Abstract

A welding-type device has a wireless communication unit 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 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, monitoring inventory, preventing theft of welding-type devices, and scheduling preventive maintenance.

Claims (11)

1. A welding-type consumable inventory system comprising:

at least one wireless monitoring device;

at least one welding-type consumable container having a consumable amount sensor and a wireless transmitter, the wireless transmitter configured to emit wireless signals having data encoded thereon indicative of a type and an amount of consumable in the container; and

wherein the at least one wireless monitoring device is arranged to find the at least one welding-type consumable container by receiving the wireless signals thereof.

2. The welding-type consumable inventory system of claim 1 further comprising a plurality of welding-type consumable containers configured to wirelessly transmit in an at least partial mesh network arrangement.

3. The welding-type consumable inventory system of claim 1 wherein the at least one welding-type consumable container comprises a shipment unit having an active transmitter and a number of individual units having passive transmitters.

4. The welding-type consumable inventory system of claim 1 wherein the at least one wireless monitoring device includes at least one of a directional radio frequency (RF) antenna, a GPS data reader, RF distance and angle measuring equipment, and RF signal-receipt time differentiation equipment.

5. The welding-type consumable inventory system of claim 1 wherein the at least one wireless monitoring device is arranged to determine whether the at least one welding-type consumable container is near a corresponding welding process, based upon consumable type and location.

6. The welding-type consumable inventory system of claim 1 wherein the consumable amount sensor is connected to sense a remaining amount of consumable of the container and update the consumable amount data for the wireless signal.

7. The welding-type consumable inventory system of claim 6 further comprising an inventory controller arranged to receive the data of the at least one welding-type consumable container via the at least one wireless monitoring device and programmed to determine at least one inventory total categorized by type of consumable.

8. The welding-type consumable inventory system of claim 7 wherein the inventory controller is further programmed to automatically generate a re-supply order when the at least one inventory total of welding-type consumable reaches a designated level determined by at least one of user setting, past re-supply levels, rate of usage, and estimated requirements.
