Abstract
A torch assembly for cutting or spraying applications. The torch assembly includes a torch connector that connects to at least one cable that communicates with a power supply. The torch assembly includes a trigger mounted on the torch assembly to start and stop torch operations. The trigger electrically communicates with the power supply via the at least one cable. The torch assembly also includes a remote switch mounted on the torch assembly to allow an operator to remotely adjust an output of the power supply to a desired output level. The remote switch is electrically coupled to the power supply via the at least one cable.
Claims19
A torch assembly for cutting or spraying applications, the torch assembly comprising:
- a torch connector that connects to at least one cable that communicates with a power supply having a first predetermined output level that is a user-selected nominal output level of the power supply or a maximum output level of the power supply;
- a trigger mounted on the torch assembly to start and stop torch operations, the trigger configured to electrically communicate with the power supply via the at least one cable;
- and
- a mechanical limiter mounted on the torch assembly and linked to the trigger and configured to remotely set an output power of the power supply to a second predetermined output level that is different from the first predetermined output level by mechanically limiting displacement of the trigger, wherein the mechanical limiter includes means for adjusting the second predetermined output level,
- wherein, when the trigger is depressed and the mechanical limiter has been engaged, the output of the power supply is limited to the second predetermined output level, and
- wherein, when the trigger is depressed and the mechanical limiter has not been engaged, the output of the power supply is the first predetermined output level.
A cutting or spraying system, the system comprising:
- a power supply having a first predetermined output level that is a nominal output level selected by a user using a user interface on the power supply or a maximum output level of the power supply;
- and
- a torch assembly, the torch assembly comprising,
- a torch connector that connects to at least one cable that communicates with the power supply,
- a trigger mounted on the torch assembly to start and stop torch operations, the trigger configured to electrically communicate with the power supply via the at least one cable, and
- a mechanical limiter mounted on the torch assembly and linked to the trigger and configured to set an output of the power supply to a second predetermined output level that is different from the first predetermined output level by mechanically limiting displacement of the trigger, wherein the mechanical limiter includes means for adjusting the second predetermined output level,
- wherein, when the trigger is depressed and the mechanical limiter has been engaged, the output of the power supply is limited to the second predetermined output level, and
- wherein, when the trigger is depressed and the mechanical limiter has not been engaged, the output of the power supply is the first predetermined output level.
