The torch includes an improved nozzle to conduct both current and process air to the electrode thus lowering the operating temperature of the torch.

Air-carbon arc cutting and gouging torch

A fixed head air-carbon arc cutting and gouging torch for use in a metal foundry for cleaning riser pads, sprues, fins and other excess or unwanted surface material or defects from castings. The torch is characterized by improved air flow means to reduce the required inlet air pressure, improved air valve means, better head angle and handle design for increased process efficiency.
