COMPLEX CABLE INCLUDING POWER WIRE, SIGNAL WIRE, AIR PRESSURE HOSE, AND COOLING HOSE IN ONE CABLE USED IN SPOT WELDING BY ROBOT ARM

摘要

PURPOSE: A complex cable used in a spot welding by a robot arm is provided to prevent a power wire, a signal wire, an air pressure hose, and a cooling hose from being damaged by putting the above elements into one cable. CONSTITUTION: A complex cable used in a spot welding includes a power wire(10) for providing welding power supplied from an exterior to a spot gun. A signal wire(20) is provided to control a movement of the spot gun and to detect a signal. A cooling water hose(30) provides cooling water to reduce heat generated when the spot gun performs welding work. An air pressure hose(40) transfers air pressure to upper and lower electrodes of the spot gun. A water leakage detecting wire(50) detects a water leakage generated due to the damage of the cooling water hose(30).
