Abstract
In embodiments, a welding apparatus includes an automated wire feed mechanism to output wire at a wire feed rate, where the wire is to provide a welding arc to a weld site. The wire feed rate is based at least in part on selected power to be provided to the weld site. Additional embodiments are described and claimed.
Claims18
A welding apparatus comprising:
- an automated wire feed mechanism to output wire at a wire feed rate, wherein a direction of wire feed of the automated wire feed mechanism is reversible;
- wherein a wire extremity of the wire is to provide a welding arc between the wire extremity and a weld site, and
- wherein responsive to an indication to cease welding, the welding arc is extinguished by retraction of the wire extremity into a non-conductive sleeve, wherein the retraction is effected by reversal of the direction of wire feed of the automated wire feed mechanism.
A welding system comprising:
- a wire feed mechanism to output weld wire at a wire feed rate, wherein the weld wire is to enable welding by conducting electrical current to a weld site;
- a welding tip to receive the weld wire from the wire feed mechanism and from which a weld wire extremity is output to provide a welding arc to a weld site;
- controller circuitry to determine the wire feed rate of the wire feed mechanism based on input from a user;
- a current sensor to provide information to the controller circuitry,
- wherein the controller circuitry is to adjust the wire feed rate based at least in part on the information received from the current sensor;
- and
- a battery to provide weld power for the welding arc,
- wherein the wire feed mechanism, the welding tip, the control circuitry and the battery are enclosed in a hand-held portable enclosure, wherein the welding apparatus is configured to be operated by a hand of a user while the hand-held portable enclosure is held by the hand of the user.

A method comprising:
- determining, by controller circuitry, a feed rate of a wire feed mechanism that is configured to feed wire to a weld site of a weld circuit, wherein the wire is to provide welding power to the weld site, wherein the welding power is received from a portable energy supply;
- and
- responsive to receiving, by the controller circuitry, an indication of an energy supply threshold reached by the portable energy supply, stopping a feed of the wire feed mechanism to stop the welding wire from providing the welding power to the weld site;
- and
- responsive to the indication of the energy supply threshold received by the controller circuitry, reversing a direction of feed of the wire to cause a tip of the wire to retract into a weld tip.
