Abstract

PURPOSE:To control a constant current even if a welding current exceeds the upper limit of a set value by the rapid change of an arc load by providing the PWM part operated by the command from a welding current and voltage detecting part in the welding machine using a power transistor. CONSTITUTION:A converting part 1 converts a welding current into a voltage. This converted voltage is proportional to the welding current. A welding current detecting part 2 sends a command to a PWM part 3 in case of the voltage fed from the converting part 1 exceeding the upper limit of the set value. The PWM part 3 having received this command shortens the conducting time of a transistor 5 by narrowing the output pulse width sending a driving command to the power transistor 5. An output voltage detecting part 4 sends a command to the PWM part 3 when the welding voltage exceeds the lower limit of the set value. The PWM part 3 having received this command shortens the conducting time of the transistor 5 by extending the output pulse period without changing the output pulse width sending a driving command to the transistor 5.
