AUTOMATIC ARC WELDING MACHINE EQUIPPED WITH AN AUTOMATIC STOPPER USING AN ARC SENSOR TO OVERLAP BEADS IN A TEMPORARY WELDING SECTION TO PROPERLY WELD THE BEADS

摘要

PURPOSE: An automatic arc welding machine equipped with an automatic stopper using an arc sensor is provided to prevent a welding fail by immediately stopping a welding carriage when the welding carriage separates from a welding line.;CONSTITUTION: An automatic arc welding machine comprises a current sensor unit(50) and a control device(60). The current sensor unit is installed in a welding power line(L1) of a single cable(C1) and outputs a sensing signal by detecting current. The control device is connected to the current sensor unit through a connection line(L3), receives the sensing signal from the current sensor unit, compares the sensing signal with a set reference current range, and immediately stops the operation of a welding carriage(30) when the output is out of the reference current range.;COPYRIGHT KIPO 2012
