Welding and gouging systems with multiple power settings

摘要

Embodiments of a welding power supply include a housing and a diesel engine disposed in the housing and adapted to output a first power output curve and a second power output curve substantially higher than the first power output curve. The welding power supply also includes a controller coupled to the diesel engine and adapted to control the diesel engine to operate along the first power output curve during a low power operation and to control the diesel engine to operate along the second power output curve during a high power operation.

主权项

1. A welding power supply, comprising:
a diesel engine having a first nominal setting operating at substantially 1800 RPM and a second nominal setting operating above substantially 1890 RPM; control circuitry coupled to the diesel engine and configured to control the diesel engine to operate along a first power output curve at the first nominal setting during welding operations and to operate along a second power output curve higher than the first power output curve at the second nominal setting during gouging operations; and a switch having a first selection for controlling the diesel engine to operate along the first power output curve at the first nominal setting at substantially 1800 RPM during the welding operations, and a second selection for controlling the diesel engine to operate along the second power output curve at the second nominal setting above substantially 1890 RPM during the gouging operations, wherein the switch is configured to be adjusted to the first selection and to the second selection by an operator, and wherein by selecting the first selection the operator selects the first nominal setting for the welding operations, and by selecting the second selection the operator selects the second nominal setting for the gouging operations.
