Abstract

PURPOSE: To make possible the remote putting on or off of the power source to be carried out safely, by detecting the compressed air flow on the way of the path connecting the compressed air source and the torch, and by controlling the output of the welding power source so as to be put on or off.
CONSTITUTION: In case of the gouging work and the blasting work, prior to the start of the arc, the compressed air flow is injected against the parent metal 7 by the actuator 13, and the air flow in the compressed air hose 11 is detected by the detector 14, and the power source switch of the welding power source 2 is closed through the control cable 15, and the arc 9 is started to begin the work. When the work is finished, the carbon electrode 8 is separated from the parent metal 7 to extinguish the arc 9, and the actuator 13 is actuated to stop the compressed air flow in the compressed air hose 11. As a result, the compressed air flow detector 14 is actuated so as to open the power source switch of the welding power source 2 through the control cable 15, hereby, no voltage is remained across the carbon electrode 8 and the parent metal 7, which secures the safety until the next work is started.
