Background of the invention
The invention relates generally to welding systems and more particularly to a voltage sensing wire feeder having memories of welding procedures.
Welding is a process that has become increasingly prevalent in various industries and applications. These processes can be automated in certain contexts, although a large number of applications continue to exist for manual welding applications. In both cases, these welding applications rely on a variety of equipment types to ensure that the supply of welding consumables (e.g., wire, shielding gas, etc.) is provided to the weld in an adequate quantity in the desired moment. For example, metal inert gas (MIG) welding typically relies on a wire feeder to enable a welding wire to reach a welding torch. The wire is continuously fed during welding to provide filler metal. A power source ensures that arc heating is available to melt the filler metal and the underlying base metal.
Voltage sensing wire feeders are a type of wire feeder powered by the use of welding energy provided from a welding power source, thus obviating the use of a separate wire to power the sensing wire feeder. voltage. Thus, the number of cables running between the voltage sensing wire feeder and the welding power source may be less than in
IMPI
INSTITUTO MEXICANO DI LA MONEDAD INDUSTRIAL
<img file="MX347268B_D0004.tif" />
systems that use a wire feeder that is not a voltage sense wire feeder. In a system having a non-voltage sensing wire feeder, the cable that energizes the wire feeder may include several isolated conductive lines to carry data between the wire feeder and the welding power source. In addition, a non-voltage sensing wire feeder (eg, constant speed wire feeder) may include processes and / or features that operate based on communication between the wire feeder and the welding power source. Consequently, while voltage sense wire feeders obviate the use of a separate cable between the voltage sense wire feeder and the welding power source, voltage sense wire feeders may typically be unable to communicate. with the welding power source.

In one embodiment, a voltage sensing wire feeder includes a storage device and a user interface configured to receive a first selection and a second selection. The first selection is configured to direct the voltage sensing wire feeder to use a first group of settings stored in the storage device, and the second selection is configured to direct the voltage sensing wire feeder to use a second group. settings stored on the storage device.
In another embodiment, one method includes receiving a selection, in a voltage sensing wire feeder, from among several groups of settings stored in a storage device of the voltage sensing wire feeder.

In another embodiment, a welding system includes a welding power source configured to provide welding power for a welding application. The welding system also includes a welding cable and voltage sensing wire feeder that has various groups of settings stored in a voltage sensing wire feeder storage device. The voltage sensing wire feeder is configured to receive welding energy from the welding power source on the welding cable, and to communicate with the welding power source on the welding cable. Each of the groups of settings is at least partially dependent on communication between the voltage sensing wire feeder and the welding power source.

