摘要:
A system for providing a dynamically controlled plasma cutting system. The plasma cutting system includes a proportional valve and a sensing device arrangement and a controller connected to this arrangement. The system is configured to dynamically control gas flow in a plasma torch. The system measures gas pressure at a proportional valve and makes necessary gas pressure adjustments in the system by way of controlling a drive signal sent to the proportional valve to control gas flow.
摘要:
A welding-type device (84) has a wireless communication unit (86) to transmit wireless signals comprising at least identification information (92) or location information (106). The information may be transmitted either automatically or in response to request signals. Such a welding-type device (84) may be configured to communicate with other welding-type devices, a monitoring device, or both. A wireless communication system has at least one welding-type device (84), at least one wireless communication assembly (86), and at least one monitoring device (112) and is capable of assisting a user in locating particular welding-type devices, monitoring inventory, preventing theft of welding-type devices, and scheduling preventive maintenance.
摘要:
A welding system includes a power supply coupled to a power source and configured to receive a power signal. The power supply includes power conversion circuitry having one or more silicon-controlled rectifiers (SCRs) and configured to rectify the power signal to generate a DC signal for use in providing welding power. The welding system also includes an SCR detection system configured to receive a signal indicative of an inductor current of the DC signal and a signal indicative of a voltage of the DC signal. The SCR detection system is further configured detect a non-firing, open, or shorted SCR in the one or more SCRs based on the inductor current and the welding voltage of the DC signal.
摘要:
A heat input control method for a welding system includes the step of receiving data encoding a desired heat input range having heat input values included between an upper limit and a lower limit. The method also includes the step of receiving data encoding a desired change to a level of a first weld variable of a set of weld variables. Further, the method includes determining a change to a level of a second weld variable of the set of weld variables. The determined change to the level of the second weld variable is suitable to maintain a heat input of a welding operation within the desired heat input range.

A welding-type device has wireless communications to transmit wireless signals comprising at least identification information or location information. The information may be transmitted either automatically or in response to request signals. Such a welding-type device (10) may be configured to communicate with other welding- type devices, a monitoring device, or both. A wireless communication system has at least one welding- type device, at least one wireless communication assembly, and at least one monitoring device and is capable of assisting a user in locating particular welding-type devices, preventing theft of welding- type devices, and scheduling preventive maintenance .
