Abstract

PURPOSE: Arc welding machine, enable to obtain both characteristics of constant- voltage and drooping by one machine carrying out change-over of output characteristic simply, by connecting autotransformer with primary winding of insulating transformer through change-over switch.
CONSTITUTION: Primary, secondary common connecting side of the autotransformer 2 having the sliding mechanism 3, is connected with the secondary winding of the insulating transformer 1 through the change-over switch 4. The autotransformer 2 is made constant-voltage transformer when the switch 4 is made ON for A side and output electric power is made variable by sliding the mechanism 3 and then, constant-voltage characteristic output is obtained. The autotransformer 4 is acted as alternating current reactor and drooping characteristic output is obtained. By the above mechanism, adjustment and change-over of output characteristic are able to carry out simply and stable arc welding is able to carry out by input from single phase power source.
