Abstract
An extension arm for attachment to a resistance welding hand piece is disclosed. The extension arm may include an elongated main body extending between a first end and a second end. The first end of the elongated main body may be attachable to the hand piece such that the second end of the elongated main body is spaced apart from the hand piece. The extension arm also may include an electrode extending from the second end of the elongated main body. The electrode may be in electrical communication with the hand piece by way of at least one electrical pathway.
Claims16
An extension arm for attachment to a hand piece of a handheld welding tool for resistance welding, wherein the hand piece comprises a handle portion that is graspable and maneuverable by a user, the extension arm comprising:
- an elongated main body extending between a first end and a second end, wherein the first end of the elongated main body is attachable to the hand piece via a fastener such that the second end of the elongated main body is spaced apart from the hand piece, wherein the elongated main body is tapered from the first end to the second end;
- an electrode extending from the second end of the elongated main body, wherein the electrode is in electrical communication with the hand piece by way of at least one electrical pathway, wherein the electrode is substantially transverse to a longitudinal axis of the elongated main body;
- and
- a leverage arm extending from the first end of the elongated main body substantially transverse to the longitudinal axis of the elongated main body and in a direction opposite the electrode, wherein a distal end of the leverage arm extends into a slot in the hand piece.
A system for resistance welding, the system comprising:
- a hand piece of a handheld welding tool for resistance welding, wherein the hand piece comprises a handle portion that is graspable and maneuverable by a user;
- and
- an extension arm attachable to the hand piece, the extension arm comprising:
- an elongated main body extending between a first end and a second end, wherein the first end of the elongated main body is attachable to the hand piece via a fastener such that the second end of the elongated main body is spaced apart from the hand piece, wherein the elongated main body is tapered from the first end to the second end;
- an electrode extending from the second end of the elongated main body, wherein the electrode is in electrical communication with the hand piece by way of at least one electrical pathway, wherein the electrode is substantially transverse to a longitudinal axis of the elongated main body;
- and
- a leverage arm extending from the first end of the elongated main body substantially transverse to the longitudinal axis of the elongated main body and in a direction opposite the electrode, wherein a distal end of the leverage arm extends into a slot in the hand piece.
A method for resistance welding, the method comprising:
- providing a hand piece for resistance welding, wherein the hand piece comprises a handle portion that is graspable and maneuverable by a user;
- and
- attaching an extension arm to the hand piece, the extension arm comprising:
- an elongated main body extending between a first end and a second end, wherein the first end of the elongated main body is attachable to the hand piece such that the second end of the elongated main body is spaced apart from the hand piece, wherein the elongated main body is tapered from the first end to the second end;
- an electrode extending from the second end of the elongated main body, wherein the electrode is in electrical communication with the hand piece by way of at least one electrical pathway, wherein the electrode is substantially transverse to a longitudinal axis of the elongated main body;
- and
- a leverage arm extending from the first end of the elongated main body substantially transverse to the longitudinal axis of the elongated main body and in a direction opposite the electrode, wherein a distal end of the leverage arm extends into a slot in the hand piece.
