Abstract
A welding gun adapted to secure a contact tip within the welding gun without threading the contact tip and without the use of tools. The contact tip may be adapted to abut a surface of a first member disposed within the welding gun. The surface may be a surface of a gas diffuser. The surface may be adapted to abut the contact tip. The contact tip also may be adapted for abutment with a second member to urge the contact tip toward the first member. The second member may be a portion of a nozzle adapted to abut the contact tip to urge the contact tip toward the surface of the first member. A method of assembling a welding gun also is provided. The method may include disposing a contact tip between a first and a second member and capturing the contact tip between the first and second members.
Claims49
A welding gun for an arc welding system, comprising:
- a gas diffuser comprising a first member;
- a nozzle comprising a second member disposed coaxially with the first member, wherein the first and second members are independent from one another;
- and
- a contact tip disposable coaxially with the first member and the second member, wherein at least part of the contact tip is axially compressed between the first and second members.
A welding gun for an arc welding system, comprising:
- a gas diffuser comprising a first member;
- a nozzle comprising a second member disposed coaxially with the first member, wherein the first and second members are configured to move axially relative to one another while coupled to the welding gun;
- and
- a contact tip disposable coaxially with the first member and the second member, wherein the contact tip comprises first and second surfaces axially biased in opposite inward directions by the respective first and second members, and the second surface comprises a shoulder extending around the contact tip.
A welding gun for an arc welding system, comprising:
- a first member;
- a second member disposed coaxially with the first member, wherein the second member comprises a nozzle and an annular insert disposed within the nozzle, and the first and second members are independent and movable relative to one another;
- and
- a contact tip disposable coaxially with the first member and the second member, wherein at least part of the contact tip is axially compressed between the first member and the annular insert of the second member, and the annular insert comprises a plurality of gas delivery holes extending therethrough to enable gas to flow through the nozzle in parallel with the contact tip.
A welding gun for an arc welding system, comprising:
- a gas diffuser comprising a first member;
- a nozzle comprising a second member axially displaceable relative to the first member;
- and
- a contact tip disposed intermediate the first and second members,
- wherein the contact tip is secured to the welding gun by axial compression of at least part of the contract tip between the first member and the second member, and the contact tip is threadless.
A welding system, comprising:
- a nozzle, comprising a first portion adapted for abutment with a contact tip to urge the contact tip towards a first surface located opposite the first portion, such that the contact tip is axially compressed between the nozzle and another member of the welding system, wherein the nozzle is independent from the contact tip and the other member of the welding system.
A welding system, comprising:
- a gas diffuser, comprising a tapered surface adapted for abutment with a corresponding surface of a contact tip, such that the contact tip is axially compressed between the gas diffuser and another member of the welding system, wherein the gas diffuser is independent from the contact tip and the other member of the welding system.
A method of assembling a welding gun, comprising the acts of:
- disposing a contact tip between a gas diffuser secured to the welding gun and a nozzle securable to the welding gun;
- and
- securing the nozzle to the welding gun to axially compress the contact tip between the gas diffuser and the nozzle, wherein the gas diffuser and the nozzle are independent from one another.
A welding gun for an arc welding system, comprising:
- a gas diffuser comprising a first member;
- a nozzle comprising a second member;
- and
- a contact tip disposed intermediate the first member and the second member,
- wherein the contact tip is axially compressed between the first member and the second member by reducing the axial displacement between the first and second members.
A welding system, comprising:
- a welding gun adapted to receive a wire from a wire feeder, the welding gun comprising
- a gas diffuser comprising a first member;
- a nozzle comprising a second member independent and movable relative to the first member;
- and
- a contact tip, wherein the first member, the second member, and the contact tip are adapted to receive the wire therethrough, and wherein the contact tip is axially compressed between the first and second members.
A welding system comprising:
- a nozzle, comprising a first portion adapted for abutment with a contact tip to urge the contact tip towards a first surface located opposite the first portion;
- and
- a gas diffuser, wherein the nozzle and the gas diffuser are configured to move axially inward toward one another to capture the contact tip, and the contact tip comprises a shoulder configured to be axially compressed between two portions of the welding system.
A welding system, comprising:
- a gas diffuser, comprising a tapered surface adapted for abutment with a corresponding surface of a contact tip;
- and
- a nozzle, wherein the gas diffuser and the nozzle are configured to axially compress the contact tip, wherein the gas diffuser and the nozzle are independent and/or movable relative to one another.