Detailed description of the invention
Turning now to the drawings, Figure 1 is a block diagram of one embodiment of a welding system 10 that employs devices that enable communication between a welding power source and a voltage sensing wire feeder. In the illustrated embodiment, welding system 0 is a metal inert gas welding (MIG) system, although the present techniques can be used in other welding systems, such as other gas metal arc welding (GMAW) systems. ), and so on. The welding system 10 powers, controls and supplies consumables to a welding application. The welding system 10 includes a welding power source 12 and a voltage sensing wire feeder 14 (eg, not a constant speed wire feeder).
Welding power source 12 receives primary power 16 (eg, from the AC mains, a motor / generator assembly, a battery, or other energy generation or storage devices, or a combination thereof) conditions primary power, and provides an output power to one or more welding devices in accordance with the demands of system 10. Primary power 16 may be supplied from an off-site location (i.e., the
<img file="MX347268B_D0007.tif" />
primary energy can originate from the electrical grid). Accordingly, the welding power source 12 includes power conversion circuits 18 that may include circuit elements such as transformers, rectifiers, switches, and so on, capable of converting AC input power to AC output power or CC as dictated by the demands of System 10 (eg, particular welding regimes and processes). These circuits are generally known in the art.
In some embodiments, the power conversion circuit 18 may be configured to convert the primary power 16 into both welding and auxiliary power outputs. However, in other embodiments, the energy conversion circuit 18 may be adapted to convert primary energy to only one welding energy output, and a separate auxiliary converter may be provided to convert primary energy to auxiliary energy. Also, in some embodiments, the welding power source 12 may be adapted to receive a converted auxiliary power output directly from a wall outlet. In fact, any suitable energy conversion system or mechanism can be employed by the welding power source 12 to generate and supply both welding and auxiliary power.
The welding power source 12 includes a control circuit 20 for controlling the operation of the welding power source 12. The welding power source 12 also includes a user interface 22. The control circuit 20 can receive input from the user interface 22 through which<sub>k</sub> a user can select a process and enter desired parameters (eg, particular voltages, currents, pulsed or non-pulsed welding regimes, and so on). The user interface 22 can receive input using any input device, such as via a numeric keypad, keyboard, buttons, touch screen, input system,
<img file="MX347268B_D0008.tif" />
voice activation, wireless device, etc. In addition, the control circuit 20 can control parameters entered by the user as well as any other parameters. Specifically, user interface 22 may include a visual presenter 24 for presenting, displaying, or indicating information to an operator. Control circuit 20 may also include interface circuitry to communicate data to other devices in system 10, such as voltage sensing wire feeder 14. Welding power source 12 includes transceiver 26 to communicate seamlessly. cordless 28 with other welding devices. In the illustrated embodiments, the welding power source 12 can communicate with other welding devices using a wired connection, such as by using a network interface controller (NIC) 30 to communicate data over a network 32 ( for example, the internet.
A gas source 34 provides shielding gases, such as argon, helium, carbon dioxide, and so on, depending on the welding application. Shielding gas flows to a valve 36, which controls gas flow and if desired can be selected to allow modulating or regulating the amount of gas supplied to a welding application. Valve 36 may be open, closed, or otherwise operated by control circuit 20 to enable, inhibit, or control gas flow through valve 36. For example, when valve 36 is closed, it may be inhibited. shielding gas to flow through valve 36. Conversely, when valve 36 is open, shielding gas can be allowed to flow through valve 36. In certain embodiments, welding system 10 may control valve 36 such that data is communicated from welding power source 12 to voltage sensing wire feeder 14 using data encoded within flux fluctuations (e.g. example, through gas pulses within
INS-MEXICAN WALL OF THE PHOWECAD OF THE GAS FLOW). Shielding gas exits valve 36 and flows through hose 38 (which in some implementations may be impaled with solid welding energy) to a voltage sensing wire feeder 14 that provides shielding gas. to welding application. As can be appreciated, certain embodiments of welding system 10 may not include gas source 34, valve 36, and / or hose 38.
Welding energy flows through a wire 40 to voltage sensing wire feeder 14. Voltage sensing wire feeder 14 uses welding energy to power the different components in voltage sensing wire feeder 14 , such as to power control circuit 42. Welding power source 12 can also communicate with voltage sensing wire feeder 14 using wire 40. For example, welding power source 12 and / or voltage sensing wire feeder 14 may use welding wire communication (WCC) in which data is provided on welding power such that power and data solder are provided together using a single conductor. Accordingly, the welding power source 12 includes a circuit 39, and the wire feeder 14 includes a circuit 41 to facilitate communication using transmission between the welding power source 12 and the wire feeder 14. Thus, using a cable 40, welding power can be provided from the welding power source 12 to the voltage sensing wire feeder 14, and the welding power source 12 can communicate with the voltage sensing wire feeder. voltage 14.
The control circuit 42 controls the operations of the voltage sensing wire feeder 14. The control circuit 42 includes at least one controller or processor 43 that controls the operations of the voltage sensing wire feeder.

For example, processor 43 may include one or more reduced instruction set (RISC) processors.

The storage device 44 can store data (eg, data corresponding to a welding application, one or more welding procedure memories, etc.), instructions (eg, software or firmware to carry out welding processes) , and any other suitable data. As can be appreciated, data corresponding to a welding application can include the altitude (i.e., orientation) of a welding torch, a distance between the contact tip and a workpiece, a voltage, a current, settings of the welding device, and so on.

In addition, voltage sensing wire feeder 14 may include a second selectable input configured to recall a second group of settings that correspond to the second selectable input after selection of the second selectable input.

Memory device 45 may include volatile memory, such as random access memory (RAM), and / or non-volatile memory, such as read-only memory (ROM). The memory device 45 can store a variety of information and can be used for various purposes. For example, memory device 45 may store per-processor executable instructions (eg, firmware or software) for processor 43 to execute.

In certain embodiments, the voltage sensing wire feeder 14 also includes a transceiver 46 for wirelessly communicating 48 with the welding power source 12, or other device (eg, either directly or over a network). In certain embodiments, the transceiver 46 may be a Bluetooth device configured to communicate wirelessly with other devices. In certain embodiments, transceiver 46 can be used to transmit and / or receive welding procedure memories to and / or from another device for storage, archiving, and so on. Additionally, receiver 46 can be used to transmit and / or receive data records, error codes, error information, or any other suitable data.

A contactor 54 (eg, high amperage relay) is controlled by control circuit 42 and is configured to enable or prevent welding energy to flow to a welding power cable 56 for the welding application. In certain embodiments, contactor 54 may be an electromechanical device, while in other embodiments, contactor 54 may be any other suitable device, such as a solid state device. The voltage sensing wire feeder 14 includes a wire driver 58 that receives control signals from the control circuit 42 to drive rollers 60 that rotate to pull wire off of a wire spool 62. The wire is provided to the welding application through a cable 64. Likewise, the voltage sensing wire feeder 14 can provide shielding gas through a cable 66. As can be seen, cables 54, 64 and 66 can be grouped together with a coupling device 68.
A torch 70 supplies the wire, welding power, and shielding gas for a welding application. The torch 70 is used to establish a welding arc between the torch 70 and a work piece 74. A work cable 76, which can be terminated with a clamp 78 (or other power connection device), couples the source. of welding power 12 to workpiece 74 to complete the welding power circuit. As illustrated, a voltage sense wire 80 is coupled from voltage sense wire feeder 14 to workpiece 74 using a sense clamp 82 (or other power connection mechanism). Consequently, voltage sensing wire feeder 14 is connected to welding power source 12 in such a way that it can operate even when no welding arc is formed by torch 70. Specifically, the<sup>12</sup>

