A GAS SUPPLY AND WIRE FEEDING CABLE FOR CO2 ARC WELDING

摘要

The present invention relates to gas supply for carbon dioxide gas arc welding and wire feed cable. The present invention relates to a large-capacity cylindrical pail pack (3) in which a welding wire (2) is rolled up and rolled; A welding wire feeding device 4 formed on the fail pile 3 for correcting / sending out the wire 2; A welding cable (5) providing voltage and current; A gas supply and wire feeding cable 6; A control cable 7 of the welding wire delivery device 4; A gasifier 9 for feeding the welding wire 2 fed from the fail pack 3 to the welding torch 8 and a hose for supplying gas to the welding torch 8 from the gas container, In the device 1, The gas supply and wire feeding cable 6 for feeding the wire 2 rolled up to the fail pack 3 to the feeder 9 and supplying the gas to the welding torch 8 in the gas container, A gas supply passage is formed with a liner 15 formed of an acetal tube to which the wire 2 is fed in the center of the inner diameter and gas supply valves 14a and 14b are formed at both ends. The present invention is characterized in that a liner is provided inside a cable for smoothly feeding a wire embedded in a large-capacity fail-pack constituting a carbon dioxide gas arc welding device to a feeder to which a welding torch is connected, wherein a space is provided between the liner and the wire feeding cable And gas supply and wire feeding are performed by one cable by supplying gas for welding.
