Product Description:
The Tweco® Brass Nozzle with a 0.625" bore size is specifically designed for utilization with a standard gas diffuser. With a 3.018" nozzle size and an outer diameter of 0.875", it is ideal for light to medium duty welding applications up to 250 A. For easy identification, the part number is rolled stamped on the external surface.
This copper alloy nozzle features a flush contact tip relationship of 0.062". Its 3-piece design eliminates the need for an additional insulator and includes a nozzle housing, which is cut and formed from 122 DHP copper alloy tubing. It also incorporates a nozzle insert machined from solid brass and a nozzle insulator made from silicone material.
The nozzle insert enables the machining of internal threads to match the gas diffuser, which features threads on the standard EL gas diffuser. The nozzle provides the necessary electrical insulation required from the gas diffuser by utilizing the nozzle insulator.
The nozzle is conveniently sold as a pack of two. Its part number is rolled stamped on the outside surface for easy identification. The 3-piece design eliminates the necessity for an additional insulator. The nozzle housing is meticulously crafted from 122 DHP copper alloy tubing. The nozzle insulator, made from G7 silicone material, provides the electrical insulation required from the gas diffuser. The nozzle insert, machined from solid brass alloy, guarantees internal threads that perfectly match the gas diffuser. The nozzle threads onto a standard EL gas diffuser.
When it comes to application preferences, recessed tips are generally suited for higher heat scenarios where longer electrical stick-out is needed or when the nozzle may come into contact with the work piece (tack, spot, and stitch). Flush tips, on the other hand, are typically employed when a shorter electrical stick-out is used, resulting in shorter or tighter arc lengths and bringing the tip closer to the work piece. Protruding tips are commonly used when welding open root pipe or any joint that requires the welder to work in a tight weld joint. However, using protruding tips increases the risk of arcing the tip to the work piece, potentially damaging front end parts and necessitating replacement, leading to downtime.