A return path for the power from the voltage sense wire feeder 14 is formed using the voltage sense wire 80 with the sense clamp 82 connected to the work piece 74. In addition, the work wire 76 with the clamp The work path 78 provides the final portion of the return path to the welding power source 12. In this manner, the return path includes the cable 80, the workpiece 74, and the cable 76. As can be appreciated, the welding energy can flow in any direction through the conductive path formed by cables 40, 56 and 76.
Generally, wire feeders are either constant speed wire feeders (for example, wire feeders powered using a single substantially unchanging DC voltage or AC voltage provided over a dedicated power control cable, such as a 14 conductor cable with two conductors providing power and the remaining conductors providing control signals), or voltage sensing wire feeders (e.g. powered wire feeders using welding energy provided over a welding cable). A voltage sensing wire feeder can be powered by either a constant voltage (CV), a constant current (CC), an AC or DC welding power source. With a voltage sensing wire feeder and CV power source, the voltage is adjusted at the power source while the wire feed speed (amperage) is adjusted at the voltage sensing wire feeder.

OF THE PROPERTY
As described above, typically, a voltage sensing power supply does not include the ability to communicate with the welding power torch 12 because the voltage sensing wire feeder is powered using wire 40 (except systems in which an additional cable runs between the welding power source 12 and the wire feeder - in systems having such additional cable, communication between the welding power source 12 and the wire feeder is commonly limited by the number of conductors in the additional cable (eg, 14 conductors in a 14 conductor cable). However, as described herein, voltage sensing wire feeder 14 can communicate with welding power source 12 in a variety of ways without using an additional wire that runs between welding power source 12 and voltage sensing wire feeder 14 (and communication can be advanced over systems that use a dedicated communication cable because the communication described herein does not limit the type or amount of data communicated). For example, welding power source 12 and voltage sensing wire feeder 14 can communicate using WCC by providing power and welding data together over welding power cable 40. As another example, the power source of Welding 12 and voltage sense wire feeder 14 can communicate wirelessly using transceivers 26 and 46. In addition, the welding power source 12 and the voltage sensing wire feeder 14 may communicate together through a connection to the network 32 (eg, via the internet). Furthermore, welding power source 12 can communicate with voltage sensing wire feeder 14 using a flow of gas through gas hose 38 (for example, through gas pulses within the gas flow ). Each of these communication methods does not use a cable that runs between the

Consequently, typical voltage sensing wire feeders are not capable of, and do not include, memories of welding procedures, at least partially because typical voltage sensing wire feeders do not have adequate means to enable communication between the 12 welding power source and voltage sensing wire feeders. In contrast, the voltage sensing wire feeder 14 includes selected welding procedure memories and facilitates communication between the welding power source 12 and the voltage sensing wire feeder 14 to use the welding procedure memories. For example, a welding procedure memory may include a power supply voltage setting. Thus, when the welding procedure memory is selected, the voltage sensing wire feeder 14 can provide the power supply voltage setting to the welding power source 12. As another example, a welding procedure memory may include data that corresponds to a process (e.g., flux cored arc welding (FCAW), no shielding gas, MIG with shielding gas, FACAW with shielding gas, Pulsed MIG, 6010 Rod, 7108 Rod, Lift Arc TIG, Scratch Start TIG, Air Carbon Arc Grouping (ACAG), Remote Lift Arc TIG, etc.) or sequence (for example, pre flow, input, arc shock, welding, crater, bumback, post-flow, etc.) in which the welding power source 12 and the voltage sensing wire feeder 14 work together. The data that pertains to the process can include one or more voltage settings, current settings, wire speed, time, and so on.

As described herein, voltage sensing wire feeder 14 may include one or more welding process memories.
Additionally, voltage sensing wire feeder 14 can be configured to communicate with welding power source 12 to carry out welding applications that correspond to welding procedure memories without using a dedicated power / control cable (separate welding cable 40) coupled between voltage sensing wire feeder 14 and welding power source 12. Consequently, a number of wires running between the welding power source 12 and the voltage sensing wire feeder 14 can be kept to a minimum number, but the voltage sensing wire feeder 14 can include characteristics of a non-voltage sensing wire feeder (for example, a constant speed wire feeder).
Although only certain features of the invention have been illustrated and described herein, many modifications and changes will occur to those skilled in the art. Therefore, it should be understood that the appended claims are intended to cover all such modifications and changes that fall within the true spirit of the invention.
