Tweco® Self Insulated Copper Nozzle with 3/8" size is designed for standard gas diffuser for use with up to 180 A Tweco® no.1 MIG guns. 2.224" Nozzle with 3/4" OD is ideal for use in light to medium duty welding application up to 180 A. It features part number rolled stamped on the outer surface for easy identification. Nozzle with M11-1.5-6H threads size is made of 122 DHP copper alloy and is best suited for higher heat applications requiring longer electrical stick-out or in cases where the nozzle touches the work piece. It has a 3-piece design without an additional insulator includes a nozzle housing, which is cut and formed from copper alloy tubing, a nozzle insert machined from a solid brass and nozzle insulator constructed of silicone material. It has nozzle insert that allows machining of internal threads in order to match the gas diffuser. It features threads onto the gas diffuser. Nozzle offers electrical insulation required from the gas diffuser using the nozzle insulator. Nozzle is sold as 2 per pack.

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
