Abstract

A portable welder including a housing, a power supply contained within the housing, a welding cable having a proximal end and a distal end, the proximal end of the welding cable being electrically connected to the power supply, a welding electrode that extends from the distal end of the welding cable, and a control system that adjusts welding current delivered to the welding electrode from the power supply based on user input.

Claims

1. A portable welder comprising:

a housing;

a power supply contained within the housing;

a welding cable having a proximal end and a distal end, the proximal end of the welding cable being electrically connected to the power supply;

a welding electrode that extends from the distal end of the welding cable; and

a control system that adjusts welding current delivered to the welding electrode from the power supply based on user input.

2. The portable welder of claim 1, wherein the power supply comprises at least one battery.

3. The portable welder of claim 2, wherein the at least one battery is a Sealed-Lead Acid (SLA) battery.

4. The portable welder of claim 3, wherein the at least one battery is an Absorbed Glass Matt (AGM)-type SLA battery.

5. The portable welder of claim 1, further comprising a ground cable electrically connected to the at least one battery.

6. The portable welder of claim 1, wherein the control system comprises a welding control electrical circuit.

7. The portable welder of claim 6, wherein the welding control electrical circuit comprises a potentiometer that is adjusted by the user to control current delivered to the welding electrode from the power supply.

8. The portable welder of claim 1, further comprising a wire feed motor that drives the welding electrode through the welding cable.

9. The portable welder of claim 8, further comprising a welding gun disposed at the distal end of the welding cable.

10. The portable welder of claim 9, wherein the wire feed motor is contained within the welding gun.

11. The portable welder of claim 8, wherein the wire feed motor is contained within the housing.

12. The portable welder of claim 1, wherein the welding electrode is a stick electrode.

13. The portable welder of claim 1, wherein the housing comprises a handle for transporting the portable welder.
