Abstract

A portable welder that includes a portable housing, a ground clamp, an electrode holder, a user interface, and a battery pack interface. The ground clamp is connected to the portable housing through a ground cable and is configured to be connected to a metal workpiece. The electrode holder is connected to the portable housing through an electrode cable. The electrode holder includes a mount connected to the electrode cable and a user input. The mount is configured to hold a consumable electrode. The user input is configured to activate the portable welder. The user interface located on the housing. The battery pack interface is configured to receive a removable and rechargeable battery pack.

Claims (43)

1. A portable welder comprising:

a portable housing;

a ground clamp connected to the portable housing through a ground cable, the ground clamp configured to be connected to a metal workpiece;

an electrode holder connected to the portable housing through an electrode cable, the electrode holder including a mount connected to the electrode cable, the mount configured to hold a consumable electrode, and

a user input configured to activate the portable welder;

a user interface located on the housing;

a battery pack interface configured to receive a removable and rechargeable battery pack; and

a wireless communication controller configured to wirelessly communicate with an external device separate from the portable welder,

wherein a setting of the portable welder is controlled based on a signal received from the external device.

2. The portable welder of claim 1 , wherein the user interface displays a state-of-charge of the battery pack.

3. The portable welder of claim 1 , wherein the setting of the portable welder is an ON or OFF state of a security lockout system.

4. The portable welder of claim 1 , wherein the portable welder is configured to be powered by between a 200 Watt-hour battery pack and a 1000 Watt-hour battery pack.

5. The portable welder of claim 4 , wherein the portable welder controls operation of a fan based on a temperature associated with the portable welder.

6. The portable welder of claim 5 , wherein the fan of the portable welder is controlled to turn ON based on a first temperature threshold and to turn OFF based on a second temperature threshold.

7. A portable welder comprising:

a portable housing;

an electrode holder connected to the housing through an electrode cable, the electrode holder including:

a consumable electrode;

a mount connected to the electrode cable, the mount configured to hold the consumable electrode, and

a user input configured to activate the portable welder;

a user interface located on the housing;

a battery pack interface configured to receive a removable and rechargeable battery pack; and

a wireless communication controller configured to wirelessly communicate with an external device separate from the portable welder,

wherein a setting of the portable welder is controlled based on a signal from the external device.

8. The portable welder of claim 7 , wherein the user interface displays a state-of-charge of the battery pack.

9. The portable welder of claim 7 , wherein the setting of the portable welder is an ON or OFF state of a security lockout system.

10. The portable welder of claim 7 , wherein the portable welder is configured to be powered by between a 200 Watt-hour battery pack and a 1000 Watt-hour battery pack.

11. The portable welder of claim 7 , wherein the portable welder controls operation of a fan based on a temperature associated with the portable welder.

12. The portable welder of claim 11 , wherein the fan of the portable welder is controlled to turn ON based on a first temperature threshold and to turn OFF based on a second temperature threshold.

13. The portable welder of claim 12 , wherein the first temperature threshold is different from the second temperature threshold.

14. The portable welder of claim 7 , wherein the portable welder determines a remaining runtime of the portable welder based on a state-of-charge of the battery pack.

15. A portable welder comprising:

a portable housing;

an electrode holder connected to the housing through an electrode cable, the electrode holder including:

a consumable electrode;

a mount connected to the electrode cable, the mount configured to hold the consumable electrode, and

a user input configured to activate the portable welder;

a user interface located on the housing;

a battery pack interface configured to receive a removable and rechargeable battery pack; and

a wireless communication controller configured to wirelessly communicate with an external device separate from the portable welder.

16. The portable welder of claim 15 , wherein a setting of the portable welder is controlled based on a signal from the external device.

17. The portable welder of claim 16 , wherein the setting of the portable welder is an ON or OFF state of a security lockout system.
