Method and apparatus for welding

A welding power supply, comprising:

• a source of power;
• a CC controller connected to the source of power;
• a CV controller connected to the source of power;
• and
• a pulse controller connected to the source of power;
• and
• a sequence controller connected to the CC controller, and connected to the CV controller and connected to the pulse controller, wherein the sequence controller first activates the CC controller, then activates the CV controller, and then activates the pulse controller.

A system for initiating a pulse welding process at a welding location, comprising:

• means for initiating a welding arc by providing CC type welding power, disposed to provide power to the welding location;
• means for maintaining the arc by providing CV type power, disposed to provide power to the welding location;
• and
• means for thereafter providing pulse type welding power, disposed to provide power to the welding location.

A welding power supply, comprising:

• power means for providing power;
• CC control means for controlling the power means to provide CC type power, connected to the source of power;
• CV control means for controlling the power means to provide CV type power, connected to the source of power;
• and
• pulse controller means for controlling the power means to provide pulse type power connected to the source of power;
• and
• a sequence controller means for controlling the sequence of the welding start, connected to the CC controller, and connected to the CV controller and connected to the pulse controller, whereby the sequence control means first activates the CC controller, then activates the CV controller, and then activates the pulse controller.

A method of initiating a welding process of a given welding mode, comprising:

• initiating a welding arc by providing CC type welding power;
• maintaining the arc by providing CV type power;
• and
• thereafter providing welding power in the given welding mode, wherein the given mode is not a CV mode.

A welding power supply for providing given mode, comprising:

• a source of power;
• a CC controller connected to the source of power;
• a CV controller connected to the source of power;
• and
• a short circuit controller connected to the source of power;
• and
• a sequence controller connected to the CC controller, and connected to the CV controller and connected to the short circuit controller, wherein the sequence controller first activates the CC controller, then activates the CV controller, and then activates the short circuit controller.

A system for initiating a short circuit welding process at a welding location, comprising:

• means for initiating a welding arc by providing CC type welding power, disposed to provide power to the welding location;
• means for maintaining the arc by providing CV type power, disposed to provide power to the welding location;
• and
• means for thereafter providing short circuit type welding power, disposed to provide power to the welding location.

A welding power supply for providing a given mode of welding power, comprising:

• power means for providing power;
• CC control means for controlling the power means to provide CC type power, connected to the source of power;
• CV control means for controlling the power means to provide CV type power, connected to the source of power;
• and
• a final controller means for controlling the power means to provide the given mode of power, wherein the given mode is not a CV mode, connected to the source of power;
• and
• a sequence controller means for controlling the sequence of the welding start, connected to the CC controller, and connected to the CV controller and connected to the final controller, whereby the sequence control means first activates the CC controller, then activates the CV controller, and then activates the final controller.
