Abstract

PURPOSE: To obtain always stable arc starting characteristics by setting the wire feed speeds v1, v2 at the arc starting and at the steady time at nearly a fixed linear relation and controlling v1 higher or lower than v2 depending upon whether v2 is lower or higher than 4 to 6m/min.
CONSTITUTION: When the wire feed speed v2 at the steady time is lower than 4 to 6m/min (vc), the set potential of a variable resistance VR is lower than the Zener voltage of a Zener diode ZD. Here, the diode ZD is nonconducting and ZD1 conducts. The signal Vm to a motor control circuit becomes of a value higher than the potential determined by the resistance VR and the foregoining v1 becomes the straight line (a), hihger than v2. If at this time the value of the resistance R3 is made large, v1 becomes like the straight line (b). When v2>vc, the set potential of the resistance VR is higher than the Zener potential of the diozde ZD, where said ZD1 is nonconducting and ZD conducts. Then, the foregoining Vm becomes of a value lower than the potential determined by the resistance VR and the foregoining v1 becomes like the straight line (c). If at this time the value of the resistance R2 is increased, the v1 becomes like the straight line (d).
