Abstract
A welder for welding a base metal. The welder may include a first electrode for forming a first arc with the base metal and a second electrode for forming a second arc between the first and second electrodes. A compact welder, welding system, and method are also provided.
Claims14
A welding system, comprising:
- a gas metal arc welder having a first electrode for forming a first arc between the first electrode and a base metal to be welded;
- a gas tungsten arc welder having a second electrode for forming a second arc between the second electrode and the first electrode, such that a value of a current through the base metal is less than a value of the current through the first electrode.
A welding system, comprising:
- a gas metal arc welder having a first electrode for forming a first arc between the first electrode and a base metal to be welded;
- a gas tungsten arc welder having a second electrode for forming a second arc between the second electrode and the first electrode;
- and
- a means for controlling the value of a current through the base metal at a level less than a value of the current through the first electrode.
1 more element
A welding system comprising:
- a gas metal arc welder having a consumable electrode for carrying a first current and for forming a first arc between the consumable electrode and a base metal to be welded;
- and
- a gas tungsten arc welder having a non-consumable electrode for carrying a second current and for forming a second arc between the non-consumable electrode and the consumable electrode;
- wherein the base metal carries a third current with a lower value than the first current, and wherein the sum of the second and third current is equal to the first current.
1 more element
A welding system for use with a welding power supply, said system comprising:
- a gas metal arc welder having a first electrode for receiving a current from the power supply and for creating a first arc between the first electrode and a base metal to be welded;
- and
- a gas tungsten arc welder having a second electrode for receiving a first portion of the current from the first electrode and for forming a second arc between the second electrode and the first electrode;
- wherein the base metal receives a second portion of the current from the first electrode.
