Recently, gas shielded metal arc welding (GMAW) process is widespread in shipbuilding, instead of covered electrodes.As this reason, GMAW process is superior to covered electrodes on the welding efficiency, mechanization and rationalization.But, there are many problems to be solved on application of GMAW process in shipbuilding.One of the problems is the guarantee of long-distance wire feedability.This “DS FEEDER” was developed for welding fabrication in shipbuilding and its features are as follows.1) This feeder is composed of DS FEEDER unit (pull feeder), long-distance cable and its control unit.2) Long-distance cable length is max. 20 meters and its cable is composed of wire conduit tube, welding power cable, shielding gas circuit, and control cables as one body.3) Long-distance cable is smaller outer diameter (max. 25.5mm) and has a suitable flexibility.4) DS FEEDER unit (pull feeder) is easy to handle and smaller size.5) The control unit is suitable to push-pull wire feeding system and guarantee the long-distance wire feedability.
