OTC Nozzles
OTC nozzles — cylindrical, tapered and straight gas nozzles for 350 and 500 A OTC MIG torches, plus a ceramic diffuser for the 350 class.
Products
Gas nozzles for OTC-pattern guns: cylindrical, tapered and straight profiles for the 350 A class, a straight nozzle for the 500 A, and a 350 ceramic diffuser listed alongside.
Which nozzle profile should I run on an OTC gun?
Match the amperage class first — 350 or 500, as named in each listing — then pick the profile: straight or cylindrical for general coverage, tapered where joint access is tight. Profiles here mirror the genuine OTC reference numbers for easy cross-matching.
WeldCo keeps the 350 and 500 class fitments available for its Melbourne and Adelaide OTC customers.
