HANDY LASER WELDING MACHINE AND CONTROL METHOD FOR HANDY LASER WELDING MACHINE

Document Type and Number:

WIPO Patent Application WO/2023/090299

Kind Code:

A1

Abstract:

A filler wire feeding machine (15) uses a motor (152) to feed out a filler wire (16). A motor driver (13) rotates the motor (152) in order to feed out the filler wire 16, and drives the motor (152) so as to stop the rotating motor (152). The motor driver (13) sets the absolute value of the positive rotational acceleration when the motor (152), the rotation of which has stopped, starts to rotate so as to be lower than the absolute value of the negative rotational acceleration when the rotating motor (152) stops rotating.
