Contact tip and receiving assembly of a welding torch
A welding torch system includes a receiving assembly to receive a contact tip and a welding nozzle. The welding torch system also includes a locking element that retains the contact tip in a partially secure position. Further, the welding torch system includes the welding nozzle configured to couple to the receiving assembly to retain the contact tip in a fully secure position.
1. A welding torch system comprising:
a welding nozzle;
a receiver configured to receive a contact tip and the welding nozzle;
a retainer configured to retain the contact tip in a partially secure position when the receiver receives the contact tip and not the welding nozzle, and retain the contact tip in a fully secure position when the receiver receives both the contact tip and the welding nozzle; and
a retention band disposed around the retainer, wherein the retention band is configured to provide a first force on the retainer to establish the partially secure position of the contact tip.
2. The welding torch system of claim 1 , wherein the contact tip is toollessly removable from the receiver when the contact tip is in the partially secure position.
3. The welding torch system of claim 1 , wherein the contact tip is not toollessly removable from the receiver when the contact tip is in the fully secure position.
4. The welding torch system of claim 1 , wherein the retainer is positioned within a radial orifice of the receiver.
5. The welding torch system of claim 1 , wherein the welding nozzle is configured to provide a second force on the retainer while the welding nozzle is coupled to the receiver to establish the fully secure position of the contact tip.
6. The welding torch system of claim 4 , wherein the receiver further includes a cooling channel.
7. The welding torch system of claim 6 , wherein the cooling channel extends adjacent to an axial length of the contact tip when the contact tip is received by the receiver, such that the contact tip is cooled by shielding gas when shielding gas is directed through the cooling channel.
8. The welding torch system of claim 6 , wherein the cooling channel is in fluid communication with a gas port of the receiver.
9. The welding torch system of claim 1 , wherein the retention band is elastically deformable.
10. The welding torch system of claim 5 , wherein the retention band abuts the retainer when the contact tip is received by the receiver, the first force being provided via abutment between the retention band and the retainer.
11. The welding torch system of claim 10 , wherein the welding nozzle abuts the retention band when the nozzle is received by the receiver, the second force being provided via abutment between the welding nozzle and the retention band.
12. A welding torch system, comprising:
a welding nozzle;
a receiver configured to receive a contact tip and the welding nozzle, wherein the receiver includes a cooling channel, and wherein the cooling channel extends parallel to an axis of the receiver; and
a retainer configured to retain the contact tip in a partially secure position when the receiver receives the contact tip and not the welding nozzle, and retain the contact tip in a fully secure position when the receiver receives both the contact tip and the welding nozzle, wherein the retainer is positioned within a radial orifice of the receiver.
