The insulator is a small part that does one job: keep the nozzle electrically isolated from the diffuser and contact tip assembly so you don't get stray arcing or a nozzle that runs hot. This Tweco-style #4 insulator suits the 300 and 400 amp Tweco-pattern torches.

It's cheap and easy to overlook, right up until it cracks or melts and the torch starts arcing where it shouldn't. Keep one in the spares tin alongside your tips and nozzles.

Full specs are in the tabs below.
