ＩＧ溶接機。 In a TIG welding machine that uses pulsed current and has a torch vertical drive mechanism and an arc length controller that keeps the arc length constant during welding, the arc length controller has a circuit that determines the peak period and base period of the pulsed current, and welding. A circuit that determines whether welding has just started or is continuing welding, a memory that stores the voltages of the peak period and the base period, and a comparison circuit that compares the voltages of the peak period and the base period are provided. Memorize the base voltage,
A T characterized in that it is configured to thereafter use these voltages as reference voltages to perform arc length control for both the peak and base periods of the pulse current.
IG welding machine.
