Abstract

A welder guard system is disclosed. According to various embodiments of the concepts and technologies described herein, the welder guard system can include a base and a lid attached to the base. The welder guard system can also include a safety switch system having an actuating device and a sensing device. The actuating device can be attached to the lid of the welder guard system and can provide a wireless signal. The sensing device can cause a welding device to prevent a welding jaw of the welding device from closing in response to activation of a clamping operation of the welding device when the sensing device fails to receive the wireless signal provided by the actuating device.

Claims (26)

1. A welder guard system comprising:

a base;

a lid attached to the base;

a control unit for a welding device; and

a safety switch system comprising an actuating device and a sensing device, wherein the actuating device is attached to the lid, wherein the actuating device comprises a transmitter that transmits a wireless signal, wherein the sensing device comprises a transmitter and a receiver that receives the wireless signal transmitted by the transmitter of the actuating device when the lid is in a closed position and fails to receive the wireless signal transmitted by the transmitter of the actuating device when the lid is in an open position, wherein the transmitter of the sensing device sends a signal to the control unit when the receiver of the sensing device fails to receive the wireless signal transmitted by the transmitter of the actuating device, and wherein the control unit, in response to the signal from the transmitter of the sensing device, prevents a welding jaw of the welding device from closing in response to activation of a clamping operation of the welding device to close the welding jaw.

2. The welder guard system of claim 1 , wherein the lid comprises a frame having a top portion and a front portion.

3. The welder guard system of claim 2 , wherein the actuating device is attached to a bottom of the front portion of the frame of the lid.

4. The welder guard system of claim 2 , wherein the lid further comprises a plurality of pinch point guards, wherein a first pinch point guard of the plurality of pinch point guards is attached on one side of the top portion of the frame of the lid, and wherein a second pinch point guard of the plurality of pinch point guards is attached on an opposing side of the top portion of the frame of the lid.

5. The welder guard system of claim 4 , wherein the plurality of pinch point guards move with the lid and relative to the base when the lid is moved from the open position to the closed position and from the closed position to the open position.

6. The welder guard system of claim 2 , wherein the top portion of the frame of the lid houses a top panel, and wherein the front portion of the frame of the lid houses a front panel.

7. The welder guard system of claim 1 , wherein the receiver of the sensing device fails to receive the wireless signal transmitted by the transmitter of the actuating device when the actuating device is moved, via movement of the lid from the closed position to the open position, outside of a sensing range of the receiver of the sensing device.

8. The welder guard system of claim 1 , wherein the control unit comprises a solenoid valve.

9. The welder guard system of claim 8 , wherein the solenoid valve of the control unit causes a port associated with a flow of compressed air to the welding jaw of the welding device to close in response to the signal from the transmitter of the sensing device, blocking a supply of the compressed air to the welding jaw and preventing the welding jaw from closing.

10. The welder guard system of claim 1 , wherein the base comprises a body, a first side, and a second side, wherein the first side of the base comprises an arm, wherein the second side of the base comprises an arm, and wherein the arm of the first side of the base and the arm of the second side of the base receive the lid only when the lid is placed in the open position.

11. A welder guard system comprising:

a base;

a lid attached to the base;

a control unit for a welding device; and

a safety switch system comprising an actuating device and a sensing device, wherein the actuating device is attached to the lid, wherein the actuating device comprises a piece of conductive metal, wherein the sensing device comprises a transmitter and an inductive proximity sensor that produces an electromagnetic field, wherein the inductive proximity sensor detects the actuating device when the lid is in a closed position causing the actuating device to be within the electromagnetic field of the inductive proximity sensor and fails to detect the actuating device when the lid is in an open position causing the actuating device to be outside of the electromagnetic field of the inductive proximity sensor, wherein the transmitter of the sensing device sends a signal to the control unit when the inductive proximity sensor fails to detect the actuating device, and wherein the control unit, in response to the signal from the transmitter of the sensing device, prevents a welding jaw of the welding device from closing in response to activation of a clamping operation of the welding device to close the welding jaw.

12. The welder guard system of claim 11 , wherein the lid comprises a frame having a top portion and a front portion.

13. The welder guard system of claim 12 , wherein the actuating device is attached to a bottom of the front portion of the frame of the lid.

14. The welder guard system of claim 12 , wherein the lid further comprises a plurality of pinch point guards, wherein a first pinch point guard of the plurality of pinch point guards is attached on one side of the top portion of the frame of the lid, and wherein a second pinch point guard of the plurality of pinch point guards is attached on an opposing side of the top portion of the frame of the lid.

15. The welder guard system of claim 14 , wherein the plurality of pinch point guards move with the lid and relative to the base when the lid is moved from the open position to the closed position and from the closed position to the open position.

16. The welder guard system of claim 11 , wherein the control unit comprises a solenoid valve.

17. The welder guard system of claim 16 , wherein the solenoid valve of the control unit causes a port associated with a flow of compressed air to the welding jaw of the welding device to close in response to the signal from the transmitter of the sensing device, blocking a supply of the compressed air to the welding jaw and preventing the welding jaw from closing.

18. The welder guard system of claim 11 , wherein the base comprises a body, a first side, and a second side, wherein the first side of the base comprises an arm, wherein the second side of the base comprises an arm, and wherein the arm of the first side of the base and the arm of the second side of the base receive the lid only when the lid is placed in the open position.
