Tweco Coarse Threaded Copper Nozzle with 0.625″ bore size is designed for standard gas diffuser and is machined from a solid copper alloy bar to provide consistent dimensional stability as well as efficient heat dissipation. 1.53″ Nozzle with 1.07″ OD is ideal for use in medium to heavy duty welding application up to 450 A. It features part number rolled stamped on the outer surface for easy identification. It has a 2-piece design and is made of 145 tellurium copper alloy. Nozzle with flush contact tip relationship 0.062″ is best suited where a shorter electrical stick-out is used sometimes resulting in shorter/tighter arc lengths. It is sold as 2 per pack. KEY FEATURES Easy identification – part no rolled stamped on the outside surface Machined from a solid copper alloy bar that assures consistent dimensional stability and efficient dissipation of heat Nozzle housing and nozzle insulator sold separately A separate nozzle insulator is used to thread onto the conductor tube and provide insulation to the nozzle Two-piece nozzle design – nozzle housing threads onto the nozzle insulator Recessed Tips are generally used for higher heat applications where longer electrical stick-out is required, or in cases where the nozzle may touch the work piece (tack, spot, and stitch) Flush Tips are generally used where a shorter electrical stick-out is used sometimes resulting in shorter/tighter arc lengths, This brings the tip closer to the work piece Protruding Tips are generally used when welding open root pipe or any joint that requires the welder to get into a tight weld joint. However the down side to this is the chance of arcing the tip to the work piece, which could damage front end parts resulting in downtime needed to replace Applications Used in medium to heavy duty welding application up to 450 Amp
