A DEVICE FOR AIR amp; ARC GOUGING EDGES OF MEMBERS OF METAL TO BE WELDED

摘要

A device for air and are gouging of edges of metal members to be welder together comprising a pair of oppositely driven rollers for feeding a carbon electrode, swivel plate for adjusting angle of inclination of the electrode relative to the metal member the edge of which is being gouged, and a nozzle, for blowing compressed air for removing the molten metal in the vicinity of the are formed between the electrode and the metal member the device being mounted on the electrically driven carriage the speed of which is controllable.
