Abstract

PURPOSE: To prevent water from freezing in the cooling water line and damaging apparatus by branching the cooling water line used for arc welders, etc. and expelling the water of the cooling water line, etc. with compressed air.
CONSTITUTION: A hose 11 connected to gas source 10 is connected to a gas source 19 on the way of the cooling water supply hose 5a of a welding torch 2. Solenoid valves 13, 14 are mounted to the gas line hose 11 and cooling water supply hose 5a, respectively. When the use of the welding torch 2 is finished, the solenoid valves 13, 14 are operated to send the compressed air from the gas source 10 to the supply hose 5a and torch 2. Since the water in the hose 5a and welding torch 2 is expelled by the compressed air, there is no possibility of damaging by freezing.
