Abstract
An example welding system includes: power conversion circuitry configured to: output welding-type power to a weld circuit; and output preheating power to a preheater; and control circuitry configured to: receive an input selecting one of a plurality of weld schedules, each of the plurality of weld schedules specifying a combination of a welding-type output power and a preheating output power; and control the power conversion circuitry to output the welding-type power and the preheating power based on the selected one of the plurality of weld schedules.
Claims21
A welding system, comprising:
- power conversion circuitry configured to:
- output welding-type power to a weld circuit;
- and
- output preheating power to a preheater;
- and
- control circuitry configured to:
- receive an input selecting one of a plurality of weld schedules, each of the plurality of weld schedules specifying a combination of a welding-type output power and a preheating output power;
- and
- control the power conversion circuitry to output the welding-type power and the preheating power based on the selected one of the plurality of weld schedules.
6 more elements
