Patent

CA 2265278

A microprocessor based controller with a JAVA virtual machine used to control a specific electric arc welder having a switching type power supply for creating a welding cycle with a real time current waveform constituting several control parameters by rapidly switching a D.C. current in a controlled fashion by a pulse width modulator, which controller displays a waveform generated on an electrically operated waveform screen; allowing manual adjustment of at least a portion of the waveform displayed on the waveform screen to generate a new waveform on the waveform screen; and, operating the pulse width modulator to cause the power supply to create a real time waveform corresponding to the new waveform to execute the control parameters by the electric arc welder.
