Abstract
A welding system and method includes a main torch including a main electrode configured to form a first arc with a base metal; a first bypass torch including a first bypass electrode configured to form a second arc with the main electrode; and a second bypass torch including a second bypass electrode configured to form a third arc with the main electrode.
Claims38
A welding system comprising:
- a main torch including a main electrode configured to form a first arc with a base metal;
- a first bypass torch including a first bypass electrode configured to form a second arc with the main electrode;
- and
- a second bypass torch including a second bypass electrode configured to form a third arc with the main electrode.
The welding system of claim further comprising:
- a switch in series with the first bypass electrode, the switch having a first position and a second position, wherein when in the first position the second arc is generated and in the second position the second arc is not generated.
A welding system comprising:
- a main torch including a main electrode configured to form a first arc with a base metal;
- a first bypass torch including a first bypass electrode configured to form a second arc with the main electrode;
- and
- a contact tube configured to feed consumable wire to form a third arc with the main electrode.
A welding system comprising:
- a main torch including a main electrode configured to form a first arc with a base metal;
- a first bypass torch including a first bypass electrode configured to form a second arc with the main electrode;
- a second bypass electrode configured to form a third arc with the main electrode;
- and
- a composite torch housing configured to substantially surround the main electrode, the first bypass electrode and the second bypass electrode.
A control method for a welder having a main channel, a first consumable bypass channel, and a second non-consumable bypass channel, the method comprising:
- providing a first constant voltage to the main channel;
- providing a second constant voltage to the first consumable bypass channel;
- and
- providing a constant current to the second non-consumable bypass channel.
