The study discusses remote control torch system that is equipped with CO2 double wire reel. Thewelding machine is 30m away from the wire feeder at the industrial site and the feeder is three to fivemeters away from the torch. Accordingly, the welders cannot control the current and voltage that meetsthe welding condition during work when they are working at a place that prevents them from seeing thecontrol panel such as inside a vehicle or tank or at a far work site. They also have no choice but tostop working to change the wire reel when it is completely burned out. Such work suspension resultingfrom frequent moves to adjust current and voltage as well as replace the wire and subsequent coolingcauses welding defects. The study produced a remote control torch equipped with double wire reel bysimplifying and streamlining the existing CO2 functions to reduce the troubling issue. The remote controltorch equipped with double wire reel and the existing CO2 /MAG welding torch were applied asV-groove butt in the vertical position using 9mm rolled steel for SM50A welding structure. Aftercompletion of welding, the condition of welded surface beads went through visual inspection as well asradiographic inspection to analyze the welding quality inside the welded part. The study also evaluatedreduction of welding defects, cost saving, the replacing performance against the existing commercialwelders and the effect on possible compatibility.
