Easy identification - part no rolled stamped on the outside surface
Machined from 360 brass alloy bar stock to ensure consistent dimensional stability

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
