摘要
A portable machine for electric arc welding and air carbon arc gouging on vertical wall surfaces is disclosed. A table-mounted carriage arm carrying a vertical positioning assembly for welding nozzles or a gouging torch is driven horizontally around a vertical axis of rotation while guide wheels on the carriage arm traverse the wall surface or traverse a flexible guide secured to the machine table through a system of support arms when a rough wall surface is involved. The carriage arm is biased yieldingly toward the wall surface during its horizontal traverse and the vertical positioning assembly adjusts itself automatically on its vertical axis to maintain proper welding nozzle and gouging torch alignment with the wall surface undergoing repair. A constant speed of movement of welding nozzles or a gouging torch across the wall surface is maintained. The welding nozzles or gouging torch are motor-driven vertically on the positioning assembly.
