Approaches herein provide a system for determining whether one or more consumable parts of a plasma device has been removed or replaced while the plasma device and associated sensors lie dormant or are no longer receiving data, e.g., when the plasma device is power-off. The approaches herein determine whether certain types of data stored in a controller's memory are still valid, for example, for the purposes of determining degradation and/or end-of-life of the consumable parts. In the case that one or more consumable parts has been serviced or replaced, the data stored in the controller memory may no longer be considered valid for the consumable part(s). In one approach, the controller determines a status of a switch or a conformal film in the device following start-up, and determines, based on the position of the switch or the conformal film, whether the consumable part has been removed or replaced.

Plasma device consumable part change detection

An automated plasma cutting system is provided that includes a positioning system mounted to a support, an automated plasma arc torch mounted to the positioning system, and at least one power supply operatively connected to the automated plasma arc torch. The power supply may provide electrical power and fluid flow to the automated plasma arc torch for operation. The system further includes a controller in communication with the automated plasma arc torch and the power supply, and an auxiliary plasma arc torch operatively connected to the power supply, wherein the power supply provides electrical power and fluid flow to both the automated plasma arc torch and the auxiliary plasma arc torch. The automated plasma arc torch may process the workpiece to generate a set of features, while the auxiliary plasma arc torch may process/cut a residual framework of the workpiece remaining after formation of the set of features.

Automated gas cutting system with auxiliary torch

A system and method for generating a weld are provided. The system receives a selection of a magnitude of a voltage. The system selects a first weld control algorithm when the magnitude of the voltage is in a first range of values. The system may also select a second weld control algorithm when the magnitude of the voltage is in a second range of values. The system may generate welding output power based on the first and second weld control algorithms.

Method for selection of weld control algorithms

Systems and methods for providing an improved start in a welding process are provided. The system may include a power circuit and a control circuit. The power circuit can generate a welding output power. The control circuit may be in communication with the power circuit to control, during the start of the welding process, at least one welding parameter until the control circuit determines that welding energy output exceeds an energy output threshold.

Initiation of welding arc by restricting output

Systems and methods for providing an improved start in a welding are provided. The system may include a power circuit and a control circuit: The power circuit may generate welding output power for a welding process. The control circuit may control the start of the welding process, for example, by generating a current pulse.

Method to improve process stabilization

A system and method for generating a weld are provided. A power circuit in communication with a control circuit generates welding output voltage. A voltage reducing circuit in communication with the power circuit generates a reduced output voltage relative to the welding output voltage if the system determines that the welding process is idle for the predefined period of time. The welding output voltage is restored from the reduced voltage if the welding process is restarted.

Energy conservation and improved cooling in welding machines

A system and method is provided for calculating a power output and coordinating the reduction of voltage and wire speed. Specifically, provided is a power circuit for generating welding output power, and a control circuit in communication with the power circuit to modify voltage and wire feed speed based on the calculated welding output power.

Modification of control parameters based on output power

A system and a method are provided for improved run-in control during a start of a welding process. A power circuit generates welding output power. A control circuit in communication with the power circuit controls the output power. The control circuit receives a selection of a wire feed speed setting representing a wire feed speed. The control circuit receives a selection of a run-in setting representing a run-in percentage of the wire feed speed. The control circuit determines an effective run-in percentage that is equal to the run-in percentage plus an extra percentage.
