Abstract
PURPOSE: To obtain a controlling circuit that can change over welding conditions in a short time by providing ≥2 discharge routes for a capacitor, amplifying the electric current flowing in one of them with a transistor, and flowing large discharge current in the other route on account of this amplification thereby reducing the discharge time of the capacitor.
CONSTITUTION: This circuit consists of the 1st relay 2 connected to a DC electric power source 1, and controlling the supply of welding current between an electrode and the work, the 2nd relay connected to the power source 1, and controlling feeding of a welding wire, the 3rd relay 8 connected to the power source 1 and controlling the changeover of welding conditions and crater welding conditions, a current detecting relay for the current between the electrode and the work, a solenoid valve 10 for controlling the supply of shielding gas, a trigger switch 4 connected to the 2nd relay and controlling a sequence control timing, a capacitor 16 connected to the 3rd relay, a discharge resistance 17 and a transistor 31 connected to each of the 1st and 2nd discharge route of the capacitor and a charge resistance connected to the charge routes.
